Dr. Eric Mack , DDS

Dr. Mack was born and raised in southeast Arizona. He attended Eastern Arizona College and then moved to Texas to continue college at UT Dallas and then he went on to graduate from the University of Texas, Houston Dental Branch. 
Following dental school, he joined the US Public Health Service in Fairbanks, AK where he lived and worked with Native Americans for two years.  He then moved to Colorado and practiced general dentistry for several years in Highlands Ranch, CO.  His developing love of oral surgery led him to go back to school and complete a post-graduate program in Oral Surgery at the University of Nebraska Medical Center College of Dentistry in 2012.

Dr. Mack has a unique background in dentistry, having worked in orthodontic offices prior to dental school, becoming a Certified Dental Technician, working in Public Health in rural Alaska on Native Americans, owning a general dentistry practice, going back to school, and now exclusively practicing Oral Surgery.  His well-rounded background give him a unique perspective on oral health.  For 5 years, Dr. Mack worked in north Texas with his wife’s family and just returned to Denver this past summer after an opportunity to come back to Colorado presented itself.  He absolutely loves working with patients from all over the Denver area and loves being back in Colorado.

 Dr. Mack has been happily married for 20 years to his beautiful wife, Tosha, and is the proud father of six children, three boys, and three girls. He is in the Texas Air National Guard and loves to spend his free time with his family working and playing together. He just finished restoring a 1957 Chevy pickup that he’s planned and dreamed about since his early teen years. He loves sports and the outdoors and is especially passionate about college football.
