Meet Our Doctors

Dr. Erin Gray

General Dentist

Dr. Erin Gray was born in Edmonton and grew up in Calgary. She received her Bachelor of Science degree in Honors Chemistry from the University of Western Ontario, while playing on the varsity hockey team. She went to the University of British Columbia for dental school. After graduating in 2010 with her Doctor of Dental Medicine, Dr. Gray moved back to Calgary to be near her family and start her career. 

Dentistry is a constantly evolving industry and Dr. Gray feels very strongly about staying current in the various treatment options that she can offer her patients. She loves attending dental lectures and is a member of several dental study clubs in Calgary. She has attended many courses over the years on comprehensive treatment planning, dental materials, root canal therapy, Invisalign (clear aligner orthodontics), neuromodulator therapy (Botox/Xeomin), sleep dentistry and sleep apnea.
Dr. Gray truly enjoys working with children and does a lot of pediatric dentistry. She has very positive memories of the dentist from when she was a child, and she strives to give each of her small patients an outstanding dental experience like she had.

Erin has volunteered with an organization called Kindess in Action and travelled to Peru to provide dental care to patients in an underprivileged country. The Peru trip was an eye-opening and amazing experience and she hopes to volunteer with KIA again one day.

Away from the office, Dr. Gray and her husband Greg are busy with their three daughters. Dr. Gray just recently had twins and her house is now run by toddlers. If she has some free time (which is a big “if” with twins), Dr. Gray loves DIY projects, playing baseball, skiing, working out, and travelling.

Dr. Anne Kelly

General Dentist

Dr. Anne Kelly grew up in Calgary and Victoria, BC. She completed her Bachelor of Science (2005) and Doctor of Dental Medicine (2010) degrees at the University of British Columbia. Following graduation from dental school, she completed a General Practice Residency at Montefiore Medical Centre in the Bronx, New York. 

As a child, Dr. Kelly had a lot of cavities in her baby teeth and spent many hours in the dental chair! She had a wonderful dentist who always made the experience positive. She feels very fortunate to have had these experiences as a child and even more fortunate that it led her to a career in dentistry that she loves. Her goal is to make every visit a positive one for her patients.

Anne is committed to providing her patients with high quality dentistry in a warm and welcoming environment. She enjoys getting to know her patients and improving their function and esthetics. She enjoys all aspects of dentistry including fillings, crown and bridge, extractions, root canals and esthetic dentistry.

After practicing in BC and Ontario, she is thrilled to be back living in Calgary. Outside of work she enjoys playing tennis and spending time with her husband and three boys
