"Love Dr Sief and I loved it when Dr Joyce was his PA. I do not like his new assistant Kate she is very controlling. All she wanted to do was run test and I’d already had run test and knew what was wrong with me. I called to get prescriptions refilled, she would not refill them so she started my cycle illness all over again. I have finished my prescription And I was feeling better when I tried to get my prescription refilled. I started my sickness all over again got dehydrated kidneys messed up again and now I’m gonna have to go see my kidney doctor and it’s all because she wouldn’t refill that medication and I know that’s it because it messes up my kidneys because I get dehydrated , see yes but I will not. It just said denied didn’t say why."

"The doctor s and nurses performing the procedure were terrific ,I have zero qualms with them. However they're answering service and returning calls us horrible! I've called back twice the same day they left me a message while I was at work. They're always on lunch for 2.5 hours (supposed lly 11am -1pm but whenever I called back I STILL cannot get them to return my call or get ahold of a person with my results) Please do better and I'd give ypu a 5!"

"I don't know about the other doctors here, but so far Dr Oliver has been great and figured out what's wrong with me. Everyone else I've dealt with here has also been great, even though it seems like they're always busy."

5.0 Review from S.H. Source: Google Jul 01 2018

"I have been a patient of Dr. Oliver's for well over 13yrs. He is an absolute delight, informative and educates me on any/all aspects of my auto immune diseases. His bedside manner is superb and spends the time needed to listen to my needs/concerns. I am a cash pay patient, and unlike many docs I have seen, Dr. Oliver is aware of that, helping me get treatments and meds at the most cost efficient way. If anyone is considering TDDC Dr. Oliver is the way to go. Some of his staff can be a bit "testy" but in my opinion its worth it because Dr. Oliver is worth those that may be having a bad day."
