“The work of the Osteopath is to adjust the body from the abnormal to the normal; then the abnormal condition gives place to the normal and health is the result of the normal condition.”

Our Officers

The mission of this organization is to promote the benefits and
advance the practice of equine osteopathy.
Ann-Marie Hancock, DVM, EDO

Ann-Marie Hancock was raised in the San Francisco Bay Area of Northern California, where she was active in Pony Club and competed in lower level three day eventing horse trials.

Ann-Marie completed her studies at Colorado State University in Fort Collins, Colorado,  graduating with a BS in Equine Science, an MS in Anatomy and Neurobiology and a DVM in 2003.

Following veterinary school, she moved to Greenville, North Carolina and practiced at a general equine practice for ten years.  She developed an interest in integrative therapies during that time, finishing the IVAS Acupuncture course in 2007 and then taking the Equine Osteopathy Course at the Vluggen Institute in San Marcos, Texas.  She finished her certification and is registered as an Equine Osteopath, EDO.


Ann-Marie owns the True North Equine Veterinary Services in Marshall, Virginia in the heart of horse country.  Her goal is to use integrative veterinary medicine (and osteopathy) to treat the whole horse and rider combination, by looking at as many different ways to influence the movement and performance of the horse as possible.

Vice President
Lorre Mueller, Equine Osteopath EDO®

 Lorre Mueller grew up on Martha’s Vineyard in Massachusetts and was the typical horse crazy girl. She began riding at 5 and continued until she went off to college at Boston University.  


Lorre Mueller moved to Texas in 2006, and as a part of that move, she knew she wanted to have a career that involved horses. One of her horses, Ditti, had quite a few physical problems and she inspired Lorre's journey helping horses.  


From Lorre:

"My journey started with a course and certification in myofascial release, and then on to certification in deep tissue massage and equine sports massage.  In 2010, I went on to become a certified practitioner in the Masterson Method®.   The Masterson Method® helped give me the understanding that the horse actually had a role in this healing process; that I had to work “with” the horse not “on” the horse.  I have continued on with the Masterson organization as a practitioner, an instructor, mentor, and coach.  Again wanting more education, I was guided to equine osteopathy, which has now become my deep-felt passion as well as my career.  I graduated from the Vluggen InstituteSeptember 2014.  



I work full time as an Equine Osteopath EDO® throughout the greater Austin, TX area.  I attend continuing education at the Vluggen Institute and I have trained in equine dentistry, nutrition, laminitis, and advanced craniosacral therapy. 

Frances Loehr

Frances Loehr grew up in Duluth, Minnesota, actively participating in the MN 4-H horse project in all show classes, training, western heritage, quiz bowl, hippology, and horse judging.  In 2003, she won the Dan Patch Award, which recognizes achievement, leadership, and service in the horse project.


She pursued a B.S. in Science in Agriculture and French at the University of Minnesota, and an M.S. at the University of Wyoming in Ruminant Nutrition.  She was introduced to Equine Osteopathy through Randy Lindsey in early 2011, and began taking courses at the Vluggen Institute in San Marcos, TX, that April.  Frances graduated from the Vluggen Institute in September, 2014, and is an Equine Osteopath, EDO.

Frances and her husband, Chris, own Loehr Horse Care, LLC, and serve the Black Hills region of South Dakota and Wyoming.  They offer osteopathy and barefoot trimming care, improving mobility and performance for horses in the region.  She lives in Hermosa, SD, with her family.

Kerilyn Peck

Kerilyn Peck grew up in Sandy Hook, Connecticut and was an active rider throughout her youth and teenage years, competing in Hunter, Equitation and Jumper divisions at local and “A” Rated shows throughout the Northeast. She was also an active, open rider, and Captain for her Alma mater’s equestrian team, Fairfield University Equestrian Team.


She pursued an undergraduate degree, a Bachelor of Science in Economics and Mathematics, and is currently pursuing a Masters of Science in Applied Economics through Johns Hopkins University. After suffering from residual injuries from a car accident in 2010, she set out to find an alternative therapy that had lasting results. Kerilyn was lucky enough to find an Osteopath in CT and never looked back. The profound impact that osteopathy had on her life initiated a passion and a curiosity. Could osteopathy have the same impact on her hard working horses? At one point, she thought the only option would be starting her own program. Much to her surprise, her osteopathic therapist discovered and introduced her to The Vluggen Institute.

Kerilyn started attending the Vluggen Institute in San Marcos, TX in October of 2013 and is set to graduate in November of 2017.
