I visited Concentra on Tuesday, 6/6/17, for a pre-employment physical and drug screening. No appointments were available, so I went for a walk-in around 3:45 pm. Wait time was minimal, and every staff member was very pleasant. Kari O., the professional who gave me my drug test, Hepatitis B vaccine, and blood drawing, was extraordinarily friendly and even funny. I expected this process to be boring at best and grueling at worst, but Kari O. in particular made it a positive experience. The doctor was also professional and kind. I was in and out within 1 hour.
