Our Story


MAC Physical Therapy Group was founded by Peter MacDaniel in early 2016 to provide the highest quality treatment for his clients by individualizing treatment to allow for a quicker recovery back to life, work, exercise or sporting activities that they love doing. Peter had worked in a variety of clinics before opening MAC Physical Therapy Group and felt they all lacked a way of linking the rehab process back to competition or exercise in the gym. We believe that your treatment needs to come full circle by combining both physical therapy and fitness programs. MAC Physical Therapy was opened to bridge this gap and help clients reach their maximum potential by treating pain, optimizing movement and preventing further injuries through physical therapy treatments.

Why Choose MAC Physical Therapy Group

From your evaluation and every follow up appointment thereafter, you will see the same physical therapist. The treatment plan created will be individual to you to address your specific goals and help you heal from your injury. We believe heavily in educating our patients and what you do outside of the office is as important as inside the office. Every aspect of the treatment that is to be provided is unique to you and no two people are alike, therefore no two treatments are the same.

We strive on providing a higher level of care then you are used to getting with individualized treatment, modern techniques, and attention to detail through each phase of the rehab process. We believe that this higher level of care is what should be expected by you when seeking out a physical therapist. We schedule appointments every 30 minutes, so you will be one on one with your physical therapist during that 30 minutes to address all questions and concerns while receiving treatment.

If you are skeptical if physical therapy can help you with your pain or have been to physical therapy and been disappointed, please reach out to us as we know you will be happy with your treatment here.

Our approach to treatment will address the cause of your symptoms. We will help to manage your pain while optimizing movement and performance of your body to heal better and prevent re-occurrence. We like our clients to leave physical therapy much better then they were even before their pain began.

What our clients Say

I had foot pain in the arch of my foot for years, and tried every home remedy out there.  I got a recommendation to see Dr. Peter MacDaniel from a former client.  Pete fixed my foot in about 4 months, and I no longer have issues.  He is amazing at assessing and fixing pain.

This is the most progressive group ever led by Peter. He is way ahead of the industry standard curve. His exceptional skill helped me immensely. I am forever grateful.

Cat M.

My daughter has been working with Pete MacDaniel as part of her recovery from a torn and surgically repaired ACL. She started training with him immediately after surgery and has worked with him the entire time through her recovery and her return to the soccer field. Her continued training with him has made her stronger than ever. His expertise has helped her to gain overall body strength and she is well positioned to successfully and safely  continue her pursuits as a soccer player. Thank you Pete!  She would not be as strong as she is today if not for working with you.

Cindy B.

My son developed sudden significant back pain, likely due to rapid growth and trying multiple sports.  It bothered him enough to get an xray, and when that looked clean we were referred to MAC Physical Therapy to get some physical therapy. Peter was able to quickly find the issue quickly after a series of exercise and maneuvers, and gave my son creative, dynamic exercises to correct several imbalances of muscle strength in his neck and upper back.  He explained everything to my son in a way that was easy to understand. After a few weeks of PT, he was pain free, had better posture in his neck and shoulders and had a new awareness and list of exercises learned from Peter that he continues to practice.  Thank you MAC Physical Therapy for such a thorough, positive and educational experience!

Ro K.

I've been with Dr. MacDaniel for roughly 14 weeks. In this time Dr. MacDaniel has not only increased my strength but also educated me on the proper care post tommy john surgery.  His extreme knowledge of physical therapy and his care for is patient is paramount and at the forefront of his practice. I've recommend Dr. MacDaniel to anyone in need of physical therapy and will continue to be a patient of his long after my arm care has been completed.

Adam C.

I've been treated by Dr. MacDaniel for my knee, shoulder and back, each time my experience was great. After just a few visits I felt like a new person. Pete is very well educated along with professional and compassionate; he explains everything thoroughly. I have seen him work with patients of all ages and was equally impressed. I highly recommend him.

Lynn B.

Peter has been taking care of my shoulder since my rotator cuff surgery almost one year ago. I've had a very successful recovery and can continue to teach and train thanks to him. I have lost track of how many times I have walked into his office in tears because of pain and walked out feeling like a million bucks! Thank you for taking such good care of me
