"One of my favorite things about working at Hebron and Colchester Eye Care is how we take a really personal approach to eye care.  We are treating the patient as a whole person rather than just a set of eyes. The pace that we keep in our office allows me to address the whole range of concerns that a patient has, rather than just one specific thing at a time. I also love how this office really functions like a whole family rather than a workplace. Everyone comes to work happy to be here, and you can really tell."

When not working, Dr. Ola enjoys skiing, snowshoeing, canoeing/kayaking, learning to surf, traveling, reading novels, and quilting.
