I’ve been with this doc over 20 years. She works hard for her patients. I have complicated health issues and she does research to help me. She is kind and listens to you. She spends time to explain diagnoses, treatments and medications. I love her.

I go in every 5 weeks for Asthma shot and I could not be any more pleased. I have seen many drs and I feel that she is the best. She is very concerned about you , how you are feeling knows you and what you are there for. This doctor is amazing.

She is an amazing Doctor. Before I was sent to her I had several missed diagnosis but she had my Eosinophilic problem solved in just a few visits. I appreciate her so much.

Dr Subramanian is absolutely the best! I've never had a doctor take care of me the way she does! She's always patient and kind, always puts her patients first! She even called me over the weekend with my lab results! I really don't know if i would be here without her!

40 years chasing a diagnosis. Dozens of doctors. She found it on the second visit. Can’t recommend highly enough.

I’ve been with Dr Subramanian for 20+ years. She’s the only allergist who was able help get my allergies under control. I like that she treats her patients as individuals and goes the extra mile to do research for you. At every visit, she will say, I was thinking about your last visit and did some research. Let’s try this…. I really appreciate that about her. I would not go anywhere else.
