On Sept 14, 2025 (yesterday), my granddaughter visited this "'Urgent Care" after injuring her foot playing soccer. From the moment she registered, the staff were cold. Almost rude.

Then the nurse came to release her...without the Dr coming back to discuss her xray! She had to ask the Dr to see "the patient"!! Unacceptable!

Suite 300 is awful. Although my doctors are good, the check in staff doesn't respond to your arrival, smile, or in anyway try to be pleasant to patients. There are currently 16 cheap print outs taped onto the walls with warnings for complaining about service, disclaimers etc. The chairs are filthy, the wait is long, the staff acts annoyed at patients presence.
