I wish I had a better opportunity to explain how dedicated I am to finding a safe way to preserve bone.
- 5 out of 5 starsReviewed on 2/7/2026
She takes any anxiety out of the process of determining how to proceed. We are straightforward and candid with each other and thus, reach decisions based on facts that have been gathered. She explains choices with possible risks and probable outcomes. She teaches me so much and I can ask her anything. This comfort level has built great trust for me as she is invested in her goals for my good. She can also tell me to get going on exercise (again) because it will make a difference. I am... and it does! Thanks- I needed that!
