We love Dr. Nicholson! She's is always patient and attentive. She is very personable and seems to genuinely care about my five year old. She addresses all concerns both my daughter and I have. We couldn't ask for a better doctor!

Hands down one of the best doctors I have ever met. I have been through a lot of GI doctors with my condition and have a hard time trusting they know what they are talking about and will help me. This provider absolutely knew her stuff and had all the kindness and professionalism to boot! I rarely meet caregivers who understand the complexity of rare conditions. She is amazing!
