Meet Dr. Mark A Paciorek
I grew up in the Syracuse area, and nothing gives me more pleasure than being able to provide my hometown community with excellent orthodontic care. The people I treat aren’t just patients; they are also my family, friends, and neighbors. I strive to give each patient I see friendly, personalized attention and develop meaningful relationships with them during and after their treatment.
I received my bachelor of science degree in Pharmacy from Albany College of Pharmacy and I worked as a pharmacist prior to and during my dental training. I attended the University of Buffalo Dental School for my dental degree and specialty training at the master’s level, where I graduated top in my class. I continue to remain a leader in the field of orthodontics. In my pursuit of continued excellence, I attend numerous continuing education programs throughout the year to maintain the highest quality of care for my patients. I am also a frequent lecturer, sharing my orthodontic expertise at dental society meetings and dental study clubs.
