Our administration Team

I moved from Queens, New York over 22 years ago. My first job was working for the IRS in Jan 1988, then I decided to work in healthcare, when I went to work for Elmhurst City Hospital in Aug 1992 as a Patient Care Associate OB/GYN. In April 1998, I ventured into a Private Medical office called Madison East Pediatrics, P.C. - New York, New York as the Manager/Biller. Then I moved to Florida in 2001 and started working for Medical Office Practices in Central Florida. Currently, I have been with Sand Lake Internal Medicine for 3 years as their Practice Manager and I also have my own billing business called Reliable Billing Services, LLC.
