    I went in for a test for a new job. Nobody in the waiting room and I was in and out in less that 15 minutes. Super fast!

    AAA+++ Doctor Rezai is Exceptional and Exemplary. My 1st, 2nd, 3rd and all encounters with him,…read moreand his staff here in Thousand Oaks who demonstrate an attitude of dedication. Effectivley and caringly incorporating professionalism, comunication and dilligence within the scope of Reception, Patient, Nurse, Doctor are the reason i said we are fortunate to have a facility such as Zai Health, i have accompanied my elderly mother on numerous occasions to Zai Health among others. Without being detailed i can tell you that Dr. Rezai evokes in an exemplary and down to earth manner relevant charachter traits that you might find essential in a good doctor patient relationship. Honesty, integrity, and concern for a patients own wishes and personal feelings, it seems to me are not trivial maters to Doctor Rezai or his dilligent well chosen team of associates. Even when the matter was serious and i brought my mother in, although, Doctor Rezai was not there at the time of that particular visit, it was not a great concern as i was highly impressed by the associate physician who was on duty. Dr. Rezai obviously is a man of who is understanding and skilled in discernment and it is reflected in his choice of asociates and office personnel Furthermore, i came to find out that others among my own close relatives also do use their services and were no less impressed than myself. For discussing medical issues or understanding test results regardless if they were originating from care at Rezai Health, i would not hesitate to consult with Dr. Mohammed Rezai or anyone part of his team. I see great evidence of a tremendous asset to our thousand oaks comunity as i see Rezai Health being established. This review is an expression of my heartfelt appreciation for all at Rezai Health.

    We were so excited that Dr. Rezai opened his clinic! Our son wasn't feeling great and kept tugging…read moreat his ears so we decided to take him to see Dr. Rezai since his normal ped didn't have any availability. We were able to get in quickly within 30 minutes of calling the clinic! The clinic is NICE! Everything is brand new and so well designed. It's not your typical medical clinic that's plain walls and cold. There's beautiful artwork (I wish I had gotten a picture) and every room has a screen that will show you X-rays, etc. Dr. Rezai and his assistant were great. His assistant took our son's vitals (even with him squirming everywhere). Dr. Rezai came in shortly after and lo and behold, he had a double ear infection. Dr. Rezai called in a prescription and we were able to pick it up right after we left the clinic. We will definitely be back again next time we need to see a doctor!
