Meet the Dentists

At Thornhill Smiles, we believe great care starts with genuine connection. Our dentists combine clinical expertise with a warm, friendly approach — so every visit feels a little more comfortable, and a lot more personal.

Dr. David Goldberg, DDS

Dr. David Goldberg was born and raised in Toronto. He graduated from the Health Sciences program at McMaster University, and received his Doctor of Dental Surgery from Schulich Dentistry at Western University. David went on to complete his Advanced Education in General Dentistry residency at the University of Connecticut in the United States.

David enjoys all aspects of dentistry, and prides himself on offering his patients a wide range of services, including implants, root canals, wisdom teeth removal, complex surgeries, prosthetics, Invisalign, pediatrics, and cosmetic dentistry. He is a proud member of the AACA, ensuring the best Invisalign results for all his patients. Due to his vast experience and training in all aspects of dentistry, he is uniquely positioned to offer a diverse and multi-disciplinary approach to dental care. Patient satisfaction is David’s number one goal, and he feels truly fulfilled when he sees his patients’ lives transformed through their new smiles. In addition, David always strives to maximize the patient experience, and is always keeping up to date on innovative technologies and procedures.

In his free time, David enjoys plugging into the world of popular culture and current events, and is an avid consumer of news, sports, history, and politics. He also enjoys keeping active, travelling, giving back to his community, and spending time with his wife and two daughters.

Dr. Ina Ionescu, DDS

Dr. Teodora Cristina Ionescu — known to her patients as Dr. Ina — sees dentistry as more than just a science. For her, it’s an art form that blends precision with creativity, vision, and harmony. She believes every smile is unique, and her goal is to create personalized, long-lasting results that not only look great but also support oral health and function.

Originally from Romania, Dr. Ina discovered her passion for aesthetic and reconstructive dentistry while assisting her husband in his dental laboratory. That early hands-on experience shaped her approach and sharpened the artistic eye she brings to every smile makeover.

Dr. Ina completed her dental education at McGill University’s Faculty of Dentistry in Montreal. Since moving to Toronto, she has practiced as an associate in multiple clinics, offering comprehensive care tailored to each patient’s needs. Her ongoing commitment to learning has led her to complete numerous continuing education courses in prosthodontics, orthodontics, and restorative dentistry.

Fluent in Romanian, English, Spanish, German, and French, Dr. Ina enjoys connecting with people from all backgrounds. Outside of dentistry, she loves traveling (especially to sunny destinations), watching movies and shows, and spending quality time with her family.
