This doctor and his staff are amazing! His low low prices are unbelievably low but you receive above first-class service from a wise doctor who Really listens to your problems, then he talks you through a solution in plain words. He didn't rush me through my visit (like most doctors) and he found a solution that fixed my issue. There was no long wait (like at a regular doctors office) they saw me right on time and the doctor's staff were more than just professional, they were actually friendly. After my visit I had a quick question that was unrelated to my medical issue and someone there was a true angel and quickly picked up my call and answered my question in a most pleasant way. Just try this doctors office one time and you won't go anywhere else. (I tried to think of negatives so people don't think this is a fake review and all I could come up with was that they're not located in a huge multi story expensive cement doctor$ office building but in a smaller "old-school" doctors office, like it used to be with all doctors. But when I actually think about that, I see it as a positive. It's a more friendly building... for a more friendly, and affective, doctors office.)

Dr Konstantin is the best! This man has been there for me every time I've needed help without fail. His Mom Mrs Konstantin is an angel and I can tell you that none of the apple fell far from that tree.

I went to Concentra, and after waiting for 2 hours, I realized I needed to wait another 2 hours. I decided to leave. Luckily, I found Dr. John, and it took only 15 minutes to complete all my physical exams. Highly recommended!

Truly one of the best doctors for primary care in California.. Over the course of the past 5 years, I have been to 27 doctors of every variety you can imagine to help me with my neurological disorders.. Dr. Konstantin is in my top 3 for his attentiveness, compassion, insightfulness and understanding.
