Dr. Mark S. Penner, DO, San Jose CA

Excellent caring physician! Dr. Penner is very knowledgeable, kind, and truly advocates for his patients. He allowed me the necessary time to address all of my concerns, and was very conscientious and extremely vested in my care. He explained my condition, results, and multiple medical modalities for follow up. I rarely write reviews, but this doctor deserves an outstanding one. I have to say that lately I have had a few bad encounters with “speciality” doctors. Dr. Penner has restored my faith that there are excellent physicians out there who truly go above and beyond for their patients!
