“Dr. Mahajan was a breath of fresh air… my last primary care provider was one in an office of many, and aside from the first visit, never saw them again. I don’t get sick often so typically I’m only going once a year for an annual physical, so never actually seeing “my” doctor was an annoyance. I found Dr. Mahajan’s office staff friendly and welcoming. Office was clean and easy to find. Dr. Mahajan had a great bedside manner - friendly, personable, asked a lot of great questions. And I didn’t have to wait around forever. The only detractor over my last physician is that they had an in house phlebotomist and Dr. Mahajan did not, so urine test and blood work had to be outsourced. But they made that process (an order to LabCorp down the road) quick and painless; would take this slight inconvenience over my last doc’s office any day of the week! Highly recommend.”
