Dr. Davis and Dr. Grant are a well-oiled machine. They have been working together for 20+ years and are both board-certified nephrologists. Dr. Davis and Dr. Grant completed their residencies at the University of Tennessee Health Science Center, and joined forces in the early 2000's. Bluff City Vascular, formerly known as Interventional Nephrology was founded after both Dr. Davis and Dr. Grant recognized the need for vascular care without barriers. Both physicians wanted to provide a welcoming, safe, cutting-edge facility in the heart of Memphis that supports diverse patient populations with complex medical histories. 

Dr. Omar Rashad Davis is  from Kansas City, Kansas. He received his medical degree from the University of Tennessee Health Science Center, and completed his residency there as well.

He values encouraging his patients to live a healthy and active lifestyle, similar to the way he lives his.
