Dr. Chester

Before joining Dr. Lornell Hansen’s team, Dr. Chester worked dual roles 21 years as a family medicine physician at McGreevy Clinic (now part of Avera) and also a flight surgeon for the SD Air National Guard.

A native South Dakotan, Dr. Chester’s career path didn’t begin in medicine. After graduating from SDSU with a degree in mechanical engineering, he moved his young family to Michigan and worked in automotive engineering for six years. His “itch” to go to medical school and be closer to home brought him back to USD School of Medicine. He completed his family medicine residency in Sioux Falls before joining McGreevy Clinic.

Considering himself a “local,” Dr. Chester grew up on a farm north of Parker, SD. He and his wife Mary have been married 34 years. They have three grown children and six grandsons with number seven on the way.

Flying is a special passion and a hobby he shares with his wife.

Dr. Chester joined Physicians Vein Clinics in April of 2019.

“It is a great small but growing business atmosphere. Because the work is procedural, hands-on and visual, it fits my skillset; but I also like viewing every patient from a big picture standpoint.”
