I was very impressed with how everyone treated me at this office. The person I spoke to on the phone to make the appointment was very friendly and got me in to see the doctor as soon as possible. When I arrived for the appointment, the lady at the front desk greeted me with a smile and she was very respectful. Even while I was in the reception area, the staff that walked through said hello to everyone and they were pleasant. Also, I was very impressed with the doctor, I felt like he really listened to me, and he was very thorough in addressing all of my concerns.

My pharmacist called to see if one of the two prescriptions that the Dr recommended could be changed to one that was accepted by my HMO, instead of one of the two he prescribed that was not. He still hasn't returned her call, to my knowledge. Could you see that he does? Thank you so much.

Marlon may have been one of the best Doctors I have ever experienced. I felt heard and he seemed to genuinely care about what I was going through and wanted to find a solution. I didn't feel rushed and I left feeling at ease.
