Originally born in Simcoe, Ontario and raised in London, Ontario, Dr. Lever earned both his Bachelor of Science (1978) and Doctor of Dental Surgery (1982) from the University of Western Ontario. In 1984, he established his practice in Don Mills at the Don Mills Shopping Centre—now the Shops at Don Mills—where he continues to serve the community today.

His goal is to provide patients with comfortable, conservative treatment while helping them understand their oral health and the options available to achieve a healthy, confident smile.

Dr. Dennis Park
Dentist
Dr. Park is passionate about combining modern dental technology with a patient-centered approach to help people achieve healthy, confident smiles. He earned his Doctor of Dental Surgery from the University of Don Mills and began his career serving the wonderful community of Orillia, where he spent several years honing his skills across all areas of dentistry while caring for patients of all ages. He later returned to Don Mills to join Dr. Lever, sharing a vision of providing comprehensive, long-term family dental care.
Before pursuing dentistry, Dr. Park graduated as Valedictorian from McGill University, reflecting his strong commitment to academic excellence and innovation. His interest in advancing the field of dentistry has led him to be involved in early startup work related to Invisalign technology and to play a key role in securing a Canadian Institutes of Health Research (CIHR) grant supporting research focused on preventing tooth decay.
Dr. Park is deeply committed to continuous learning and staying at the forefront of modern dentistry, regularly pursuing advanced training in digital dentistry, evolving treatment techniques, and the latest dental technologies. His goal is to provide care that is not only precise and effective, but also comfortable and tailored to each patient’s long-term oral health.
Outside the clinic, Dr. Park enjoys reading, volunteering, and giving back to the community. When he’s not caring for patients, you’ll often find him relaxing with a good book or spending time with his two cats.
