My Doctor Michael O’Neil is great he takes the time to talk to you and explain everything with details he’s awesome very nice personality ! Very happy and enthusiastic. Hi Im doing this review today 03/27/26 my husband is helping since I lost a lot of my concentration and memory since My accident that I fell last year, march into a drain hole, it has been a night mare it was horrible and I told Doctor Michael O’Neil I was in a lot pain all bruised purple hematoma’s in my legs everything hurts when that happened, he said you’re a fine no worries that day was march 21 Friday and he told me to go back to work on Monday I said are you sure? He said yes, I was case manager nurse aide he didn’t care he didn’t even look at my legs or send me to an orthopedic or specialist to check me better!! Because of the extreme pain I went to another doctor I have neck and head issues my left side knee and right knee was hurting so swollen and my hip are still inflamed my shoulder has a tear 3 and eventually need surgery. Was it so hard to find another doctor ? thanks to you so irresponsible I have migraines my body was bruised for months and the worst part is I can’t go back to work I’m living with this chronic pain I could be dead. so I don’t understand why we have doctors if they would not gonna help us ? I’m so disappointed very sad no empathy that day he was in such rush I decided to stay quiet no to write anything but after talking to nurses they told me woww what kind of doctor do this not fear let’s be kind with others my life change so badly life is not only money or rushing thank God i find a great human doctor he’s helping me!

I chose this doctor for a virtual consultation based on his reviews stating he was kind and generous. Unfortunately, that was not my experience. While I understand that my condition was difficult to assess via a virtual consultation, he did not show any genuine empathy or interest in helping me resolve my ailment. I left our consultation feeling dissatisfied and disregarded. Now I'll have pay another doctor to get the proper care I deserve.
