Our Team

Your healthcare family!


Since launching his family practice in February 2003, Dr. Miller and his entire healthcare team have worked hard to create a friendly, accessible environment for families with children, to seniors, and those with special needs.


When you walk into a place where people really and truly work in sync, you can feel it. Everything flows a little better and staff are happier. We love what we do—you’ll rarely see us without smiles on our faces!


Every member of our healthcare team is committed to lifelong learning and exceptional patient care, whether we are chairside with our patients, on the phone, or behind the scenes.


Here is our complete team lineup:



john-millerDr. John Miller,



Dr. Miller is a perfectionist for whom the very best result is the only option. “I want to provide every one of our patients with the best quality dentistry possible,” he says. “We make use of the latest technology and the entire team is dedicated to lifelong learning and to the highest levels of patient care, service and communications.”


Dr. John Miller learned the skills he uses today at the University of Western Ontario and the Las Vegas Institute for Advanced Dental Studies (LVI). He honed them in a yearlong residency at the Hospital for Sick Children and in the practice of long-time Collingwood dentist Dr. Farrell Anderson.


Dr. Miller was born and raised in Mac Tier near Parry Sound, Ontario. He was a competitive tennis player throughout his teens, which led him to Collingwood for the first time. The decision to practice in Collingwood was based on Dr. Miller’s lifelong commitment to an active lifestyle and his desire to find a vital community in which to live and work.


Upon moving to Collingwood in June 2000, Dr. Miller forged links in the local health care community. He started up a dental study group and obtained operating privileges at the Collingwood General and Marine Hospital where he treats young children and other patients with sedation.


Outside of his professional life, Dr. Miller is active in the Collingwood community, supporting a wide variety of community organizations. He is proud to be a charter member of the Rotary Club of Collingwood-South Georgian Bay and an active member of CrossFit Indestri Collingwood.



Sam-GoodmanDr. Sam Goodman,



Dr. Sam Goodman was born and raised in Markham, Ontario. Sam’s passion for oral health was sparked at a young age as he grew up watching his father do what he loved most – dentistry. Sam graduated from McMaster University with an Honours degree in Health Sciences and a Master’s of Business Administration. He went on to study dentistry and graduated with distinction from Western University.


Sam is an avid soccer player, playing for Canada at the Maccabiah Games in Israel and representing Ontario at the Canadian Nationals. He was also a member of the McMaster Marauders varsity soccer team, so sports is a big part of what he loves to do in his spare time. He also enjoys snowboarding, skiing, hiking, scuba, and basically any sport he can find time to play.
Sam spent the summer of 2014 providing needed dental outreach care to communities in Tanzania, Africa. He hopes to make outreach work an integral part of his dental career.


Sam and his wife Shannon, son Tobin, and dog Tommy are excited to call the Blue Mountains their home and are looking forward to becoming involved in the community. Growing up skiing in the area, Sam has developed an appreciation for the sense of community and natural beauty that the Blue Mountains area has to offer.
