Trina Bourgeois - President

I am what you would call a veteran RDA; I have worked in the dental field for 30 years ~ now. I still enjoy all aspects of dentistry and my current job working in an Endodontic practice.  I have upgraded to include the scaling module,  although in endodontic practice I'm not practicing any scaling, haha!

I am certainly not new on the Board of Directors but have enjoyed the various committees I have encountered within the Board in the last 6 years +.  Having this experience is why I decided to put my name in for the President role.  It is a big undertaking but we all need to do our part to manage our association.  It is a great experience and has offered insight into many aspects to the process of our our profession from the inside out.

In my spare time I enjoy camping, traveling (when we can again) as well as motorcycling and vacuuming hair from my beautiful and fun, but hairy dogs!

I feel confident that I can lead the wonderful Board of Directors who offers their time and effort for whatever they are able to manage. It certainly takes a team to do what we do and we are always looking for new team players.

Thank you,

Trina Bourgeois


Heather Brownlee - President Elect

My name is Heather Brownlee and I have been a Dental Assistant for over 40 years graduating from RRC in 1977 with my Phase11 Dental Assisting Diploma, taking my Ortho Module in 1984 and Extended Duties in 2003.  

I became involved in our local and national Dental Assisting Associations 40 years ago serving on the then Winnipeg Dental Assistants Association and Manitoba Dental Assistants Association in many capacities.   I took an extended leave while I was raising my children becoming actively involved in both the MDAA and CDAA in 2007 when RDA’s in Manitoba became licenced under the MDA.    I along with a group of dedicated RDA’s  worked tirelessly to rejuvenate the Manitoba Dental Assistants Association to bring it to professional organization we have today representing RDA’s of Manitoba. 

I have served as a Board Member, President, Past President, and Secretary and presently am the President Elect for MDAA.

I serve as the MDAA Board member to the CDAA and I am presently the President Elect for CDAA.   I also serve on the Knowledge and Transfer Committee and By-Law and Governance Committees for the CDAA.

I am presently one of the CDAA Members on the CDAA. CDHA and CDA Healthy Workplace Group creating resources through a new website to help dental teams develop safe respectful workplace.

In my spare time I curl, bowl and walk for exercise, like knitting and doing different crafts for family and friends and hopefully in retirement will be able to start gardening both flowers and vegetables.  I enjoy spending time with my four grandkids and traveling across Canada by train with my husband to visit our kids who live in Vancouver and Halifax.

Going forward I look forward to represent RDA’s in Manitoba as CDAA advocates to have the Dental Assisting Profession reclassified through the National Occupational Analysis which will give us more recognition for our formal training.   I would also like to see Registered Dental Assistants represented from coast to coast.

Bev Girouard -Secretary

My name is Bev Girouard and I am the Secretary and the newest member of the Board for the Manitoba Dental Assistants Association. I have been a Dental Assistant for over 35 years. I graduated from Keewatin Community College (University College of the North) in 1985. I completed the Orthodontic Module in 1988, and the Dental Assisting Advanced and National Certification from the National Dental Assisting Examining Board in 1998.

I worked in private practice for over 25 years and am currently employed at the Gerald Niznick College of Dentistry where I provide assistance to the students and professional staff in the Main Clinic, Speciality clinic, the Medical Device Reprocessing and Radiology departments as well as the Graduate Pedodontic, Graduate Periodontic and Graduate Prosthodontic clinics.

I have been married to my best friend Henri for over 25 years and have 3 beautiful children Brandon, Sarah and Jordan. The newest addition to our family is Archie our Jack Russel Terrier.  In my spare time I enjoy camping, cycling, cooking, baking, knitting and gardening.  I am no stranger to adversity as my oldest son Brandon has Autism and believe that we need to be a voice for those who cannot speak for themselves.   It is for this reason that I have joined the Board of the Manitoba Dental Assistants Association and can be a strong voice and support for all Dental Assistants across our province.

Kind regards,

Bev Girouard


Tabatha Blais - Director

My name is Tabatha Blais and this will be my 3rd year sitting on the Board as a Director.  I am the representative for the Dental Assistant’s on the Infection Prevention and Control Committee. Infection control in the dental office is very near and dear to my heart and I take this role with the upmost respect when representing all RDA’s in Manitoba.

I graduated in 2007 for CDI College as well as obtained my Orthodontic module as well in 2007 at Red River College. I started my career in a small General Practice office, until 2018, when I decided to pursue an opportunity within a Periodontal/Prosthodontic office where I am currently the office manager.  Being an office manager, I am finding myself enrolling in all different types of seminars which benefits me in all aspects of the dental field. I always find myself eager to learn more!

When I’m not at the office or on Zoom calls, you can find me renovating, hiking, relaxing at the cabin and spending much needed quality time with my family and friends.

Duncan Stokes - Staff

I have several years experience in non-profit management, combined with many more working in communications and marketing. My career has included 20 years as a radio broadcaster (Thompson, Dryden, ON  and Winnipeg), terms managing the Snowmobilers of Manitoba (Snoman Inc.), and the Manitoba Eco-Network offices, as well as experience in the communications and marketing departments at Winnipeg Harvest (now Harvest Manitoba) and the MS Society of Canada (MB Division).

I embrace the challenge of managing the MDAA office and hope to utilize my talents and experience to help the association any way I possibly can.

In my spare time, I am a father, grandfather, son, brother and uncle among many other titles. I consider myself a ‘sports junkie’, especially for Winnipeg’s Jets, Blue Bombers and Goldeyes, as well as Valour FC. I am fascinated by animals, especially apes. I count dog and cat rescues as part of my family.

I was born, raised and have spent most of my life living and working in Winnipeg, I love the city. The mosquitoes, the extremes of hot/cold weather and even the jokes about Winnipeg are things I take in stride.

Everything I need to stay happy is in Winnipeg.
