Waldorf, MD |
This office consistently stacks appts. On three occasions I have arrived on time for my appt only to learn there are more than 10 people ahead of me. This latest appt I waited 1.5 hours. I was so thankful to be seen I didn't argue. When I was finally seen the doctor was rude and utterly annoyed. He repeatedly responded that he had "too many patients" for my concerns. He was so rude I had no choice but to leave w/o being seen. He would not refund my copay. AVOID!

Dr. Osia is very courteous and kind. He analysis of my health is thorough. I love that he breaks down my diagnosis every visit and he patiently sits to discuss the outcome of how to improve my health. His staff is not always as friendly as I would like them to be. They can sometimes play too much around the patients. The office could improve in this area. I completely trust Dr. Osia as my primary care physician. He is a profession and the very best doctor that I have ever had in my lifetime.

He talks alot about himself. Very unprofessional and rude. I would not suggest anyone visit. They want you to value their time by implementing a $40 miss appt fee, but have you waiting an OVER an hour for an scheduled appointment. one receptionist is horrible at appointment setting. She should stay doing intake and vitals.. very disgusted. Will NOT return..
