Meet Dr. Leonard (Lenny) Arenson


Dr. Lenny graduated from the University of Witwatersrand Dental School in Johannesburg, South Africa in 1979. After gaining valuable experience as a dentist in the military, teaching at the University of the Western Cape Dental School, and founding his own dental practice in Cape Town, he relocated with his family to Toronto to enhance patients’ smiles. He has been in practice for 30+ years.


Ever since becoming a dentist, Dr. Lenny’s philosophy has been to provide patients with optimum dental health. He’s passionate about what he does and puts an emphasis on getting to know the people he’s helping. At Arenson Dental & Associates, you become a part of our family!

Home Life

When he isn’t making patients smile, Dr. Lenny enjoys spending time with family and friends. He is an avid sports fan and experienced runner who has finished marathons in New York, Boston, and beyond. His daughter, Loren, is a dentist at the practice.
