Dr. David Robert Walker PhD

First and foremost, Dr. Walker is a lover of Jesus Christ. He received his PhD in mechanical engineering from the University of Florida. Dr . Walker is the CEO and founder of Rehoboth Innovations. After spending 11 years working on improving the mobility ofpatients through the development and use of methodologies to quantify motion and force of the shoulder he has now branched out to improve both implant design and surgical technique. Collaborating with the Gary J Miller Orthopaedic biomechanics laboratory, National Center for Simulations of Rehabilitation Research (NCSRR) and Computational biomechanics laboratory Dr. Walker has developed a framework to predict muscle performance based on surgical and mechanical factors. Dr. Walker served as a principal investigator on a grant from the American Shoulder and Elbow Society where we quanitifed the kinematics and kinetics of the reverse shoulder arthroplasty during functional activities (Abduction, scaption, flexion and Internal\external rotation). These studies have been presented at the Orthopaedic Research Society, International society of Technology in Arthroplasty, the American Association of Orthopaedic Surgeons and are have currently been published in the Journal of Shoulder and Elbow Surgery (JSES). Dr. David Walker has and currently serves as a consultant to several orthopedic manufacturers.

Prior to joining Rehoboth Innovations LLC, Dan was Entrepreneur in Residence at the Florida Institute for the Commercialization of Public Research where he helped turn Florida-based research into start-up companies. He served as the CTO at IMDS (acquired by CoorsTek Medical), where he played an instrumental role in driving the formation and expansion of the Co-Innovation^TM team, developing and launching over 100 new medical device products worldwide for over 12 years.

Dan co-founded JustWin Medical whose arthroscopic knee technology was acquired by Innovasive Devices, then J&J DePuy Mitek, where he was an Engineering Manager. He also co-founded Orthodyne, whose internal bone lengthening technology was acquired by Orthofix. He is a registered U.S. Patent Agent and inventor on over 120 granted U.S. patents in the areas of additive manufacturing, advanced materials, orthopedics, arthroscopy, spine, neurology, surgical instrumentation, and other medical procedures. He holds a B.S.E. and M.S. in Mechanical Engineering from the University of Central Florida.

Dr. Mark Frankle MD

Dr. Mark A. Frankle has been with Florida Orthopaedic Institute since 1991. He attended Rush University College of Medicine after completing three years of undergraduate studies at Grinnell College in Iowa. Dr. Frankle completed his residency training at the University of South Florida. After residency, he completed an orthopedic pathology and orthopedic implants fellowship at Rush-Presbyterian St. Lukes Hospital. He then completed a reconstructive technique research fellowship program at the prestigious AO/ASIF Prosthetic/Implant Research and Development Complex in Davos, Switzerland. Dr. Frankle then completed an adult reconstructive surgical fellowship at the Mayo Clinic in Rochester, Minnesota.
Dr. Frankle serves as the Director of the Biomechanical Shoulder and Elbow Research Lab at the University of South Florida College of Engineering and is the Director of the annual course, “Current Concepts in Shoulder and Elbow Surgery.” He has published numerous articles in professional journals and maintains ongoing research projects, presenting his work annually at various professional conferences. Dr. Frankle has designed implants and instrumentation used in shoulder replacement for several different orthopedic companies. Dr. Frankle received the prestigious Charles S. Neer Award for Basic Science from the American Academy of Orthopaedic Surgeons.
