Starts at the front reception... Great attitude, nice and comforting. Doctors, nurses and staff were also great! Listened to my father.

I would not recommend Diablo Valley Oncology as an employer. My time there was, unfortunately, the…read moreworst experience of my professional career. I encountered an environment that was unprofessional and lacking in basic respect and kindness. Despite my ability to work well with a wide range of personalities and teams, I was met with hostility and poor treatment by members of my department. I believe everyone deserves a workplace culture rooted in mutual respect, and that was not my experience here. That said, I walked away with an important lesson: some situations are not worth fighting for, and protecting your own well-being must come first.

Dr Matthew Sirott, Mariya Ryazantseva and the rest of the staff have been awesome. I give them…read moresooooo much credit for extending my wife's life to over 4X what her old doctors said she'd have a when first diagnosed(8+ years vs up to 1-2 years). This is such a difficult job, dealing with patients who quite often won't be around too long, but the nurses, assistants and doctors all tried everything that my insurance would approve. There were a lot of times that treatments or procedures were denied. My wife's cancer was vicious and aggressive. She tried every probably every chemo or immunotherapy on the market, did radiation multiple times, did infusions, had surgeries, and they always did their best to keep her truthfully informed, and keep her spirits up, even when the news wasn't good. Now my wife generally hates going to the doctor, but a trip to Diablo Valley was more like talking with friends for her. Now I will say to ask questions, and get all copies reports for yourself, so you can go home, and read and learn about what is happening. I think it was difficult doing this, but made everything make sense about what was happening. When you have a little knowledge about your treatment and conditions, the decisions are much easier to make in my opinion. I will miss my wife more than I can explain, but I truly believe they did their best to take care of Jerusha. Rest In Peace.
