Rhoda

Practice Administrator
rhoda@ivfphoenix.com

Rhoda is a fearless advocate for those desiring to be parents. She joined IVF Phoenix™ in 2011 and has been vocal on our social platforms about educating around miscarriage and pregnancy loss. Having experienced recurrent miscarriages herself, she understands the profound grief and how one can feel a loss of control. Protecting a patient’s emotional wellness is paramount to not giving up on a dream to become a parent.

“Being witness to the process of seeing a patient get that first positive to finally graduating from the practice is a feeling that never gets old as we all know just how hard the road was to get her to this very moment.”
