Dr. Tepper started practicing podiatry with Dr. David S. Jacobson in East Los Angeles in 1977. Later, he opened his first office in Ontario in 1981. His approach is to start with the most conservative care before considering aggressive options if necessary, indicated, or desired.

Dr. Tepper decided to become a podiatrist after suffering from his own foot problems. He was experiencing pain in the arches of his feet when he started running long distance at Lawrence High School in Cedarhurst, New York where he was captain of the cross country team. Dr. Tepper continued running for the C.W. Post College track team in Brookville, New York where his foot problem became worse and he was diagnosed with plantar fasciitis. This influenced his decision to attend California School of Podiatric Medicine that was known throughout the country for their expertise in podiatric biomechanics and foot and ankle surgery. Dr. Tepper’s interest in biomechanics became a deeply seeded thirst for knowledge in structure and function; the thread that ties all foot and ankle care together.

He started wearing rigid, functional orthotics and was able to remain active in competitive sports such as tennis and basketball.

With medicine and technology evolving; Dr. Tepper continues in depth training and education. He does over 100 hours in continued medical training on wound care, foot and ankle surgery, sports medicine orthopedics and trauma yearly.

Dr. Tepper has been a member of the California Podiatric Medical Association for the past 38 years and the past 15 of which he has been an officer in the Inland Society, including president of the local society and 5 years on the board of the state association, including a year as treasurer of that organization.

Dr. Tepper has been a member of the staff at San Antonio Regional Medical Center and Ambulatory Center for the past 25 years.

Dr. Marchis-Crisan decided to become a podiatrist after visiting the United States for an externship. She was hosted by a knowledgeable and skillful podiatrist named James Clough, at his private practice in Great Falls, MT. While there, she became intrigued by the complexity of the foot and ankle and how it could help improve pain and alleviate symptoms both through conservative and surgical care. Even though she was a family doctor who passed the boards as a foreign medical doctor graduate and became certified as a physician in the United States.

Dr. Adam Marshall Shapiro’s appetite and thirst to become a Podiatrist came from observing his grandfather’s painfully debilitating experience. His grandfather made poor health choices which was fueled by diabetes and had robbed him of his golden years. His inability to walk and quality of life was progressively taken away as a result of amputations. It is at that point, Dr. Shapiro decided to become a Podiatrist to make sure this did not happen to anyone else.

Dr. Shapiro graduated from The University of Colorado at Boulder with a Bachelor of Arts Degree in History. During that time, he had a once in a lifetime opportunity to study abroad with the noted Nobel Peace Prize recipient, Archbishop Desmond Tutu. His belief of eliminating and addressing a person’s suffering was paramount. While visiting communities within South Africa, Brazil, Viet Nam, China, India, Malaysia and Japan, he was provided insights into how one’s lifestyle impacts access to health care for health maintenance, diagnosis, treatment and prevention. During his undergraduate years, Dr. Shapiro also served the community while working in the hospital environment and also as an Emergency Medical Technician (EMT). While working in a hospital setting as well as an EMT, he was able to work with young and old trauma victims, neurologically unstable patients and the critically ill.

Dr. Adam Shapiro received his DPM from world class: The California School of Podiatric Medicine at Samuel Merritt University. While in medical school, Dr. Shapiro volunteered in a Podiatrist’s office and was a Prosector. Dr. Shapiro received multiple scholarships for his outstanding academic performance.

Dr. Shapiro completed his competitive 3 Year Podiatric Residency in Chicago, Illinois at Weiss Memorial Hospital along with its satellite associated off-site facilities. During this time, he worked alongside a large group of talented Podiatric Physicians in their private offices and received extensive training in the repair of acute fractures of the forefoot, midfoot, and rearfoot, external fixation, as well as bunion corrections, hammertoe deformity repairs, limb salvage, and plastic surgery.

There is no better way to help others than being a Podiatrist where one gets a chance to make a difference every day. Dr. Shapiro’s Medical School education and Residency training along with the diabetic challenges of Dr. Shapiro’s grandfather, his performance as an EMT, his hospital employment, his volunteering in a Podiatric setting, and his world travels have taken Dr. Shapiro through many cultures to gain a better understanding about Podiatric disease processes, the wins of disease prevention, treatment, and its impact on one’s physical, mental and social well-being. All these experiences, with the commitment to continuous learning about medicine, energize Dr. Shapiro’s enthusiasm to give back to people and plan for future challenges in the world of Podiatric Medicine.

Born and raised in Southern California, Dr. Shapiro’s sports activities include long distance running, snowboarding, basketball and rock climbing. He also enjoys watching the University of Colorado Buffs Basketball and Football teams.
