“The only feedback is that the provider has a 5-minute grace period, but it took 30 minutes to see me, which feels unfair. Providers should arrive on time for their appointments just like patients do. Aside from that, she was fantastic and answered all my questions. ”

Overall very positive experience. Getting to the suite was easy and the receptionists were helpful and nice. The check-in and intake process was very simple and my wait time was approximately 5-7 minutes after check-in was completed. Meeting Dr. Viator was also a very positive experience. She is personable, kind, respectful and understanding. I felt valued, heard and am very satisfied with my level of care and the care regimen going forward.
