Dr Lozanov has been treating my family for upwards of 10 years. He is a genuinely kind and thoughtful person. He is a wonderful listener and unlike most doctors I’ve encountered he will spend time with you and even research your issues after you leave. Even though we have moved to Santa Rosa we will still go back to Petaluma for all our medical needs. Thanks, Dr. Lozanov for caring!

Dr. Nikola was my doctor when I was in North CA for a few years. My full name is Sameer Khanwalker. He is a marvellous doctor whose diagnosis is very accurate and treatment is great. He is also a very warm, friendly and courteous doctor. I have not found another doctor like him since I moved out of CA.
