No Waiting Rooms. No Stress.
Compassionate Care on Your Schedule.
We believe quality healthcare should be convenient, not a chore. That’s why we’ve moved the paperwork to your phone—fill out your forms in minutes from the comfort of your couch.

A Legacy of Service in Chester & Brookhaven.
I’m Dr. David DeFries. As a third-generation chiropractor, I’ve seen firsthand how an accident can disrupt a family’s life. Our neighbors in Upland, Parkside, and Aston deserve comprehensive care that respects their time. Whether you’re recovering at home or managing a busy work schedule, I bring the clinic to you. You get direct access to me—no middleman, no call centers, just expert care delivered to your door.

When your doctor and lawyer are on the same page, your claims get processed faster and your injuries are documented correctly the first time. We take the guesswork out of the process.
Insurance & Attorney Coordination — Handled
Most car accident patients are already dealing with enough stress. Insurance paperwork, documentation, and coordination with attorneys shouldn’t be another burden. Mobile chiropractic care includes proper documentation and communication to support your claim, so you can focus on recovery.
- Auto insurance (PIP) accepted when applicable
- Documentation prepared to support injury claims
- Coordination with attorneys when involved
- Clear records of care related to the accident
Care is based on clinical findings and patient response, not legal timelines or outside pressure.
Proudly serving Chester (19013), Chester Township (19015), Upland, Eddystone, and surrounding Delaware County neighborhoods.

Mobile Care: Your Questions
Does this cost me anything out of pocket?
Yes. Pennsylvania is a "No-Fault" state. Your PIP (Personal Injury Protection) covers medical expenses, including chiropractic care, up to your policy limit (which is at least $5,000 by law) regardless of who was at fault.
Will my insurance rates go up?
Generally, no. Using your PIP medical benefits is a right you already pay for. It is intended for your recovery and usually does not affect your premiums.
How does a mobile chiropractic visit work?
We bring the clinic to you. Dr. Define arrives at your home or office with a professional, portable adjustment table and all necessary equipment. All we need is a small space (about the size of a yoga mat) to set up. You get the same high-quality adjustment you'd receive in a building, but without the travel or waiting rooms.
Do I need a lawyer first?
No. You can start treatment immediately. We coordinate with many local Delaware County law firms to ensure your records are handled professionally.
