The technicians were wonderful, as always. The wait time was 30 past my appointment time. Also, appointments are very hard to get, especially for a morning fasting test. The facility at Post St could certainly use one or two more techs working there.

The staff here are top notch. I think they should hire an intake receptionist to deal with the administrative part of this process. Great service once I got in.

In and out quick. Had a morning appointment and arrived before 8:00am. Most folks were walk-ins and a few had already gotten in line by 7:50. Thankfully with an appointment I was the first one, there was about 8 people there after already so definitely would’ve been a long wait without one.
