Marissa Opilas, D.O. 350 John Muir Parkway, Brentwood, CA 94513

"She was about one half an hour late. But she did apologize and was very friendly and not in a hurry. She really cares and shows a true interest in one's well being. I would recommend her to anyone!"

"Dr.Opilas is a great listener and I never feel rushed through my appointments. She is open to my suggestions for my health care and we work very well together getting the right Dr.’s for our team. She is patient and understanding while explaining in detail our next steps to recovery. I’m so glad I have Dr. Opilas on my team."

"I had a wonderful experience with Dr. Opilas. The office is clean and employees are very friendly. Dr. Opilas was very caring and thorough as I was a new patient. I am so happy to have been able to see her and will continue to have her as my Primary doctor."

"Dr. Oplias is an extraordinary physician. She listens carefully and compassionately. Dr. Oplias is also very thorough. Her exams are alway from head to toes. She works collaborative with her patients to arrive at a solution to any problem. If she is unsure of a treatment plan, she will refer her patients to the appropriate specialist. Unfortunately, the Sutter Foundation changed their contracts with my health plan. They no longer accept HMOs. As I cannot afford a PPO policy I had to give up Dr. Oplias as my PCP. I sobbed when I had to tell her it was my last visit…….."

"She is an amazing doctor. Taker her time and really listens to my concern. Always makes sure I feel she’s advocating for me and helping me make educated choices regarding my health. And she’s amazing with kids 6 and older. So lucky I found her!!"
