"Very efficient experience! I received a text the day before instructing me on procedure when I arrived. Once parked, I texted that I was on-site, waited in the car, and in a few minutes was instructed to go to a certain waiting room. When I got there, a nurse was already there! Did my check-up, had my time with Dr. Castle, and then taken to the lab to do some blood taken for my physical.I swear I felt like Rip Van Winkle and I arrived in the future! I enjoyed my experience and would recommend to my friends and family."
