About Me

Why I chose to pursue a career in healthcare:

With my background as a Research Assistant, as well as a Medical Transcriptionist, I was drawn to the idea of a career in healthcare. Healthcare professionals can make a positive impact in people's lives. We work in a multidisciplinary team, which fosters camaraderie and a sense of belonging. I like that I'm able to give back to our community that welcomed me with open arms. I never stop learning. Continuous advances in our field keeps me on my toes and helps me keep up-to-date on the newest technologies, which in turn enables my patients to receive the best, state-of-the-art care.

What I want my patients to know about me:

As a PA State-Licensed, Board-Certified, Genetic Counselor working in the Prenatal/Preconception field, I enjoy helping patients who are going through one of their most significant life events. Being a mom, empathy comes naturally to me and I'm honored to be given the opportunity to support you during your journey. I'll strive to explain complex Genetic concepts and help you make informed decisions that are best for you and your family. I shall respect and support your decision, whatever it may be.

What I do when I'm not seeing patients:

My husband and I love traveling, both within our beautiful nation and internationally. We are at 32 states and counting! We have a blended family that includes four adult children and a fur baby. We love playing board games, which brings us closer as a family. I love gardening. Nature walks help me stay grounded.
