This provider is the worst provider I have ever seen in my life. She has no bedside manner. She does not care about her at all if you’re in pain at all or need anything done she won’t help you. She will pretty much just tell you to suck it up and surgery you can’t help you there can’t help you and then leave you in the office on the door face while calling you and the office manager is not better she came in after her happened answered the provider side and basically taking me out of the office. There’s nothing they can do mind you I’ve had a full tear and both shoulders for two years and have been getting injections and now all of a sudden they won’t help me because she doesn’t like injections or medication. She wants to do surgery on everything. This office is horrible. I will never ever go to this office again. Do not go here if you want help please take my advice. This is not the first chance I’ve given this doctor or this office. This is their fifth chance and every time bad!!
