I have had the pleasure of working for Dr. Woolner since 2002 as his receptionist.

I have 2 adult children and grandsons whom I spend all my time off with. In the summer we spend our weekends in the country at our farm.


My name is Nancy. I was fortunate to start working at Northwest Dermatology in early 2017. I was a stay at home mom for 10 years and have loved the transition back to work with such a great team!

I have two awesome children and a very supportive husband. When I am not at work I am usually at the hockey rink in the winter or camping in the summer.

Hello, my name is Susan. I grew up in Edmonton and moved to Calgary in 2006. I first started working in pediatric homecare after graduating from an LPN program in 2004. Since that time I have worked in different areas of dermatology both medical and cosmetic.

I enjoy my family of pets and humans and we like to pursue outdoor activities weather permitting.

Hi, my name is Tami. I have worked in the field of dermatology since 1988. I have learned many things over the years about dermatology and people in general. For the last ten years I have worked with Dr. Woolner as a laser technician. I enjoy our close team atmosphere and we have a lot of fun while helping many people. The field of dermatology is always changing with new technology and new ideas and it is very exciting to be in the forefront.

My husband, son and I love to go camping. We enjoy dirtbiking in the summer and snowmobiling in the winter (when it’s not too cold).


Hello, my name is Wendy and I am the Clinical Research Coordinator at Northwest Dermatology and Laser Centre. I have been involved in coordinating clinical trials for 19 years, the last 6 in the area of dermatology. I enjoy the flexibility that clinical research allows and it is always exciting to participate in the process of developing new and effective treatments for various dermatologic  conditions, some of which can be very debilitating.

Time away from the clinic is spent with family and friends attending various activities around the city or relaxing at our cabin on the lake.



Hi, my name is Lois and I had the pleasure of setting up the clinic for Dr. Woolner.  I am the jack of all trades, master of none so they gave me the dubious title of clinic manager.  Outside the office I enjoy volunteer work at our community association, golfing and running with my girlfriends in Fish Creek park.
