    everyone was very friendly and caring. Very different (and better) atmosphere than previously used urgent care
    Love this Urgent Care Center. Will continue to use this Facility
    The treatment was excellent. The wait was a BAD joke.
    please have more than one doctor so the wait time is not that long.
    we had a positive experience given it was our first time. glad we didn't let the negative reviews on yelp deterred us from coming. the operating hours on weekends are a life saver when we can't access our primary care doctor. thank you for your sacrifices
