About Us


After earning my Honours Bachelor of Science in Pharmacology and Physiology from the University of Western in 1981, I continued my studies at Western and earned my doctorate from the School of Dentistry in 1989. From there I  completed an Advanced General Dentistry (AGD) residency at the United States Dental Activity in Fort Knox, KY. Becoming Board Certified in 1993 as an Advanced General Dentist with the Federal Services Board of General Dentistry and the American Board of General Dentistry gave me the skills and expertise necessary to complete a successful 26-year military career with the Royal Canadian Dental Corps (RCDC).

Military Career

Because the RCDC supports our military personnel both at home in garrisons and while deployed overseas, having the knowledge and skills obtained during my AGD residency was invaluable. Bridging the gap between general dentists and specialists is vital to our Armed Forces serving in remote or war-torn areas. I was honoured to use this understanding of advanced treatment options to keep these brave men and women free from pain and dental issues while serving their tours. As I anticipated my RCDC retirement in 2003, my goal became to offer these same services as a civilian, and I opened West Ridge Family Dentistry in Orillia in 2003.

West Ridge Family Dentistry

My long-held belief in a comprehensive approach to dental care has carried into my dental practice today. From an in-depth oral health examination to diagnosis and treatment planning, my focus is on giving your family coordinated treatment that meets all of your needs. You could think of me as a quarterback for your care, ensuring that all services, including sedation or general anaesthesia, meet your needs and desires for a happy, healthy smile, and meet my standards for your oral healthcare delivery.

Away from the practice, I enjoy playing the trumpet in community bands, long-distance running, and SCUBA.

Meet Our Team


Sarah, Office Manager / Certified Level II Dental Assistant

I’ve been with West Ridge Family Dentistry since 2005, combining my Level ll Dental Assisting certificate from Georgian College and my Health Administration diploma from Conestoga College. While I do love the administrative part of my job, I take my greatest joy every day from meeting new people and helping each of our patients feel as comfortable as possible during their treatments.

Away from the practice I enjoy travelling with my husband, scuba diving, baking, and cake decorating. I also remain actively involved with the Dental Advisory Committee at Georgian College.


Erin, Treatment Coordinator/Administrative Manager

I’ve been working with the amazing team at West Ridge Family Dentistry since 2013 and I love that I have the opportunity to interact with so many fantastic patients! My focus is on ensuring that your experience with us is positive and educational, and I am thrilled with any opportunities to answer your questions about any of your treatment options. I’m also certified to help with tobacco cessation to support your dedication to excellent oral – and overall – health. 

Away from the practice, I enjoy spending time with my husband Andy, who is the reason I moved here from Sydney, NS. We have two crazy Bengal cats named Indy and Rossi who are a joy to be around. In my free time, I enjoy cycling, playing piano and singing, and tutoring French and math. 


Roger, Chief Registered Dental Hygienist

After being a dental assistant, I decided that I wanted a more active role in preventing dental diseases, rather than treating them, so went back to school and earned my Dental Hygienist credentials in 2005, the same year I joined the team at West Ridge. I love the multi-disciplinary approach and the many ways we help educate our patients about prevention and treat any issues that do occur – especially because our patients are often the same people I’ve grown up with here in Orillia.

Away from the practice I enjoy motorcycles, hiking, camping, being on the water in a canoe or kayak, and working out at the gym. I one day hope to see all of Canada and recently ticked off a trip to the Arctic Circle from my bucket list!


Kristen, Registered Dental Hygienist

I’ve been working with the team at West Ridge Family Dentistry since 2014 and most enjoy helping my patients see the connection between their oral health and their overall health. Since earning my dental hygiene credentials from Georgian College in 2014, my dental healthcare philosophy has remained the same: get informed, make decisions, and stay on track. I love that my job as a hygienist lets me not only inform my patients at how they can improve their oral health, but to also help them stay on track after making the decision to make changes.

Away from the practice, I enjoy water sports in the summer and skiing in the winter.


Leann, Dental Certified Level II Assistant

You could call me a bit of a fixture at West Ridge Family Dentistry – I’ve been working alongside Dr. Collins since he opened the practice in 2003! As a dental assistant my chief concern is to help you feel comfortable throughout your appointments, and I particularly enjoy assisting surgical procedures. I love the variety of working on different types of cases every day – from basic restorations to root canals and wisdom teeth removal. It certainly keeps things interesting!

When not assisting at the practice, I enjoy spending time with my family and volunteering with Scouts Canada.


Lynette, Dental Certified Level II Assistant

I’ve been working with West Ridge Family Dentistry as a dental assistant since 2017. With my Dental Assisting diploma and HARP certification, you can find me assisting chairside and taking your dental x-rays – they’re more comfortable and convenient than ever!  With my focus on ensuring you feel well cared for and understand every aspect of my care, I’m here to answer any questions you may have so that you feel well informed and at ease throughout your visits.

Away from the practice, my partner and I have a son and we’re thrilled to have gotten out of the busy city. It’s my dream to one day own a hobby farm, so rural living is definitely the right choice for us!


Jessica, Dental Certified Level II Assistant

Mine is one of the smiling faces you see when you visit Dr. Collins and Dr. Piercy. As a dental assistant, my main focus is on ensuring you are at ease throughout your visits, so if there is anything I can do to assist you with your care, do let me know. I love getting to know new people and helping you feel good about your smile.

Away from West Ridge Family Dentistry, where I’ve been helping people smile since 2016, I enjoy running, cooking, and travelling, as well as spending time with my dog Chloe.


Lisanne, Intake Specialist

Making sure you feel welcome and at ease at every visit is my first priority when you visit West Ridge Family Dentistry, and I’ve been doing it with a smile on my face since 2015! I love people and when I can help someone feel at ease who may be nervous or in pain is one of the most fulfilling aspect of my job. I also have a dental hygiene diploma and a Bachelor of Adult Education, so if there are any dental questions you have, please do ask me!

I grew up in Mississauga and have quite enjoyed calling Barrie home since 2005 where I am closer to the ski hills and beautiful Georgian Bay for sailing. In my spare time, I am working towards my black belt in taekwondo and enjoy spending time with my partner Phil, my daughter Meghan, and our Himalayan cat, Bella.


Emily, Intake Specialist

As an Intake Specialist since 2014, I owe most of my dental education to my father, Dr. Collins. His passion for what he does and overall happiness about helping people made me want to do the same! When I’m not at West Ridge Family Dentistry helping our family of patients access the care they want and need, I’m a volunteer firefighter and am working on my Criminology degree. 

When I do have some free time, I love to spend it with my boyfriend Alex, who is an amazing iron worker. I stay fit by working out and access my creative side by playing piano, dancing, and singing in the car.
