Sean Greer is our Certified Licensed Orthotist, who specializes in pediatric orthotics and cranial molding.  Sean is originally from Parkersburg, WV and has practiced over the past 16 years in Brooksville, Fl, Morgantown, WV, Hickory, NC and Pittsburgh, PA. Sean is a 1999 graduate from West Virginia University in Morgantown, WV and completed his Orthotic education at Newington, CT. He is certified through the American Board of Certification (ABC) in Orthotics, and is state licensed. Miller Prosthetics & Orthotics is a progressive clinic that provides a state-of-the-art modern approach and the latest technologies to our patients. Sean’s experience and knowledge further increases the services we provide to the region. Here is a personal note from Sean:   My name is Sean Greer and I am a Certified and Licensed Orthotist specializing in pediatric care. I was born and raised in the Mid-Ohio Valley, but like so many others, I left the area in search of my education and adventures. Upon completion of my orthotic education, I was fortunate enough to work with some of the best Orthotics and Prosthetics companies in their markets. I was able to specialize in pediatrics while working with some of the doctor’s at many highly rated universities and children’s hospitals. I have worked with Physiatrists, Orthopedists, Neurologists, Neurosurgeons, Craniofacial specialists, and Physical and Occupational Therapists from West Virginia University, Wake Forest University, Levine Children’s Hospital in Charlotte, and UPMC Children’s Hospital in Pittsburgh. All during that time, I hoped that I would one day be able to bring my expertise to the families around my home area. Thankfully, I have been able to do just that. I have found that many general orthotics clinics treat children as if they are the same as “adults in miniature.” It takes an orthotist who has specialized in the treatment of children to  understand that this is not the case. Children require specialized consideration for treatment due to the changes of growth and development, as well as a long term outlook on their prognosis. I am proficient in all types of bracing including custom and pre-fabricated designs from head to toe. I also have been fortunate enough to be able to further specialize in devices for re-molding the body, including cranial remolding helmets, scoliosis bracing, and Blount’s KAFOs. I was among the earliest clinicians certified through FDA required training to provide the Starband Helmet by Orthomerica in 2003. I have lectured to Physical Therapy schools and Orthotics and Prosthetics programs, in addition to being a speaker at the Orthomerica Star Summit meeting for cranial remolding specialists. I have been building my experience over the last 15 years and I am eager to offer my services to providers, therapists and families in the area.

Natalie Thomas is our Certified Licensed Prosthetist Orthotist who moved to the area in 2021.  For as long as she can remember, Natalie had always been interested in the medical field and learning how the human body works. A former athlete and avid marathon runner, Natalie pursued her undergraduate degree in exercise physiology at The Ohio State University and looked for a way to continue challenge herself to apply her knowledge and experience of human kinematics in a way that would allow her to help others realize their full potential in life. Combining the unique aspects of hands-on creativity, patient care and human connection, and biomechanics made the field of orthotics and prosthetics a perfect fit. She proceeded to receive her Master’s Degree in Orthotics and Prosthetics from Eastern Michigan University in 2016. Natalie is a CPO (certified prosthetist/orthotist) certified by the American Board for Certification in Orthotics and Prosthetics and is licensed in the state of Ohio and she has had the opportunity to work in several O&P offices throughout her residencies and early career giving her a breadth of experience and exposure that is rare for such a young clinician. Natalie is passionate about remaining an eager, lifelong student of the profession and is thrilled to bring her energy to Miller Prosthetics & Orthotics. She can’t wait to continue to grow and learn from her new team and local healthcare community and looks forward to making lasting connections with patients and colleagues here in the Mid-Ohio Valley.
