She's friendly and approachable, and checks back frequently to see if you have followed her explanations, stopping to provide more clarity.if needed. She is currently working with my nephrologist to determine the appropriate dosage of calcium for me, with CKD4 and osteoporosis.

She'd be a perfect 10 if appointments started on time, but she's absolutely worth the wait. She wants a total overview of my health, which I appreciate. I know that takes time. I've recommended her many times now to others.

This was my first appointment with her. She was excellent in every way. I couldn't have been happier with her. She clearly knew my history, listened carefully to me and answered every question fully. She understood who I was as a person and as a patient during this visit. I plan on recommending her to a couple of friends.
