What happens at a trial class
Book and sign online
Pick a class, then e-sign the participation waiver (a parent or guardian signs for anyone under 18). You can read the waiver before booking.
Meet your coach
Arrive 10 minutes early. A coach shows you the mat rules, fits gloves if needed and introduces the group.
Train, then talk
Take the full class. Afterward we recommend a level and explain plan options — no pressure and no same-day signup required.

Skills that carry off the mat
- Safe falling, rolling and balance before any partner work
- Pad striking with technique, not power
- Takedown defense and getting back to feet
- Anti-bullying talk-first scenarios: voice, posture, walk away, tell an adult
- Listening, turn-taking and respect for partners
We don't promise specific outcomes. Every child progresses at their own pace.
Stripes every few weeks, belts every few months
Kids earn up to four stripes per belt by showing specific skills and behavior. Belt tests happen in class, in front of parents, never for an extra fee.
The Crestline kids belt system
Parents' quick guide

Bring your child to a free class
A parent or guardian signs the waiver and stays on site for the first visit.

Two classes per week, cooperative partners, no sparring. At the end, an in-class Level 1 assessment.
Weeks 1–4
Move & protect
Stance, footwork, guard, breakfalls, jab-cross on pads, standing up safely.
Weeks 5–8
Clinch & takedowns
Sprawl, clinch control, basic takedowns, defending against the wall.
Weeks 9–12
Ground basics
Mount and guard escapes, positional control, combining it all in drills.
Adult MMA and Crest Conditioning
Adult MMA (75 min) blends striking, wrestling and grappling. Controlled sparring is optional and only after Level 1, with headgear and mouthguards.
Crest Conditioning (45 min) is kickboxing-style fitness on bags and pads with no partner contact — scalable for any fitness level.
Health note: please consult your physician before starting any exercise program. We do not make weight-loss or medical claims.

About fighter records and titles
We list coaching credentials only when they can be independently verified. We do not claim competition titles, fighter records or affiliations without documentation and the person's written consent.
Home / Safety
Safety & SafeSportHow we keep the mat safe
MMA has no national governing body that binds a gym like ours to SafeSport. We adopt its standards voluntarily, and publish them here.
Two-adult rule
At least two adults are present for every class or activity involving minors. Doors and windows stay unobstructed.
Transparent messages
No private texts or DMs between coaches and minors. All messages go through the family account with a parent copied.
No private video calls
No one-on-one video sessions with minors. Kids virtual classes are group-only and never recorded.
Screened staff
Background checks and abuse-prevention training for all coaches and volunteers before they work with members.
Head-injury protocol
Anyone with a suspected head injury stops training for the day and returns only with written clearance from a licensed health-care provider.
First aid on site
AED and stocked first-aid kit at the front desk. At least one CPR-certified coach on every shift.
Separate mats, open sightlines
The kids mat and adult mat are separated, and the parent viewing area overlooks both through a glass wall. Mats are cleaned and disinfected after the last class every day.
- Shoes off on the mat, on in the lobby and restrooms
- Clean training clothes, trimmed nails, no jewelry
- Skin conditions: stay home until cleared
Tell us — we act on every report
Email support@crestline-co.com or speak to the Program Director in person. Reports can be made anonymously.
If a child is in immediate danger, call 911. To report suspected abuse or neglect in Ohio, call 855-O-H-CHILD (855-642-4453).
Whether or not a staff member is a mandated reporter under Ohio R.C. 2151.421, our policy requires every staff member to report suspected abuse or neglect to Franklin County Children Services or law enforcement the same day.
Competition policy
We do not organize, promote or sell tickets to fights. Kids never compete in bouts. Amateur MMA in Ohio is overseen by the Ohio Athletic Commission (R.C. ch. 3773); adults interested in competing are referred to sanctioned events and are responsible for meeting commission requirements.
Photos & video of minors
We photograph or film minors only with a signed parent release, and never publish a child's full name.

Home / Membership policies
PoliciesMembership policies
Cancellation, refunds, waivers, minors and studio rules — in plain English.
Cancellation
Three-business-day right to cancel. Under the Ohio Prepaid Entertainment Contract Act (R.C. 1345.41–1345.50), you may cancel any membership agreement until midnight of the third business day after signing. The statutory cancellation notice appears in bold type on every agreement.
Month-to-month plans may be cancelled any time with 30 days' written notice by email, in person or in your member account. 12-month agreements may be cancelled early for a $75 early-termination fee (or the remaining balance, if lower); no agreement runs longer than 12 months, well within the limits of R.C. 1345.42.
Death, disability or relocation. You may cancel upon death or disability (as certified by a physician) or if you move more than 25 miles from the academy, and receive a pro-rata refund of prepaid amounts.
Refunds & freezes
Refunds owed under a valid cancellation are issued within 30 days to the original payment method. Memberships may be frozen for up to 2 months per year for injury, travel or school schedule changes; billing pauses during a freeze.
Trials & automatic renewal
The free trial class requires no payment details and never converts to a paid plan. Paid plans renew automatically at the price shown at signup until cancelled; we email a receipt confirming your price, renewal date and how to cancel. We will notify you at least 30 days before any price change. Online plans can be cancelled online in your account. (Federal ROSCA, 15 U.S.C. §8401–8405.)
Participation waiver & assumption of risk
Martial arts involve physical contact and a risk of injury. Every participant (or their parent or guardian, if under 18) e-signs a waiver and assumption-of-risk agreement before the first class. Online members sign a version covering unsupervised training at home. Each signature is stored with version number and timestamp. You can read the current waiver (version 2026-10) before booking and request a copy of your signed waiver at any time from support@crestline-co.com. Nothing in the waiver limits rights that cannot be waived under Ohio law.
Minors policy
- A parent or guardian completes registration, the waiver, emergency contact and relevant medical information.
- Parents of children under 13 remain on site during class.
- Children under 13 never hold their own online accounts; parents own the account and add a profile (COPPA, 16 CFR Part 312).
- No sparring for ages 4–12. Teen sparring requires signed parent consent and coach approval.
- We do not enter children into fights or bouts.
Photos, video & recordings
We photograph or film members only with signed consent; for minors, a parent release. Adult virtual classes may be recorded with notice at the start and are available to members only. Kids virtual classes are never recorded. Library videos and class recordings are owned by Crestline MMA LLC and licensed to members for personal, non-commercial use; members may not record, redistribute or post them.
Studio rules
- Shoes off on the mat; sandals in the lobby and restrooms.
- Clean uniform or athletic clothes every class; short nails; no jewelry.
- Stay home with any contagious skin condition until cleared.
- Tap early, tap often — and respect every tap immediately.
- No outside instruction of other members' children.
Disclaimers
Consult a physician before beginning any exercise program. We make no guarantees of fitness, weight-loss, self-defense or competitive outcomes; results vary by person. Crestline MMA is a recreational training academy, not an accredited school, and our in-house levels are not a credential recognized by any governing body.
This document describes the rules and disclosures for this particular business and its stated services. Its operational details are drawn from the supplied brand reference; unverified website technology is not represented as active.
01 Identity and contact
This notice concerns Crestline MMA LLC, Ohio, operating the site crestline-co.com. Business address: 3380 Indianola Ave, Unit B, Columbus, OH 43214. Privacy inquiries may be sent to support@crestline-co.com. Effective year: 2026. The website domain is the current public address; it need not match the company’s legal name.
02 What this business learns in the course of its work
Crestline MMA LLC operates crestline-co.com in connection with family martial arts classes and online technique instruction. In that setting, relevant individuals include parents, minors, adult students and coaches. The reference describes information such as guardian contact details, class registrations, attendance and any emergency information voluntarily required. We do not assume every possible field is collected online: the specific inquiry, booking or enrollment form determines what is actually submitted.
03 Cookies and analytics status
The supplied brand reference does not establish an audited cookie inventory or named analytics platform. Essential browser storage may be needed for security or a functional checkout. Any nonessential analytics, marketing pixels or cross-site identifiers must be disclosed accurately and subject to legally required consent or opt-out choices before deployment. This notice does not assert that such tools are active.
04 Use of personal information
Relevant purposes include answering requests, arranging services, performing an agreed engagement, maintaining transaction records, detecting abuse and satisfying legal obligations. Promotional messaging is not inferred from merely contacting the business. Any optional marketing signup should explain what will be sent and provide a usable unsubscribe mechanism.
05 Project material and confidentiality
Information connected with youth and adult in-person MMA classes with online instruction may reveal personal preferences, plans, creative work or commercially sensitive details. Such material should be available only to people who need it to deliver the requested service, respond to an inquiry, maintain records or meet legal duties. A public portfolio or promotional use requires a lawful basis and appropriate permissions; an inquiry alone does not authorize publication.
06 Operational disclosures specific to the service
Where service delivery requires outside participants, only necessary details should be shared with relevant instructors, specialists, venues, production partners, carriers or other contracted providers, as applicable to family martial arts classes and online technique instruction. This description is conditional on the actual service; it does not assert that all these categories are engaged or that customer lists are sold.
07 Outside recipients and transfers
Information may be shared with providers actually engaged to operate the site or perform a contracted service, and with advisers or authorities when justified. A business transfer may require legally appropriate safeguards. International processing, if any, must satisfy applicable transfer rules. This document does not invent named vendors or claim that customer information is sold.
08 A practical boundary on sensitive details
The site is not a general-purpose vault for identity documents, medical histories or other sensitive records. Individuals should avoid submitting unnecessary sensitive information. Where a particular service legitimately requires an accommodation, safety contact, participant permission or other sensitive detail, it should be requested separately, explained at collection and protected appropriately.
09 Legal bases and individual choices
Where relevant privacy regimes apply, processing may rest on contract performance, legal obligations, proportionate legitimate interests or consent for activities that require it. Depending on location and legal thresholds, people may have rights to access, correct, delete, receive or restrict data, object, withdraw consent or appeal decisions. Requests go to the contact above, subject to lawful identity checks and exceptions.
10 Minors, updates and accuracy
Unless the offering expressly addresses minors through an authorized guardian, the site is not intended to solicit personal information from children under 13. Material changes to actual data practices should be reflected in a revised notice and communicated where required. Inconsistent or inaccurate details should be corrected before this notice is published.
11 Children and guardians
For youth classes, the responsible parent or guardian should control registration and necessary permissions. Collect only age-appropriate information needed for instruction, safety and communication; a general website must not knowingly solicit information from children under 13 without applicable parental-consent safeguards.
12 Direct communications
An inquiry or service request can include a name, reply address, telephone number if requested, the requested service, scheduling details and the contents of correspondence. A purchase or paid booking may additionally create transaction identifiers, amounts and payment status. Payment credentials may be handled by a processor; the precise checkout architecture requires verification.
13 Retention and protection
Information should be kept only as long as needed for the particular engagement, statutory accounting, claims, security or legitimate operational purposes. Retention may vary between service files, correspondence and financial records. Exact periods should be stated only when confirmed. Reasonable access, confidentiality and security measures should be used; absolute security cannot be promised.
14 Visitors and technical records
Accessing pages may expose an IP address, user-agent information, request time, requested URL and technical error or security records to the site’s infrastructure. These are described as categories that commonly arise in website delivery; no specific hosting provider or tracking product is asserted without a technical inventory.
This document describes the rules and disclosures for this particular business and its stated services. Its operational details are drawn from the supplied brand reference; unverified website technology is not represented as active.
01 Who offers the services
The operator is Crestline MMA LLC, a business identified in the reference as organized in Ohio. Its business address is 3380 Indianola Ave, Unit B, Columbus, OH 43214. The website for these Terms is crestline-co.com; customer correspondence goes to support@crestline-co.com. These Terms are dated 2026 and apply subject to any signed engagement terms and nonwaivable consumer protections.
02 The service being contracted
Crestline MMA LLC is associated with family martial arts classes and online technique instruction. Website descriptions introduce the offerings; a confirmed booking, enrollment, proposal or other written agreement should identify the purchased scope, dates, deliverables and any exclusions. No website inquiry alone guarantees availability.
03 Website and content rights
Branding, site copy, educational materials, photographs, diagrams, audio and other protectable materials belong to their respective rights holders. Browsing permits ordinary personal viewing, not wholesale commercial copying. Rights in client-created work and final deliverables depend on the relevant project agreement and applicable law.
04 No invented outcomes
Examples, portfolios, educational descriptions and marketing statements are not guarantees of earnings, professional advancement, artistic success, event conditions or other individualized outcomes. Any express guarantee must be stated clearly and honored as required by law.
05 Price, cancellation and scope
The reference describes monthly tuition for age-based programs and an online academy. Enrollment must clearly state billing cadence, cancellation, pauses and any nonrefundable amounts; no unspecified minimum commitment is imposed here.
06 Rights, safety and professional boundaries
Contact sport carries injury risk. Guardians must authorize minors’ participation, and child-safety practices, age-group separation and supervised training matter. A risk acknowledgement cannot waive rights that applicable law protects.
07 Third-party responsibilities
Some services depend on independent venues, platforms, suppliers or specialists. The relevant written agreement should allocate duties transparently. Mention of a third party is not an endorsement or a guarantee of that party’s performance; mandatory duties of the operator cannot be waived by simply naming a vendor.
08 Changes and responsibility
Because youth and adult in-person MMA classes with online instruction may depend on schedules, participants, third-party resources or customer input, material changes should be documented and handled under the applicable written agreement and mandatory law. Neither a promotional example nor a website overview overrides a confirmed written scope.
09 Information and communications
Customers should give accurate information and use the contact address for scheduling or contractual concerns. Service-specific forms and policies must not contradict the promises made at checkout or in the signed agreement. The separate Privacy Policy describes handling of personal information.
10 What prices mean
Displayed rates and package examples may depend on scope, location, timing or availability. Taxes, third-party charges, materials, travel and other material costs should be itemized before acceptance where relevant. Changes to a confirmed order require an appropriate contractual basis or customer agreement.
11 Customer cooperation
Customers should supply accurate contact details, relevant specifications and timely decisions for youth and adult in-person MMA classes with online instruction. Requests beyond the agreed scope may require a separate written quote or schedule adjustment. The provider remains responsible for its own legally required performance and cannot shift all operational risk to the customer.
12 Agreement formation
Descriptions and starting prices invite inquiries or orders but do not themselves reserve a place or create a fully scoped engagement. A binding commitment arises under the actual checkout, written confirmation or signed service agreement, subject to applicable law. Any deposit, recurring charge or automatic renewal must be clearly disclosed before consent.
13 Legal limits and disputes
Nothing in these Terms removes statutory refund rights, liability for fraud or willful misconduct, or other obligations that cannot be excluded. Any permitted limitation must be interpreted narrowly. Contact the business to raise concerns; no mandatory arbitration, class waiver or exclusive jurisdiction is invented here.
14 Fair use of the site
Do not misuse payment systems, attempt unauthorized access, distribute malicious software or misrepresent another person. We may take proportionate measures against unlawful activity, without limiting legally protected access or criticism.
15 Updates and severability
These Terms may change prospectively, with the revised date identified. A later website revision does not retroactively rewrite an accepted order without lawful agreement. If a clause is unenforceable, the remainder may remain effective to the extent allowed by law.
