August 9, 2025Wynnie D.Verified patient
Doctor is nice. He examined me thoroughly, answered all my questions and educated me on what supplements to add, since I became vegan 2 years ago (Vitamin B12 and Fish Oil). He also advised me to stop Centrum 50. I used to see him when he was part of another practice 20 years ago. Enjoyed catching up as well!
August 7, 2025Pradeep A.Verified patient
Office confirmed my appointment Monday for Friday morning. At 4 pm on Thursday, they called to say they cant see me nor can they honor zocdoc bookings. Absolutely unprofessional, poor mannered, and reprehensible behavior displayed a health care office in breach of their own stated professional ethics. Not enough diction exists in the English language to accurately convey how deceptive and unprofessionally thus office treats its patients. I would grade them an F but that would be too kind
June 20, 2025Salman C.Verified patient
Dr. Rajan is very knowledgeable and has a good bedside manner. He works with you to develop the best treatment plan for your specific medical situation and takes your input into consideration. This is a small office, appears to be one doctor and a couple of office staff, this can be a benefit, or not, depending on your situation and what you are looking for. Overall, I would recommend Dr. Rajan to others who are looking for an internalist and I plan to continue as a patient.
June 18, 2025Aaron A.Verified patient
The Provider appeared knowledgeable . He was able to manage my pain appropriately. He also provided the correct referral. Overall, I was satisfied
June 18, 2025BEATRICE A.Verified patient
His schedule isn't synced with Zocdoc at all. Do not schedule an appointment on Zocdoc and show up expecting to be seen. You'll wait for an hour before he tells you he didn't know about your appointment.
June 3, 2025Phillip M.Verified patient
My first appointment met & surpassed my expectations.
He prescribed lab work and told me exactly where to get it done immediately near by.
And I booked the next appointment for 5 days from now..
