Mary Jo Wagner

Physical & Massage Therapist

Mary Jo Wagner is a hands-on physical therapist specializing in manual therapy including Myofascial Release, Strain-Counterstrain, Craniosacral Therapy, Muscle Energy and Massage Therapy. Her post-graduate training has been centered around Osteopathic Manual Therapy, and she has been in practice for twenty-eight years, running her own business for fifteen of those. Mary Jo has found success in working with a wide variety of patients and especially with individuals who have not responded well to conventional therapies for pain reduction. She has found that these manual therapies address systems of the body that are otherwise ignored. Over time, this neglect can cause significant negative changes in lifestyle. These therapies have been proven to increase the rate of mental and physical healing.

Mary Jo firmly believes in breathwork, meditation, and prayer to reduce stress, and she incorporates these into her sessions. She has a deep love for her work and helping others and she treats each patient according to their specific individual needs.

Charlie Rivers

Exercise Physiology

In working with the Windmill Wellness Team, my goal for you, the client, is to improve your Biomechanical Integrity. I can work with you to remedy, reform and redesign the way your body moves. Biomechanics is essentially the ways your skeletal, muscular and nervous systems all work and interact with one another under different conditions. As a practitioner, I evaluate your needs by examining your postural alignment and movement strategies. I also work with the other doctors and therapists of the Windmill Team to identify your overall wellness and fitness goals. Altogether, when we have a clear focus, I will work with you to help correct any behaviors, postures and patterns that can be injurious or limiting to your capabilities and capacity for optimal movement.
Based on need, I work with clients in three different formats:
Commercial Fitness
In this format I teach and work with reasonably healthy clients in a classic personal training setting. Training styles and equipment for this level will vary and range. Clients looking for increase in sports performance are common and typically respond well to this training.

Clinical Fitness
The goal of this training is to help the client bridge the gap between injury, rehabilitation and/or less than optimal movement patterns and move towards a more healthy, active and functional lifestyle. This level of training in done in conjunction with your doctor or physical therapist recommendations in mind and with a Corrective Exercise approach. Here, your alignment, breathing and breath control in both static and dynamic movement patterns becomes the top priority. Releasing restrictions, addressing strength imbalances, muscle re-education and kinetic awareness are all focus aspects of this training process.

Assisted Clinical Fitness
This is often a preferred method of addressing your needs. In this setting, I work with your doctor or physical therapist during each session. Together, in a team approach and by focusing on each practitioner’s area of expertise, you benefit from the knowledge and the hands-on experience of both professionals in real time. Oftentimes, your biomechanical concerns that would otherwise take several sessions to resolve, can be assessed and addressed in much less time.
