Dr. Casillas is a San Antonio native and a graduate of Central Catholic
High School, St. Mary’s University and the School of Medicine at
University of Texas Health Science Center at San Antonio. He completed
his orthopaedic surgery residency in Memphis, Tennessee at the prestigious
Campbell Clinic. His post-graduate training included a geographically
and anatomically varied experience, starting with an AO fellowship under
the guidance of Professor Doctor Reinhold Ganz at the Inselspital in Bern,
Switzerland. This fellowship focused on conservative hip surgery but included
an extensive exposure to the center’s expertise in trauma surgery
and internal fixation.
This was followed by the opportunity to participate in the United Kingdom’s
National Health Service as an honorary consultant, which involved visiting
and lecturing on rotational arthroplasty of the hip at several hospitals
across England. A fellowship at Italy’s Ospedale Generale Provinciale
in Lecco completed his European experience. Directed by Chief of the Ilizarov
Center, Dr. Maurizio Catagni, this fellowship focused on external fixation
with the Ilizarov device and enabled Dr. Casillas to visit hospitals in
Milan, Rome and Bologna.
His first focused foot and ankle experience took place in Cape Town, South
Africa under the guidance of Dr. Tony Mullins, the regional foot and ankle
specialist. Dr. Casillas concluded his eighteen-month fellowship in California
with a six-month fellowship directed by Dr. Roger Mann, the most recognized
orthopaedic foot and ankle authority worldwide.
Dr. Casillas has lectured across the United States and has published a
collection of book chapters and journal articles. Most notable are the
chapter written in DeLee and Drez’s Orthopaedic Sports Medicine,
and the chapters co-written with Dr. Mann in Garrett’s Principles
and Practice of Orthopaedic Sports Medicine, and Chapman’s Orthopaedic Surgery.
Six years after starting private practice, Dr. Casillas served on a team
focused on developing and gaining FDA approval of the Salto Talaris ankle
replacement. Professionally, he continues to work with innovative companies
with products or devices that help people.
He enjoys promoting children’s charities of San Antonio as a member
of the Texas Cavaliers and as a board member of the Texas Cavaliers Charitable
Foundation. Dr. Casillas volunteers his time as team physician for the
Saint Mary’s Hall Varsity football team, and for other high schools
in Bexar County.
