A little about us.

Dr. Marguerite Duncan, BSc, DDS, MSc, FRCD(C)

 Dr. Marguerite Duncan

My name is Dr. Marguerite Duncan.  I love smiles.  I believe in the impact that the ability to smile with warmth and confidence can have on one's overall well-being. As an Orthodontist (dental specialist), I have dedicated my career to transforming smiles, encouraging self-confidence, and enhancing oral health. 

I have been practicing dentistry in Edmonton for eleven years.  In 2004 I graduated with my DDS Degree from Dalhousie University and moved to Edmonton from Nova Scotia to attend post graduate training in general practice at the University of Alberta Hospital.  After a few years in family dental practice, I returned to to the University of Alberta for  3 more years of post-graduate training to become a specialist in Orthodontics.  I have been a Specialist in Orthodontics in Alberta since 2010. 

 I am a wife and a mother, in addition to a professional with a career to tend.  I know the challenges that adults face in coordinating and providing for all of the needs of their families as well as themselves.  Balancing work and responsibilities, while making time for rest and rejuvenation is merely a dream for most of us.  Where I wish to help is by providing service to you in the most efficient and reliable manner possible, ensuring you are fully equipped with the knowledge and tools to make informed choices appropriate for you.  

Thank you for taking a moment to get to know me.  I very much look forward to getting to know you!

Paul R, Business Manager

Hi there, my name is Paul.  I am proud to be part of this service minded team.  I am amazed daily by the incredible transformations that are produced in our office.  The transformation that some of our patients undergo are nothing short of incredible and it is great to be a small part of that journey.  My primary role is to ensure our overall customer service remains top notch and that our team provides everything we can to meet the needs of everyone who comes through our doors.

I bring a unique background and skill set to the Simply Orthodontics team.  While I have learned much about the dental and orthodontic fields, I come from a varied business and human resources background.  A graduate of the NAIT Business Management program, I have been fortunate to work in a variety of roles, managing great teams and ensuring the best possible customer service.

Away from the office I love cars, hockey and working with technology.  The most important aspect in my life though is my two crazy sons and beautiful wife.  Family is the single most important thing to me, and I'm happy to be part of the Simply Orthodontics family.
