Welcome from the program director

Congratulations on beginning the residency application process! Thank you for your interest in the PGY1 Pharmacy Residency Program at Memorial Regional Medical Center in Mechanicsville, Va., which is a short commute from the Richmond metropolitan area. 

Bon Secours Memorial Regional Medical Center is a 269-licensed bed community hospital that is a member of the Bon Secours Mercy Health system.
