As stated before getting appointment scheduled when needed is difficult due to understaffing nurses there are excellent, but they are often double booked and I feel more staff needs to be employed

I truly appreciate the time that was spent with me to review my personl record keeping and disucssion of my symptoms to find the root cause of the issue I was there for rather than slapping a generic label on it

A wonderful specialist who is knowledgeable in his field of practice. He has taught me a lot about MCAS and has politely corrected me when I have been wrong. He stood up for me in his clinical notes and continues to be patient with me as we navigate MCAS due to Dercum's disease together. I appreciate Doctor Regula very much.

The only issue is location. Always concerned about parking and if you are not used to downtown area it is not easy to drive there. I have read reviews from patients unable to find parking.
