May 26, 2025It’s always a pleasure seeing Dr. Pugh for my daughters medical needs. She is kind, actively listens, our daughter absolutely loves her (which has never been the case with prior providers, she was always fearful of the dr’s office). Dr. Push has been such a blessing to us as a family, she is part of a cohesive team for our child and we all love & respect her so much.

Apr 24, 2025Dr. Pugh is amazing! We love her.
Apr 23, 2025We love Dr. Pugh. When our first was in the NICU every doctor that saw we saw Dr. Pugh spoke so highly of her! We trust her completely with our children’s care! She got me through the anxiety of a newborn after my first was born and she knows each of my children so well now. We adore her!
