Although I believe Dr. Gryniewicz is a great doctor her scheduling practices & staff are less than desirable. I have seen Dr. Gryniewicz for more than 10 yrs but my most recent experience was horrible. Her wait time for an appt. is 2 months, so I waited. Unfortunately I had a mandatory meeting come up at work during my appointment time. I asked to switch my appt. from morning to day & was told I'd have to wait another two months...Horrible customer service & NO appreciation for patient loyalty.
