Go see her! She is SUPER smart at what she does. I was referred to her by another BJC Doctor and I'm so greatful. She found my issue in the time of my visit and it is now in the process of being treated. Others didn't care or didn't try to help like she did. Staff is super nice.

I have severe allergic rhinitis. I also have an autoimmune condition where my nasal passages grow shut. I went to WashU foremost allergy doctor and after surgery and 2 years he said he couldn't do anything more for me. I had to sleep sitting up for years because mucus was so thick I couldn't breathe. My GP referred me to her in 2001 and I won't go anywhere else. Will pay out of pocket. She helped me breathe again.Willing to do research to help her patients. Trust her with my life

Dr. Subramanian seemed to be a very competent Allergist and was able to see me right away, however her one of her office staff, Regina (Gina) made it very uncomfortable for me to call the office. She is VERY rude and made it to where I did not want to contact the office and am now going to stop Dr. Subramanian just for the fact that the office staff was terrible.
