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…..
