There are two LLMDs in western PA, and they're both in Hermitage (practically side by side). They're Dr. S. Chandra Swami, MD and Dr. Joseph Joseph, MD (yes, that's his real name).
The next-closer female Lyme doc is in western Va.
I highly recommend Dr. Swami (Dr. Joseph can only see adults, but Dr. Swami can see both adults and children).
