I visited Lansing urgent care on September 15, 2026, and they placed a generic referral for GI issues due to my GJ tube use. Today, September 16, I called to follow up and was put on hold for 10 minutes before being transferred and scheduling an appointment for tomorrow, September 17, 2026, at 2 pm. This place has awesome communication skills
