Rex had seven years of experience as an emergency room (ER) registered nurse prior to becoming a nurse practitioner. 
After obtaining his family nurse practitioner degree at Walden University, he decided to specialize in cardiology in which he was mentored by Dr. Ramin Manshadi. He values education and currently is pursuing adult-gerontology acute care nurse practitioner (AG-ACNP) studies at University of Pennsylvania’s online program.


Dear Dr. Manshadi, "I wish to thank you for the work you have done to treat my poor heart. You identified the occlusion and did an excellent job in placing the stent. This occurred around coincidently with the birth of your baby boy but you put me at the top of your priorities and proceeded with treatment. Please accept my sincerest appreciation for your good work."
- M. Edwards, actual patient.
