The Antosz Vincelli Orthodontic Team
in Calgary & Canmore, Alberta


Dr. Mark Antosz, DMD D. ORTHO



Dr. Antosz was born and raised in Victoria, BC and spent time in Dawson Creek and Prince George, BC, before attending the University of British Columbia.


He graduated from the University of British Columbia with his degree in Dental Medicine in 1980 and entered private general practice in Dawson Creek until 1985. Dr. Antosz, his wife Brenda and their first son moved East, and he began a combined program of Specialization in Orthodontics and Dentofacial Orthopedics with a focus on bone cell physiology at the University of Toronto.



In 1988, they moved back to the West to Calgary (with 2 more sons in tow) where he began his private orthodontic practice. They have been proud to call Calgary home ever since.


Dr. Antosz still enjoys the worlds of Marvel and DC Comics and science fiction, and that crazy collection of statues, lightsabers and paintings are there because… well, he thinks itʼs cool!


Dr. Robert Vincell, DMD, FRCD(C)



Born and raised in Montreal, Quebec, Dr. Vincelli attended McGill University for both his Bachelor of Science (Major in Physiology) and Dentistry degrees. He graduated in Dentistry in 2015 and then headed south to Philadelphia for his certificate in Orthodontics and Dentofacial Orthopedics at the University of Pennsylvania.



With always a love for nature and the outdoors (he is an avid skier, hiker and cyclist), Dr. Vincelli wanted a change from the hustle and bustle of the East. So, he headed West. Calgary’s unique offer of both metropolitan and outdoor lifestyles is what appeals to him most.


Besides roaming around in the wilderness, you may also find Dr. Vincelli locked up in a music recording studio or playing at a music venue. Having played guitar and mandolin in a Montreal-based folk-rock band, Dr. Vincelli continues to incorporate his love for music into his life.


Dr. Ziana Esmail, DDS MSc,



Dr. Esmail completed her Bachelor of Science at McGill University and received her Doctor of Dental Surgery with distinction from the University of Western Ontario. She was awarded the Ontario Dental Association Proficiency award for demonstrating merit in dentistry and making meaningful contributions.


Dr. Esmail furthered her education by completing a General Practice Residency at Mount Sinai Hospital. While there, she received clinical training in hospital dentistry, treating medically compromised and special needs patients. She then moved to central Canada to complete her Masters of Science in Orthodontics and Dentofacial Orthopedics at the University of Manitoba.



Dr. Esmail was born and raised in Calgary, Alberta. In her personal time, Dr. Esmail enjoys practising yoga, immersing herself in nature with hiking and camping, and exploring new countries. After moving around Canada, she is excited to return to her roots and provide quality orthodontic care in her home city.
