Gait analysis at Walter Reed National Military Medical Center

While in clinic, she had the rare opportunity to intern with Dr. William Morgan at Walter Reed National Military Medical Center in Bethesda, MD.  During her training, Dr. DeVries practiced hospital-based chiropractic, which enabled her to work closely with the nation’s leading medical specialists to provide the most comprehensive and effective care possible for her patients.  Furthermore, she received extensive training in reading MRIs of the lumbar spine, which serves her well when treating patients with spinal stenosis and disc herniations, disc bulges, and disc degeneration.  She was honored to have cared for the courageous men and women who actively serve our military, as well as the wounded warriors who were both physically and mentally injured during their service.  It is because of this opportunity that Dr. DeVries specializes in hospital-based chiropractic and care for multiple-limb amputees.


While at Walter Reed, Dr. DeVries had the privilege of rotating through various departments alongside medical students and learning from the best physicians, specialists, and surgeons in the nation.  Some of her rotations included: wounded warrior physical and occupational therapy, pelvic floor physical therapy, gastroenterology, prosthetics, orofacial pain, rheumatology, diabetes clinic, neurosurgery, orthopaedic surgery, orthopaedic casting (here she learned how to cast!) EKG training, gait analysis at the gait lab, and inpatient chiropractic and physical therapy.

Upon meeting the requirements for her clinical training, Dr. Cassie was invited to participate in an extended rotation in the Physical Medicine and Rehabilitation department at Walter Reed, where she learned basic EMG skills, dry needling, acupuncture, traumatic brain injury patient care, active isolated stretching protocols, and witnessed various non-chiropractic pain management techniques.  During this rotation, she was also taught Neuro Kinetic Therapy (NKT) by David Weinstock, alongside the doctors of the Physical Medicine and Rehabilitation.


While working under the supervision of Dr. Morgan in Maryland, Dr. DeVries also had the chance to work among the sports medicine and orthopaedic teams of the United Stated Naval Academy in Annapolis, MD.  She primarily treated the Navy football team, but would occasionally see other athletes as well.  Here, she practiced chiropractic as a means for injury prevention and athletic performance enhancement.

in Gainesville, VA.

Following her internship at Walter Reed, Dr. DeVries trained at a sports chiropractic and physical therapy office in Gainesville, VA.  While there, she treated elite athletes and olympic competitors and further refined her clinical skills. She had the opportunity to learn kinesiology taping (KT Tape, Rock Tape) and physical therapy for scoliosis, and then was invited to guest lecture at George Mason University on how to perform kinesiology taping.


She also participated in an injury prevention program for an elite swim team and developed hydration protocols to keep the team functioning optimally.

Now Dr. Cassie DeVries DC is back in Frederick (wahoo!), practicing at Ballenger Creek Chiropractic (604 Solarex Ct #101, Frederick, MD 21703) alongside Dr. Brandon Steinbar. Dr. Steinbar is the chiropractor that helped Dr. Cassie after a serious weight lifting injury and is the reason Dr. Cassie pursued a career in chiropractic.
