Who do we see? What do we treat?

As one of the Denver areas most prominent resources for quality physical therapy, Wetzler Integrative Physical Therapy specializes in finding the root cause for your body's structural dysfunctions. Our treatments always focus on a whole-body wellness approach. While we work hard to offer state of the art treatments to help you feel better, we also focus on preventative strategies to ensure you stay better.


At the heart of our treatment is our total body evaluation, which guides us in finding the underlying malfunctions. Treatment sessions are one on one with a licensed doctor of physical therapy. Our therapists are highly trained certified manual therapists who are constantly furthering their education to stay up to date with the most current information and techniques available. Your treatment may include, manual therapy, education for an increased awareness of what is going on in your body, posture and alignment analysis, as well as possible movement and corrective exercises. We are happy to consult with any current or future health practitioners you may have about your background, care, and progress.


Physical Therapy Modalities: Among the foundations of our integrated approach to wellness are the fundamentals of physical therapy. These may include procedures such as ultrasound, laser light therapy, electrical stimulation, body mechanics, deep tissue massage, heat, ice, and medical fitness. 

Visceral Manipulation: At times, overuse of muscle groups, repetition of movement , injuries, strains or accidents can cause an internal pulling of organs and their attachments  that create pain or discomfort in muscles, connective tissue, or the skeletal structure. Using visceral (organ system) techniques, our therapists gently enhance the mobility and tissue movement of the organs, which decreases pain and promotes the body's natural healing process.

Craniosacral Therapy: This gentle therapy promotes the release of restrictions in the connective tissues that surround the brain and spinal cord. This light-touch therapy improves the central nervous system function, reducing the effects of stress and strengthens resistance to disease. 

Myofascial Release: Sometimes accidents, injuries or simply the overuse of muscles can cause muscle and surrounding connective tissue, or fascia, to become restricted causing pain and/or limited movement. This can cause chronic muscle or joint pain, spasms, or an internal misalignment of the internal body structures. Using a variety of gentle slow stretches, these techniques correct long-standing tissue restrictions. The outcome is decreased pain and increased mobility.

Manual Articular Techniques: An exceptional therapeutic process which restores free and comfortable motion to a painful or restricted joint. The process uses a direct, three-dimensional movement approach of timed soft tissue contraction/relaxation, which inhibits restriction within the muscular skeletal system.

Manual Lymphatic Drainage: This technique activates and cleanses the human fluid system to help the rhythm, pressure, quality, and direction of lymph flow. The body can then naturally and more effectively filter out toxins and assist the body in healing itself. Many patients find a reduction in swelling and muscle and joint pain.

Gail Wetzler currently owns our integrative physical therapy practice in Lone Tree, Colorado with over 45 years of experience. After receiving her initial degree in physical therapy, she pursued her first experience in acute orthopedic care at Hoag Hospital, Newport Beach California. Within 1 year, she became the outpatient clinical supervisor and thus began her journey and desire for continuing education in the science and art of human movement and function. She studied with Travell and Simons, Mennell, Kaltenborn, Maitland, McKenzie, Mitchell, Jones and Greenman in the earlier years of manual therapy education. Inspired by these methods of treatment, she became an assistant teacher to Dr. Janet Travell and later an instructor with the Institute of Physical Art (IPA) developed by Gregg Johnson and Vicky Saliba Johnson.

In a few years, she developed her own private practice, at which time she received a large number of head, neck and TMJ pain patients. This became a driver to learn more about cranial osteopathy, craniosacral therapy and how the fields of physical therapy and dentistry could collaborate to help these patients. As she pursued continuing education classes with Dr. John Upledger, he inspired her to learn more about the different systems in the body and how they all integrated for function. During one of her earlier speaking engagements for the Upledger Institute (Beyond the Dura), she met Jean Pierre Barral DO, who inspired the importance of anatomy, the ability to listen to the body and the specificity of tissue dialogue in manual therapy techniques. She has listened and followed his mentoring into understanding the body's deeper fascial relationship of the viscera, vascular, neurological and manual articular systems since 1989. Gail has been an instructor for the Barral Institute since 1991 and became the BI Curriculum Director in 2001.

In her career, she has been invited to speak at multiple professional conferences including National and State levels for the APTA, USC Head, Neck and Facial Pain Clinic, University of California, Irvine (UCI), Beyond the Dura Research Conferences, "Hope" Head Injury Organization, and was the keynote speaker in Italy for the Fascial Manipulation Research Conference presented by Antonio, Carla and Luigi Stecco. She is the Past Director of Physical Therapy for the Integrative Medicine Center at UCI. She is currently part of the Research Team for the Upledger Foundation for their recent studies on Post Concussion Recovery. She currently teaches for the Women's Health Section of the APTA.

Gail earned her Diplomate from the Barral Institute in 2005. She earned her Equine Diplomate in Osteopathy from Vluggen Institute of Equine Osteopathy in 2009 and she earned her Doctorate in Physical Therapy from Rosalind Franklin University, Chicago, in 2013. This doctorate emphasized clinical research so she could contribute evidence based projects to prove/disprove the effects of manual therapy in dysfunctional diagnoses.

At Wetzler Integrative Physical Therapy, you will encounter a whole body approach to your symptoms. Each patient will receive their own specialized care and individualized treatment. We will go deeper than just pain relief to really get to the cause of the problem. 

Our role  is to identify the underlying dysfunction that is perpetuating the presenting symptom. The therapist and patient will work together to develop and implement a personalized treatment program.

Our therapists will function as a team and will often consult with one another on complex cases to ensure the highest level of care. Because of the diverse specialties offered by each therapist, patients may often be scheduled with multiple therapists in the office.

Because of the type of work we do and the limitations and constrictions that are placed upon our therapists, our office is not contracted with any insurance companies. No referrals are necessary.
