Comprehensive Wellness in Walnut Creek, California is a multi-disciplinary medical practice focused on building strong relationships with our patients to develop personalized treatment plans tailored to each individual’s unique needs. We offer services for the whole family — from pediatric and geriatric care to gynecologic and preoperative care—as well as a full range of therapy, aesthetic medicine, musculoskeletal health, and nutrition/weight management services.

relationship based

We are a medical practice based on relationships with patients, rather than production numbers and insurance company red tape. A practice where providers and patients can work together to create individualized plans of care.


Life can be complicated at times. We offer our patients unique alternatives—evening and Saturday appointments, home visits, telephone and video consultations—all designed to make it easier for you to access your health care.


As an independent practice affiliated with John Muir Health, we ensure that when you go to the hospital, all of your records, labs, test results, and other important health information are available to your care providers.


Our team crosses a variety of disciplines, allowing us to develop collaborative treatment plans that integrate internal medicine, therapy, women’s health, musculoskeletal, aesthetic medicine, and nutrition/weight management care.

From the minute I walked into Comprehensive Wellness, I knew I was in the right place! The front desk staff were so friendly and welcoming! Then, Dr. Parish and Dr. Seibert were such talented doctors with an excellent bedside manner. I had been having foot pain for months and a few weeks later I am ready to start running again! Thank you to the entire Comprehensive Wellness team!

Dr. Nancy Rolnik is great. I've seen Dr. Rolnik a few times, for a hurt shoulder and (separately) a hurt finger from waterpolo, and a pulled back from baseball. Dr. Rolnik is practical and thorough in examinations--one time she ordered an x-ray, but other times she deemed that not necessary. She does not over-prescribe. She gives good advice for both short-term pain-relief and performance, and also for long-term prevention. And she's friendly, non-nonsense, and dare I say fun (for a doc!).

I woke up with shooting pain down my right leg and barely able to walk. I called CW and was told to come see Dr. Parish within the hour. She diagnosed my issue, provided pain relief, had me see physical therapists within minutes. Dr. Parish is thorough, decisive, efficient, and effective. Highly recommend!

Brett has helped my family navigate a very difficult time. We also addressed my anxiety and depression and I can now manage both well. My husband calls him the "teen whisperer" since his advice about our children has always been spot on.

My experience at Comprehensive Wellness was amazing. I was able to have multiple appointments all on the same day. I could take care of physical therapy, botox, SculpSure and my annual physical in one place! The combination of everyone's caring bedside manner and professional expertise is perfect.

I cannot say enough good things about my experience with the Dr. Parish and her staff. She saved me from a life of pain. She or a member of her staff was available to me whenever I had a question or concern immediately. I am always impressed with how quickly she responds to me. Dr. Parish truly cares about me.

Dr. Parish's commitment to … coordinating all my parents various health care needs and painting the "big picture" is so refreshing and took a huge load off of me. She is truly a health partner and I cannot say enough good words about her and the people in her office.
