My experience with Dr Dimitriu was outstanding! His ability to listen and understand my situation resulted in overcoming sleep difficulties that had been plaguing me for years. I felt like he really cared and was very easy to communicate from the start.

After suffering for months not sleeping and being in a manic state, Dr Dimitriu was recommended to me and after a wait for an appointment I went with eyes wide open. Caring staff took care of me getting my meds squared away and getting me on track with when best to take them and what meds I shouldn't be taking. Within a few days I was sleeping an additional hour per night until I was sleeping 9 hours per night. I also found out I had sleep apnea that I dealt with. The attention I received from all staff proved caring and my needs were always put first. Dr Dimitriu and Lauren Varma are tops in

I came to California seeking medical help for an unknown, undiagnosed disease that I've been dealing with for 12+ years. My doctors at home had essentially given up on me and left me to fend for myself. There was no more empathy, no more concern. If they couldn't see it, it didn't exist. I will not get into details but I've lost 50 lbs. and a whole host of other daily problems. It was/is not a pleasant host of symptoms I deal with to put it mildly. I had the FORTUNE to meet with Dr. Dimitriu earlier this week. The first thing that struck me was his extreme compassion, concern and how he immediately
