Hayven Team

Hayven Dentures is a team of dental professionals where their love and dedication in providing long-lasting and beneficial denture treatments really shine.

Our goal is to be there with you at every step of the way from the first meeting to the very end of getting comfortable with the dentures as the care and maintenance play a big part in making the most out of your denture investment and investment in yourself.

The team at Hayven continually strive to not only learn new techniques, skills, or other advancements to improve their clinical and laboratory craftsmanship but they constantly review and practice the things they have learned previously to provide consistent quality work for all patients.

Know Your Denturists

Hayes Leung, MESc, DD

Hayes has a strong affinity to the world of dentistry ever since he was at the age of 8. He had frequent visits not only for dental hygiene but due to his love for eating and being an avid candy muncher, he had many occurrences of cavities. He has been submerged into the dental environment, allowing him to see the beauty and enjoyment in helping others smile and eat again.
After obtaining his undergraduate degree of Honors Bachelor of Science in Neuroscience and Integrative Biology (Specialist), he continued his studies with a graduate degree of Environmental Science. Through facing hardships at the time, he looked back on life to see where he would truly be happy and Denturism was the answer. He attended George Brown College and graduated at the top of his class which was later recognized with the “A.J. (Jim) McGuire Memorial award” presented by the Denturist Association of Ontario.
Ever since graduating from school he has continued his studies in pursuit of improving his clinical and technical skills of constructing dentures to improve the quality of life for the wearer. Through his dedication to all who he treats and cares for, he searched high and low for solutions to the common denture problems that arise. Hayes is officially the first denturist in Ontario to obtain both certifications to practice Suction Effective Mandibular Complete Denture (SEMCD) and CQR Denture techniques. These two certifications improved his techniques which helped him provide dentures that stay in the mouth without the use of denture glue or dental implants whilst allowing the wearer to have a biofunctional bite.
As a founder of Hayven Dentures, he has developed the practice to have an ideology of, “providing high quality dentures to improve or maintain the quality of life for the wearer” and to “stay on top of new techniques and concepts to provide a suitable treatment options that are customized to the denture wearers.”

Christine Twardawsky, CDA Level II

Christine started her dental career immediately after graduating high school by attending Niagara College in Welland. She was inspired to choose a career in the dental field by her sister, who, at that time was working in a dental office.
After graduating from Niagara College, she was employed as a Level I dental assistant for several years until she left for a short time while raising children. Christine returned to working in a dental office and upgraded her skills to a Level II dental assistant by returning to college where she earned the top mark in her class on the final exam. Christine is a member of the Ontario Dental Assistants Association and has continued to work and gain experience as both a dental assistant and receptionist while participating regularly in continuing education in the dental field.
In her spare time, Christine participates in line dancing classes, loves to try cooking something new, and spends time with her chocolate lab, Sadie.
At Hayven Dentures, Christine looks forward to welcoming you at the front desk and working alongside her very skilled and knowledgeable denturist team who are dedicated to advancing their techniques in creating customized dentures just for you.

Vivan Nguyen, HBSc, DD

Vivan is also a founder of Hayven Dentures and the name “Hayven” really comes from the two founders (Hayes and Vivan). Through a lot of time thinking about the ideology, and practice of the clinic, the name perfectly represents this. From the actual word, haven which means a place for safety, shelter, oasis, or retreat, Hayven Dentures upholds this by providing a clinic that helps patients feel safe, confident and proud that their oral health and smile with dentures are being taken care of.
