“Jill always listens to you”

Visited on November 9, 2024

Jill always listens to you. She doesn’t just look at labs and give cookie cutter doses She asks how you feel and if there are any residual symptoms that you may be experiencing. My protocol is dialed in and that is in large part thanks to Jill!!!

I always speak to Dr. Saya but his appointments were way out. Dr. Culkin was great to deal with and it was good to get a different perspective. Highly recommend!
