If you are looking for a chiropractor in Walnut Creek, it helps to know that chiropractic practices are not all built the same way.

Every case starts with a determination of what is actually wrong, and the treatment that follows is built around that. Dr. Douglas F. Cancel, D.C. has practiced in California since 1983.

Choosing A Practice
The Two Kinds of Chiropractic Practice
They are organized around different questions, which is why they suit different situations.
Organized around a schedule
High-Frequency Adjustment Practices
The central treatment is the spinal adjustment, repeated at regular intervals over an extended period. Visits tend to be brief and similar to one another, and the schedule itself functions as the plan.
This works for a lot of people. Where it tends to fall short is when a particular structure is injured — a tendon, a disc, a joint under repeated overload — and the adjustment is not addressing that structure.
Organized around a finding — this clinic
Diagnosis-First Sports Practices
The first visit is spent figuring out exactly what is injured and what is overloading it. Treatment then follows that finding: hands-on care directed at the problem structure, followed by progressive strength work to rebuild capacity so the issue is less likely to return.
Because the plan is built around a specific finding, it has a clear direction and an endpoint. When the findings change, the plan changes with them.
What should happen at a first appointment
- A history detailed enough to establish how the problem behaves — what provokes it, what settles it, what came before it
- Physical examination and orthopedic testing carried out before treatment starts, not after
- Observation of how you actually move and load the area, not table findings alone
- A request for imaging or further workup when the examination points to it
- A clear account of the findings and the proposed plan, given to you before you agree to a course of care
How Care Works
Relieve, Restore, Rebuild
Three stages. The third is the one most often left out.
Relieve
Settle the irritated tissue and bring the pain down, using manual therapy and chiropractic care directed at what the examination found.
Restore
Address the movement problem that put the tissue under load in the first place, through targeted soft-tissue work and mobility training.
Rebuild
Load the area back up under supervision until it tolerates what you need it to do. Skipping this stage is why problems recur.
Why It Matters Here
A Clinician Who Has Trained Seriously
Dr. Cancel is a former National-level competitive bodybuilder and a lifelong strength-training athlete. That matters clinically for a specific reason: a great deal of musculoskeletal injury is a loading problem, and judging load accurately is easier for someone who has spent decades managing it in their own training.
It shows up in the practical questions — how much you can keep doing while the tissue settles, what to change rather than what to stop, when soreness is information and when it is a warning. Those answers are the difference between a plan you can live with and one you abandon.
It applies well beyond the barbell. A runner adding mileage, a tradesperson lifting all day, a tennis player through a season, and a lifter under a heavy squat are all managing the same underlying variable.
What care looks like in practice:
- Assessment framed around what you actually do, not a generic activity profile
- Manual therapy directed at the structures carrying the highest load in your activity
- Rehabilitation designed to keep you moving wherever the diagnosis allows it
- Supervised strength rehabilitation carried out on site, under Dr. Cancel’s direct clinical supervision
- Practical guidance on managing training and workload while you recover

Common Questions
Questions About Choosing a Chiropractor
What are the two types of chiropractors?
The practical division is between practices built around adjustment frequency and practices built around diagnosis. In the first, the spinal adjustment is the treatment and it is repeated on a schedule. In the second, the examination determines what is wrong and the treatment is assembled to match — usually manual therapy and chiropractic care alongside progressive loading of the affected tissue.
Both are recognizable as chiropractic. They differ in what determines the plan: a calendar in the first case, a finding in the second. Performance Sport Care works the second way.
What are red flags for chiropractors?
The most reliable warning sign is treatment beginning before an examination has been done. A first appointment should produce a history, hands-on testing, and a stated finding before anything is treated.
Others worth noticing: a long prepaid package presented before a diagnosis exists; an identical protocol regardless of what a patient presents with; claims of curing conditions outside the musculoskeletal system; and an inability to say what would change the plan or when it would end. A practice working from a diagnosis can answer those questions specifically.
How do I choose a chiropractor in Walnut Creek?
Start by matching the practice to the problem. If you want regular maintenance care, an adjustment-frequency practice is built for exactly that. If something specific is injured — particularly if you have already tried care that didn’t hold — look for a practice that examines thoroughly, names the structure involved, and includes progressive loading in the plan.
Ask what the first appointment consists of. The answer tells you most of what you need to know.
Do I need a referral to see a chiropractor in California?
No. Chiropractors are direct-access providers in California, so you can book an appointment yourself. If you already have imaging or records from another provider, bringing them helps — but nothing is required to be seen.
I’ve already tried chiropractic, physical therapy, or injections and I’m still in pain. Can Dr. Cancel help?
Yes — in fact, this describes a large portion of our patients. When generic chiropractic adjustments, standard physical therapy, or injections fail to produce a lasting result, the most common reason is that the original diagnosis was incomplete or incorrect.
Does Performance Sport Care accept insurance?
Performance Sport Care is an out-of-network provider. You pay in full at the time of service, and as a courtesy we submit a claim to your plan within 24 hours, so any out-of-network reimbursement is paid directly to you. Coverage varies by plan, and we are not contracted with managed-care or HMO plans, including Kaiser, or currently with Medicare.
