Very friendly office. Dr Shirk actually took the time to listen to my concerns, started treatment the same day. He explained my condition and gave me details of a treatment plan. I am very pleased with my care!

I had a slight back injury over the weekend and was able to get in with Greg first thing Monday morning. He was busy but took his time and did some ultrasound and adjustment. I appreciate his thoroughness and professionalism!

Dr. Shirk is very professional and friendly. He adjusts my back and shoulders very well. We have used Acute Care for years and would recommend him to other friends.

Calm, experienced and professional practice; they've never tried to sell me any of the pseudo-wellness products or subscriptions other practices do. They always have good ideas when I ask for a recommendation for shoes, seating, etc, but aren't pushy. They're also great when life happens and I need to change an appointment, etc. Would recommend to anyone.
