I was very impressed with the service and care that I received while visiting the Inclusion Clinic. I felt like I was at home with the comfort and the genuine care that was given to me. I'm already sharing my experience with my friends.

My provider is awesome. I had major delay and hassle working with your on-campus pharmacy, however - and it was unfortunate because I was a new client after having switched from my previous pharmacy. But my first experience was very shoddy, beginning with the poor parking options on your grounds, to poor communication, to grotesque waiting times. I thought it would be to my advantage to have my pharmacy near where I receive care - but the subpar experience definitely made the case that your pharmacy services are not oriented to exemplary customer service or care.

Everything was great but my last minutes input about my 8 year old severe leg injury and ongoing nerve damage was not considered current medical condition.
