Dr Siddhanti is an excellent physician I drive an hour from Lithonia to Alpharetta Ga to see her. Her nurse, Ozzie, was also excellent today! Ten stars to both of them'

She's a good doctor. I like her very much. She answers the question. I wish she would volunteer a little bit more information, but she's exceptionally very good. I trust her. I like her. I like her manner. Thank you.

Dr. Sidd has been my rheumatologist for the past 15 years. She's one of the best. She's caring, thoughtful and professional. I would not trade her for no one else.

The nurse was exceptionally helpful, kind, and caring. I am so happy to find a near by good Rheumatologist. And, the lab is right there, a great and clean set up.

Front office staff could use more patient "interaction training"! Been a patient at Wellstar Avalon since moving to the area 4 years ago and this was my first encounter with any short tempered staff. This gentleman appeared agitated with any question regarding next appointment.

Dr Siddhanthi is great. Wellstar Rheumatology is significantly overpriced for self pay patients. All other doctors that I see for a 10 minute follow up charge in the range of $100. Wellstar charges $237. I will likely be leaving in response.
July 20, 2024
5
My only complaint is not against Wellstar but the lab company they use. Twice my blood work has been lost or not run. So for 6 months I have no idea what my kidney function is while on medication that can be harmful to the kidneys.
July 20, 2024

Very good at what they do
July 20, 2024
5
I feel we are kept in the examination room too long before the doctor comes in. It should be no more than 15 minutes after the nurse has gone through your paperwork and taken your vitals. Give the doctor 15 minutes after that not 30 or 45 minutes.
