I have had the pleasure of being a patient of Dr. Edwin Lewandowsk. I am a very nervous patient when it comes to dental work and they went out of their way to make me comfortable and answered any questions or concerns that I had. The office itself, is a clean, inviting environment and the entire team from the ladies at the front desk, the hygienist, to the Doctor, makes you feel at ease. I would highly recommend them!

Dr. Ed is awesome!!! He and his staff are professional, lovely (and HILARIOUS). His practice is the sole reason I have stayed up to date and proactive about my overall oral health. Would recommend to all family and friends.

The Best Dentist around Thornhill/GTA. I get my teeth cleaned there regularly. Just had a Root-Canal, didn't feel a thing...no joke. Dr. Lewandowski and his staff are extremely professional and kind. The staff really cares about their patients. I would recommend Dr. Ed Lewandowski and his team to Everyone!
