Everyone was nice, acknowledged you quickly, it was only minutes before going in. The nurses were nice the one who started IV really did a good job. I love the small personal feeling you get here.

Dr Catinis was very pleasant and took the time to thoroughly explain my lab results during my appointment.

Overall is good ! The only thing I would say is that the waiting time for my endoscopy procedure was too long. It would’ve been better if I was given a later time to come in instead of waiting two hours. Other than that, everything was great and quick after the procedure.
