Program summary / training goals

The Fellowship at the Weil Foot & Ankle Institute is one of the premier foot & ankle surgical fellowships in the United States.

This fellowship is designed to enhance and refine the skills of residency-trained Podiatric Surgeons.

Under the guidance of fellowship director Jonathan L. Hook, DPM, MHA, FACFAS, and the CEO of Weil Foot & Ankle Institute, Lowell Weil Dr, DPM, MBA, FACFAS, fellows at the Weil Foot & Ankle Institute are exposed to all aspects of foot & ankle surgery. Fellows are exposed to a diverse surgical case volume ranging from forefoot, hindfoot, and ankle reconstruction, total ankle replacement, Charcot foot reconstruction, sports medicine, and trauma. In addition, fellows are heavily involved in clinical decision-making, post-operative management, foot & ankle research, and practice management.

Prior to participation in the Fellowship at the Weil Foot & Ankle Institute, fellows considered for the position will need to have completed a PMSR/RRA comprehensive surgical residency program. The fellowship is designed to refine surgical skills and efficiencies.

Fellows receive tremendous exposure and participate in scientific and business meetings with some of the most influential physicians involved in foot and ankle surgery. In addition, the fellow will be participating in a wide variety of surgical procedures that have been developed by Dr. Lowell Weil Jr.

The fellowship is committed to research, and the fellows are integral research team members. Fellows participate in all aspects of research from hypothesis and designing research studies, to participation in FDA clinical trials, to overseeing students in their research activities. Fellows are required to create studies that are submitted for peer-reviewed publication, and they are encouraged to present their research in lecture settings.

Additionally, fellows have their own dedicated clinic in which they will have the opportunity to hone their clinical skills, patient communication skills, medical/business skills, and the art of surgical consultation and management of post-operative patients and the associated complications.

The Fellowship at the Weil Foot & Ankle Institute is the longest-running in Podiatric Surgery. Since 1995, Graduate Fellows from the Weil Foot & Ankle Institute have moved on to provide significant leadership and influence on a local and national basis.

Dr. Christopher Collazo

Since I was little I have always known that medicine was a career path that highly interested me. As I got older and started to learn more about medicine I became focused on going into medicine. Through high school and college because of baseball, I was exposed to various aspects of medicine but Podiatry always stuck out to me because of all the opportunities that it allowed the physician including being a surgeon. Following graduating from Texas A&M International University with a BS in Biology, I decided to focus on the care of the foot and ankle and I enrolled in Des Moines University. Upon graduating with my DPM in 2016, I began my residency at Sanford Health in Fargo, ND. In June 2019, I graduated from my residency and have now started my Fellowship with the Weil Foot, Ankle & Orthopedic Institute. I am beyond excited to be in Chicagoland and to be a part of the Weil Foot and Ankle team.
