    Waiting room
    Alan C.

    Made an appointment online and arrived a little early. Check in was easy and they took me on time. Technician was professional and friendly. In and out in less than 15 minutes. Plenty of open seating at the time I arrived. Only negative was it took several days to get an appointment at the time I needed,

    I would have given a 5-star review if there was a 0-5 minutes wait, and honestly the wait was not that long at all! My appointment was at 12:10 I checked in at 12:07 I was called by 12:20ish I was out by 12:29 My phlebotomist was Gisel--she deserves 20 million stars!!! I've been dubbed a hard-stick by all whom encounter me. And I've been a little traumatized by blood draws because I've had experiences with people thinking I'm dramatic, and not believing I'm THAT much of hard-stick. Others have poked and prodded to the point of bruises left behind. Or they'll blindly poke hoping for the best. I've been passed on from person to person--the most I've had was THREE people try maximum pokes at one sitting. But Gisel was a doll! She didn't poke until she had a vein she was confident enough in. It was super quick and easy. She listened to me when I said I was hard-stick. She's the best I've ever had. Thank you, Gisel!

    It runs very hot and very cold here. Sometimes super smooth, sometimes the complete opposite. You have some incredibly warm and personal people and you have another that is brash and crass. It seems to go unchecked as it has been going on for quite a long time now. Place always seems understaffed. Quest is too cheap to pay a receptionist. tv is pretty loud / overbearing. Otherwise the place is great Parking is ok.

    This is a heroic photo of myself giving the woman who drew my blood a thumbs down .

    The other Quest lab in Simi Valley was unable to successfully draw blood after three attempts so I decided to try this office.

    so I give 5 stars for the techs. The quest in TO can never get my vein the first time but this one…read morecan. The thing is if you have to go in the morning before work or fasting and don't have an appt the wait is insane. I arrived 5 min before they even opened for the day and I waited an hour and 40 min. They take the walk in patients last but when they schedule like 5 appts every 10 min that gives no time for walk ins. I think they should book at least a little extra time for walk ins.

    Not a bad experience at all. I originally tried making an appointment online, but it looks like…read morethere were no available appointments at any of the quest diagnostics till next Tuesday (5days away) so I booked the Tues appointment but still decided to take a chance show up early in the day today and see if could potentially be seen as walk-in to test my luck. As luck would have it I walked in, put my name in the kiosk as a walk in around 11:30ish and only 1 other walk in person was ahead of me with 10 scheduled appointments to which the "wait time" was potentially anywhere from 30-60 mins etc and that was an IF. I sat down in the waiting area and they called about 5 people in while waiting and I saw a few people come out as they did so. That took about maybe 20 mins? Then I was called, so not to bad I really only waited 30 mins MAX as a walk in this morning My technician was nice and straightforward but felt bad she seemed a bit rushed but understandable I'm sure she sees a new person every 5 mins. As someone who is DEATHLY afraid of needles and typically faints when blood is drawn she was extremely gentle with me and I barely felt anything. I'm actually shocked how easy it went for me, then we finished after 5-7 mins and had to do a urine sample and done. My only minor complaint is there is typically a box in the bathroom or dedicated box for urine samples away from the Public so it's more private and disclosure however it looks like even after you do the sample you may have to walk back into the testing room while another patient is getting there blood drawn to place is on the box in front of them. It's just alittle weird but none the less not a bad experience, will come again.

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 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!

She infrequently answers emails and then complains if you send too many. She took my blood the first visit where she brought in her new puppy. She paid more attention to the puppy than me and then charged me $300 for the visit. Okay. Hopefully she can fix my issue. The blood work came back. The report showed I had pre diabetes, lupus and some other horrible disease. She said I needed her to interpret the findings. Then she gave me 20 vitamins to purchase and take every day! I'm still having sugar issues and my eyes going wonky. OH!!!! And she charged me for a telephone visit to go over these results. Another $300!!! I took the report to my GP. I was so freaked out!!! He did blood work and I was fine. No diabeties no lupus. No other diseases. Fast forward 6 months. And my sugar is still messed up. My eyes are still wonky. Sent her an email asking why my sugar is still messed up. She didn't respond. Sent another email. She responded with an appointment. Sent back that time didn't work. Never heard back. In my opinion and experience, if you have medical issues, this doctor is not for you. If you need help and communication with your doctor. This is not the one. I have never had a hormone doctor charge me for tests and then another charge to review them!!! $600 later and a whole lot of stress because of her blood tests, I still have a sugar issue and my eyes are still going wonky! I'll find a new doctor. I'm not recommending this doctor at all.
