Over the years, I have had the privilege of collaborating with patients from all levels of society, guiding them through some of their most challenging and rewarding moments. For the past decade, I have served as a Family Nurse Practitioner (FNP), and I obtained my master's degree from the University of Cincinnati.

I am deeply committed to creating a safe and supportive environment where every patient feels heard, respected, and cared for.
