Dr. Obiora is an excellent listener and doctor.
Dr. Obiora is fabulous.
Needed a colonoscopy and referred to Dr. Aslan. During brief interview, he insisted that I also needed an endoscopy down my throat. I asked several questions and received no answers. He just kept insisting that I needed an endoscopy. I asked if I could have the colonoscopy and skip the endoscopy. He said well, if I didn't have it, I would be “required” to sign a waiver. Required?I found him to be a rather unpleasant individual. I felt increasingly less confident in him. For the first time in my life, I looked at online revie... read more
I have been Dr. Deroee patient for about 2 years now. I had extreme back pain because of nerves in my back that give me a lot of pain. Every six months I have my nerves burned. The procedure doesn’t hurt at all and once he is done the pain is completely gone! I have a bad knee that is crushed bone on bone. I need a total knee replacement but for my safety I have to shed some pounds. Dr. Deroee manages my pain which makes life so much better! The staff are amazing also. They go above and beyond to help me ! Everybody is so ni... read more
I was referred to Dr. Deroee for back pain that I had suffered with for many years. It was with his recommendations and treatment that I was able to get relief of my pain and return to doing the things that I enjoy doing without oral medications that gave little or no relief. I appreciate all his efforts and concern for my well being.
I was admitted to the hospital with severe case of valley fever. The assigned Dr. on call was less than stellar. Two weeks later I was begging to be released I then went to John Muir Walnut Creek and Dr. Callister and his associates took over my care while I was in a coma with the support of UC Davis. The difference in care was incredible, mostly in the treatment plan. I continued seeing Dr. Callister for a total of 4 years until I moved out of state. Finding another ID doctor to handle my case has been a challenge.
My husband scheduled an appointment for a routine colonoscopy consultation in May 2023. During the consultation, Dr. Rowe recommended an abdominal scan, which he underwent after the appointment. However, due to the inclusion of this additional test, the office did not bill the insurance as a routine consultation. Without sending us a bill, they automatically charged his credit card (on file) $215. He didn't know about the charge prior until he got the notification from credit card app. After numerous calls with both insuranc... read more
What a nightmare. I've been dealing with IBS and called here to make an appointment. I mentioned to the receptionist I had seen another Gastro (since they have a month 2 wait and who can wait that long??) and they weren't at all helpful (sexist old man who told me my symptoms wouldn't bother a man!). She then said that because I had seen someone else, they wouldn't see me for the rest of the year. What the hell kind of policy is that? Extremely rude and uncaring receptionist, she shouldn't be working in health care if she ca... read more
Recent visit was very short-about 20 minutes for a new patient. Dr. Yee acted like he had no time and only spent the 20 minutes because we had questions and he had to answer them.
