Marshall Collier
Certified Massage Therapist
Certified Personal Trainer
Certified Active Release Technique (A.R.T.) Practitioner
“Growing up with asthma made it extremely difficult to breathe and usually left me feeling sore in my upper thoracic chest. Receiving massage therapy as well as chiropractic care helped to relieve my symptoms as well as bestow knowledge to help build strength and stability in those areas.”
Education and Professional Development
Marshall’s positive experience with massage led him to attend the Cortiva Institute for massage therapy, graduating in 2005. He is a Licensed Massage Therapist in Illinois and is full body certified in Active Release Technique® (ART®).

Collaborating With Other Healthcare Professionals
For Marshall, the most fulfilling part of his job as a massage therapist is being able to help people. As part of an office of integrated health care, he also enjoys working with other healthcare professionals collectively and conveniently to help relieve patients’ pain or discomfort.
Staying Active in Peoria
When he’s not at the practice, Marshall enjoys spending time with his wife and two daughters. They like hiking on trails, visiting with family and taking trips to see his in-laws in the U.S. Virgin Islands.
Karl Houck
Certified Massage Therapist
Certified Personal Trainer
Certified Active Isolated Stretch (A.I.S) Practitioner
After overcoming his own health crisis years ago, Karl became fascinated with health and decided to enter massage school, where he fell in love with the healing potential of the human body. Karl is Board Certified in Massage Therapy, graduating in 2001 from the Onondaga School of Therapeutic Massage 1,000-hour program.
In order to provide the best possible service for his patients, he continues to take professional development courses. Recently, he’s participated in courses including functional movement systems, Russian Hardstyle Kettlebell and Barefoot Training for foot health.
As Karl puts it, the best part about his job is being able to collaborate with patients to find solutions that are tailored to their unique needs, ultimately improving their overall health and wellbeing.
Outside of the practice, Karl enjoys playing racquetball and spending time with his family. Karl is also a trained opera singer-don’t be surprised if a little song makes it into your time together!
