The San Mateo Orthopedic Medical Group has been providing outstanding comprehensive orthopedic care in downtown San Mateo for over 60 years.

Dear Patient,

Recently, some variables have evolved to where I sadly must leave orthopedics. It has been 22 years of servicing the community. I am having a hard time with this decision but feel it is the correct route. During the ebb and flow of my career, what has kept me going was the enjoyment of meeting, knowing, and treating all of you. I will miss the birthday songs, shared stories of the challenges of parenthood, moments of joking and laughter, and the quiet moments when we talk about a loved one being ill or passing.

My practice is closed as of September 15, 2026. To cover the logistics, your medical records and x-rays are still accessible. Almost all the records can be accessed through Epic by any medical service provider who uses the system. The office will remain open for some time to come, so please feel free to contact them for assistance, at the same phone number, 650-342-0854.

I am arranging for some individuals to be available for continued care. Please contact us for any updates on this. In the meantime, recommendations can be obtained from your PCP and insurance companies.

• Dr. Richard Han, MD, Burlingame, CA, 650-692-1475
• Dr. Marvin Lo, MD, San Mateo, CA, 650-658-7100
• Dr. Akira Yamamoto, MD, Mountain View, CA, 650-934-7111, specialist in Mako procedures
• Dr. Musa Zaid, MD, Burlingame, CA, 650-652-8700, specialist in Mako procedures
• Dr. Dirk Diefendorf, MD, San Mateo, CA, 650-347-0517

I feel like I am letting all of you down. I am sorry for this. I hope that during our time together I was able to give you comfort and understanding of your ailment and help maintain or improve your quality of life.

Sincerely,

Dennis C. Park, MD
