This is a welcoming and pleasant healthcare environment. The entire staff makes you feel valued. The office and procedure rooms are clean and well kept. Oj is always pleasant, professional and explains what he is going to do and wShow morehy. I was negligent about maintaining a set schedule and he reminded me every 6 months would be optimal for my exposure history. There was no judgemental tone. I made my 6 month appointment and now will be on schedule. Thank you…..

Joan H. • July 15, 2026

I was going to be charged twice as much money for this visit as what I was charged for a prior visit and was not informed ahead of time (no secrets policy prices were not disclosed) until I asked the staff to please double check with the doctor after the appointment. Initially they just said that prices had increased to double in a matter of months but had billed an office visit versus a 911 appointment by accident. The injection also didn’t at all resolve my cyst and may have made it worse. This happened the previous time I had a 911 as well which had been discouraging. So I have paid close to $120 to have a cyst remain unchanged and take longer to heal potentially. Both appointments I was also going to be charged for a full office visit until I asked if the staff could double check. Just a bummer of an experience this time and last appointment sadly and I hate to write discouraging feedback but that was my experience unfortunately.
