Sheilagh Murray


Sheilagh Murray was born and raised in The San Francisco Bay Area, but for the past twenty-five years she and her family have made Phoenix home.  Sheilagh has been involved in dentistry from a young age.  Her first high school job was as a dental assistant.  Her dental assisting career followed her through college at Brigham Young University.   As her children left home she realized how much she missed dentistry, science and learning.  In 2010, she went back to college and earned a degree in Applied Science and completed her licensure as a Registered Dental Hygienist.  Sheilagh finds great fulfillment in the relationships she builds with her wonderful patients.  Sheilagh and Scott enjoy traveling internationally, hiking, photography, studying art and European history.  Their favorite activity is spending as much time as they can with their grown children, and nine beautiful grandchildren.  Life is very busy and incredibly fulfilling!
