Dr. John Zalesky holds a DMD from Nova Southeastern University College of Dental Medicine and a Master's in Biomedical Science from the University of Medicine and Dentistry of New Jersey. He completed his General Practice Residency at Denver Health Medical Center, then pursued advanced training as Chief Resident at the University of Colorado School of Dental Medicine General Practice Residency, focusing on implants and complex prosthodontic cases.

Today, Dr. Zalesky divides his time between private clinical practice and a faculty position at the CU School of Dental Medicine. His clinical work spans advanced surgery, dental implants, the Pinhole Surgical Technique, All-on-4®, full-mouth rehabilitation, and orthodontics. It's an uncommon breadth — and it's the reason his teaching lands. Everything he presents to an audience, he's actively doing in a chair.
As a speaker for Catapult Education's Speakers Bureau, Dr. Zalesky has delivered CE across the country on laser dentistry, full-arch implants, restorative workflows, and the digital technologies reshaping general practice. He serves as Key Opinion Leader for both DEKA Dental Lasers and Carestream Dental, partnering with each on clinical content and practitioner education.
His leadership extends beyond teaching. He is the Immediate Past President of the Colorado Constituent of the Academy of General Dentistry, and currently serves as Executive Director and Treasurer of AGD Region 14 — representing seven states: Arizona, Colorado, Hawaii, Nevada, New Mexico, Utah, and Wyoming.
