When pain starts deciding what you can and cannot do

Maybe it hurts to get through the workday. Maybe you have stopped sleeping comfortably, lifting the way you want to lift, playing golf, gardening, running, traveling, or training without having to work around the same problem.

Sometimes the limitation matters even more than the pain.

My goal is to help you hurt less, move more comfortably, regain strength and confidence, and get back to the activities that matter to you.

You do not need to be an athlete to be cared for like one.

At Performance Sport Care, that means taking your problem seriously, understanding what your body needs to be able to do, and building care around getting you there.

Relief matters. So does what you can do afterward.

There is an important difference between feeling better for a while and being better prepared for the demands of your life.

Hands-on treatment can help reduce pain and improve comfortable movement. But if the problem has also left you weaker, less mobile, less confident, or unable to tolerate the activity you want to return to, symptom relief may only be the beginning.

That is why I combine chiropractic and manual care with supervised progressive strength rehabilitation in the same practice, under one plan.

Relieve.

Work to reduce pain and restore enough comfortable movement to start doing more.

Restore.

Rebuild the motion, strength, control, or tolerance that has been lost.

Rebuild.

Progress until your body is better prepared for the work, training, sport, or everyday activity you want it to handle.

Not everyone needs every step, and the sequence is not identical for every person. The plan changes as you change.

Beyond erasing pain no one else was able to solve for twenty years with the therapy I received, I also did a workout plan with them and built the strengh needed to never feel that pain again. I love being in my body again and can do activities like I was fifteen years younger! Highly recommend doing both their therapy (passive) + their workout program to get to a place that is more than therapy could ever get you to imo. Awesome folks who get to know you is a big plus too.

⭐⭐⭐⭐⭐ I’ve had a great experience with Dr. Douglas Cancel and Dana at Performance Sport Care. I came to them with some shoulder and back concerns, and both have been incredibly helpful throughout the process. Dr. Cancel took the time to address my concerns, and Dana has been great to work with on the exercise and training side. I really appreciate their knowledge, professionalism, and willingness to help me improve how I feel and move. It’s clear they care about their patients and want to help them get back to feeling their best. I highly recommend Dr. Cancel, Dana, and the team at Performance Sport Care to anyone dealing with aches, pains, or mobility issues. Great people and great care!

I cannot say enough good things about Dr. Doug Cancel at Performance Sport Care. Having dealt with chronic pain for many years, finding someone who genuinely understands and provides consistent relief is rare. Dr. Doug has been an incredible resource for me over the years. He is always available when I need him, deeply compassionate, and completely dedicated to helping his patients get back to living comfortably. If you are struggling with pain and feel like you've run out of options, I highly recommend Dr. Doug. He is truly the best!

I started seeing Dr. Cancel about two weeks ago for a serious knee injury I sustained in May 2026 during Brazilian jiu-jitsu. With a long background in wrestling and grappling, plus a physically demanding job, that knee already had years of wear and tear. Dr. Cancel was very understanding of that background and clearly knowledgeable about this kind of injury. After the injury I had an MRI, and the initial assessment was that it wasn’t serious. Dr. Cancel saw it differently, and I can’t thank him enough for his experience, professionalism, and attention to detail. His treatments and adjustments have stabilized my knee, improved blood flow and recovery, and restored function not just to my knee but to my lower body overall. If you’re a grappler or combat sports athlete dealing with a nagging or misdiagnosed injury, I highly recommend him. - Nick T.

​Dear Dr. Cancel, ​Thank you for always treating me with dignity, respect, and patience. I truly appreciate that you take the time to sit with me without rushing and explain my MRIs and how the body works in clear, easy-to-understand terms. ​You have successfully treated many of my sports injuries over the years, allowing me to keep doing the things I love in life. I’m sharing this note in the hope that someone else looking for high-quality, compassionate care finds their way to your practice. ​With sincere gratitude, Chris

At 59, I'm still competing in bodybuilding, and I owe much of that to Doug Cancel. When I lived in Walnut Creek, I saw Doug whenever anything started to bother me, and he corrected it in a single session. To this day, I've never had a gym-related injury. After I moved, I never found anyone half as effective. When I developed shoulder pain and limited range of motion, I tried many practitioners and nothing helped. Finally, I flew to California, rented a car, and had Doug treat me. It was painful, but the problem was resolved in one session and the pain never came back. More recently, I had a severe shoulder injury at work. I improved a lot, but an underlying issue kept the pain coming back and disrupted my sleep and training. On a video call, Doug diagnosed the root cause, a deeply buried muscle in my upper back that was throwing off my shoulder's motion, and gave me movements to correct it. That got me back in time to compete in 2 divisions and 4 classes at the Florida State Championship, where I medaled in all 4. Calling Doug effective is accurate, but it falls short. He is a true expert in his field.

If you are serious about ending your pain, Douglas Cancel should be your first choice. His tagline could be "Cancel your pain." He listens, he understands and he helps you. Even better, he teaches you how to avoid pain in the future, 5 stars for sure.

I have been having an ongoing problem with my elbow for three years. All of the doctors I have seen in the past only tried addressing the pain in the elbow. Ive seen doctors, chiropractors, physical therapists, gotten multiple PRP injections, and the pain kept coming back. Dr Cancel was the first one to address WHY the pain kept coming back, and helped me understand what was actually going on. (It wasn't just the elbow that was the problem). No one else went further than the elbow. His treatment, along with his recommended maintenance program, has given me great progress, and a freedom from the frustration of not knowing why this was happening. I feel more confident now than ever that I will be able to do my job without constant pain and get back to the hobbies I used to enjoy. Cant recommend him enough. I also started seeing Dana to do some supervised strength training to aid with the recovery and learn the correct form of exercises to avoid future injuries. For years now, I have been too afraid of stepping into a gym for fear of injury. I now feel a lot more confident to go on my own. If you are looking for a very personal and welcoming place, this is it.

Dr Doug Cancel is amazing he worked on me years ago on my back and worked miracles where delayed my back surgery for me over 10 years where the doctors said nothing else we can for me besides surgery. And in the delayed time the technology changed dramatically where it speeded up my recovery time. Now having issues with my neck and again doctors want to do surgery with minimal evaluation just by checking my images and not by checking me out for all my symptoms. So again i decided to go get checked out by Doug Cancel. He did a complete evaluation and even went over all the doctors different doctors notes to come up with a game plan and to again postpone surgery until I really need it just like my back which again the technology will be changed dramatically. I live in Placerville and drive all the way to Walnut Creek to see him thats how much I believe I know he can help me again. Thank you Doctor Doug Cancel for being so caring to your patients!

Treatment and rehabilitation belong together

If hands-on care helps you move more comfortably, I want to use that improvement.

If rehabilitation shows that a certain movement is still painful, weak, restricted, or poorly tolerated, I want that information influencing what we do next.

That is difficult to accomplish when treatment happens in one place, rehabilitation somewhere else, and nobody is watching the whole process.

At Performance Sport Care, the treatment table and the strength-rehabilitation floor are part of the same practice.

Depending on what your examination shows, care can include chiropractic adjustments, manual treatment, assisted stretching, specific exercise, and progressive strength work. I establish the plan and direct its progression.

The point is not to fit you into a treatment protocol.

The point is to keep asking: What are you trying to get back to, what is keeping you from doing it, and what needs to change next?

A practice built for more than a quick treatment

I have been licensed in California since 1983 and practicing in Walnut Creek since 1985.

I am also a former National-level competitive bodybuilder and a lifelong strength athlete who still trains.

That background has shaped the way I think about rehabilitation. In high-level professional athletics, evaluation, treatment, rehabilitation, and return to performance are treated as connected parts of the same process.

You do not need to be a professional athlete to benefit from that philosophy.

Your version of “performance” might be a heavy squat or a tennis match. It might also be getting through a long workday, carrying luggage through an airport, walking hills, gardening, playing with your grandchildren, or getting back to the gym without constantly protecting one painful area.

Performance is personal.

What matters is what you need your body to do.

Strength rehabilitation that starts where you are

Strength rehabilitation does not mean everybody needs to train heavily.

For one person, the right starting point may be a two-pound dumbbell and a precise shoulder movement. For another, it may eventually be a loaded barbell.

The exercise has to fit the person.

I develop the rehabilitation plan from my examination findings and direct its progression. Most supervised exercise sessions are conducted by Dana K. McDaniel Cancel, Lead Supervised Exercise Trainer, under my planning, direction, and on-site supervision.

During a supervised session, we can see how you move and how you respond while the work is actually happening.

We can change the exercise. Change the load. Change the repetitions. Change the range of motion. Change the way the movement is performed.

Every supervised session is recorded, including the exercises, loads, sets, and repetitions, so progression is based on what you actually did.

Home exercise has its place. But when technique, loading, and progression need closer attention, there is real value in working in a purpose-built strength-rehabilitation facility, with the equipment to match the exercise to the person and progress it as their ability improves, while someone is there to watch, coach, and adjust the work as it happens.

The goal is more capability, not more appointments

I do not believe the purpose of care is to keep you coming indefinitely.

We should know what we are trying to accomplish.

That might mean being able to sleep without being awakened by pain. Sit through a workday. Walk farther. Press overhead. Return to golf. Start lifting again. Run. Squat. Work in the yard. Travel. Train hard.

There is no preset number of visits.

We look at whether pain is becoming less limiting, whether movement and strength are improving, whether you can tolerate more of what matters to you, and whether you are becoming less dependent on this office.

End the current episode of care when the job is done. We will be here when you need us again.

Your first visit should move you forward

Before your appointment, I personally call you to discuss what is going on. Every new appointment request receives that call within 24 hours.

We schedule one hour for the initial visit so there is time to hear the history, examine the problem, review relevant records or imaging, understand what you are trying to get back to, and explain what I find.

You will know what I think is going on and what I recommend doing about it.

You also receive a written Clinical Evaluation Report within 24 hours, at no additional charge. It records the important history, examination findings, diagnostic impressions, and recommendations. It is yours to keep and share with your physician, surgeon, or anyone else you choose.

When the findings support beginning treatment, treatment can begin.

When imaging would help clarify the problem or change the plan, I can order it. And when another specialist needs to be part of the solution, I can help you make that connection.

The examination matters because it gives us a reason for what we do next.

What if you have already tried treatment?

Start fresh.

Previous treatment not producing the result you hoped for does not tell us why the problem remains.

Bring any relevant records or imaging you have. Tell me what has been tried, what helped, what did not, and what you still cannot do.

Then we work from what the current findings show.

You do not have to arrive with the right diagnosis.

You just have to tell me what is hurting, what is not working, and what you want to get back to.

Who comes to Performance Sport Care?

People from Walnut Creek and throughout Contra Costa County come here for musculoskeletal pain and injuries that are interfering with the way they want to live.

Some are competitive athletes or lifters.

Some exercise because they love it.

Some want to remain active as they get older.

Some simply want their back to stop interfering with work, their shoulder to let them sleep, their knee to tolerate stairs, or their body to feel dependable again.

You do not need to be an athlete to be cared for like one.

Frequently asked questions

Do I need to be an athlete?

No. Care and rehabilitation are matched to your condition, your starting point, and what you need your body to do.

For some people that means very light, precise exercise. For others it can progress to substantially heavier loading. The goal is not to make everyone train like an athlete. It is to apply the same seriousness to helping you regain the capability that matters to you.

What happens at the first appointment?

You have time with Dr. Cancel to discuss the problem, what you have already tried, and what you want to get back to. He performs a functional and orthopedic examination, reviews relevant records or imaging you bring, explains the findings, and recommends a plan.

One hour is scheduled for the initial visit. You also receive a written Clinical Evaluation Report within 24 hours at no additional charge.

Will I be treated at the first visit?

When the findings support starting treatment that day, treatment can begin at the first visit.

If imaging or another medical opinion would meaningfully change what should happen next, Dr. Cancel will explain that and help you take that next step.

What if previous treatment did not help?

Come in and let us look at the problem again.

Bring relevant records or imaging if you have them and tell Dr. Cancel what has already been tried. The goal is to understand what the current findings show and build the next plan from there.

What kinds of treatment might be used?

Depending on your findings and goals, care can include chiropractic adjustments, manual treatment, assisted stretching, specific exercise, and supervised progressive strength rehabilitation.

The mix is individualized and can change as you improve.

Who conducts the supervised strength rehabilitation?

Dr. Cancel develops the rehabilitation plan and directs its progression.

Most supervised exercise sessions are conducted by Dana K. McDaniel Cancel, Lead Supervised Exercise Trainer, under his planning, direction, and on-site supervision. Each session is recorded so Dr. Cancel can follow the work and its progression.

Can Dr. Cancel order imaging?

Yes. When imaging would help clarify the problem or change the plan, Dr. Cancel can order the appropriate study and use the results in determining the next step.

How long will I need care?

There is no preset visit count.

Care is tied to what you are trying to regain: less limiting pain, better movement, greater strength or tolerance, and the ability to return to the activities that matter to you without depending indefinitely on the office.

What is the Clinical Evaluation Report?

It is a written record of your history, examination findings, diagnostic impressions, and recommendations.

Every new patient receives one within 24 hours of the initial evaluation at no additional charge. It is yours to keep and share.
