I've been going to Dr Ricigliano for over 20 years. I've been lucky for most of that time to no have any health issues so my visits were always pleasant and quick. However, in the last few years I've been experiencing some health issues and the care thats been provided has been disappointing. The last few visits have been focused on putting me on medication vs finding the root cause of whats going on and treating it from that perspective. I explained what my goal was and that was blown off with no consideration and response and approach was more medication and come back in 6 months to yet again keep me on medication vs finding the driver of health issue. I clearly explained I am not looking to be pill farmed and goal is to find out whats happening and come up with a plan to get back on track without relying on pills. And now, after getting lab work and having a scheduled appointment to go over I get a call last minute after I received an appointment confirmation call that he will not be in office and I could be rescheduled to the end of February. Well, there's no need to reschedule. I will be switching providers today. I'm done with giving this Dr free money.
