Meet Our Dentists


Dr. Stephanie Brown D.D.S., B.Sc.

I graduated from the University of Alberta with a Bachelor of Science, followed by a Doctor Dental Surgery degree. My husband and I moved to Athabasca in 2017 and our family has since grown to include two children that we are so excited to raise in this beautiful small town. When I first joined the Athabasca Dental team, I was immediately impressed by the caring staff and I knew it was the kind of environment I’d be proud to work in. Now, I can confidently say that my first impressions were right and I feel lucky to provide the best quality of care with an exceptional team.

I am passionate about providing quality dentistry to all of my patients. I do my best to explain all treatment options so that my patients can both understand their dental work, and make educated decisions. I always take time to make sure my patients are comfortable and pain free throughout their appointment. I love working with children and adults alike. I welcome patients of all ages. I do not take shortcuts and feel strongly about providing quality dentistry.

I enjoy exercising, being outdoors, and spending quality time with my family. My husband and I have taken on multiple volunteer and fundraising initiatives. In 2018, we traveled to a remote community in Nicaragua to provide dental care for children in severe need of medical/dental attention. Giving back is a very big part of our lives and we do our best to take on a project every year that will in a positive way.

I look forward to continuing to be a part of the Athabasca community and can’t wait for my children to grow up here!


Dr. Peter Karczmarczyk D.D.S., B.Sc.

After graduating from the University of Alberta in 1998 I came to Athabasca to work as a new graduate, after a short time the opportunity came to purchase the clinic.

I live here in Athabasca with my wife and two daughters, and enjoy golfing, travel and spending time at the lake.

I also have a firm belief that every patient gets treated as if they were my family. My number one priority is making sure my patients are comfortable and they received a valuable service.


Dr. Aran McCullagh D.D.S., B.Sc.

Graduated from the University of Alberta in 1997 and started at the Athabasca Dental Clinic in September 2010. As a dentist, there are many aspects to my job. I feel the most important is to listen to the concerns of the patient and provide them with all the possible treatment options. I have taken additional training in orthodontics, root canals and one-visit crown to be able to provide as much treatment as I can here in town. As well, I try to make patient appointments as comfortable as we can by providing gentle freezing and compassionate care.

We moved to Rochester in 2010 with our three children. We were looking for rural lifestyle and all the advantages it has to offer. We really value our family time together especially on the ski hill. I enjoy playing guitar, reading and spending time outdoors when I’m away from the office I volunteer at the Rochester School as part of their Band program.

The satisfaction that comes with my job is when I help someone. What I do can make a big difference in someone’s life. Sometimes that means getting them out of discomfort with a toothache. Sometimes that means improving their smile and how they feel about themselves. And sometimes that means getting them through a nervous experience by giving lots of TLC. Every day presents new challenges, and dealing with people means that the unexpected always can happen.


Dr. Derek Dribnenki

I was born and raised in the neighboring community of Lac La Biche. I completed my Bachelor of science degree at MacEwan University and moved to Ireland to study Dentistry at the University of Cork. I was fortunate to study with students from several countries including many fellow Canadians. I returned home and began practicing in the communities of Athabasca and St. Paul.

In my spare time, I enjoy fishing, golfing, cooking, camping and traveling. My studies in Ireland not only provided me with a great education but the opportunity to travel and see many European countries. I plan to continue to further my travel pursuits, expanding my appreciation of cultures all over the globe.

As a dentist, I believe that patient care, comfort and service are a critical part of my practice. I enjoy conversing with my patients from all different backgrounds. I appreciate the warm welcome from all the staff and community and I look forward to continuing to serve patients at Athabasca Dental.
