Harold Isaacs, DDS & Johanna Schaeffer, DDS
Dr. Schaeffer and Dr. Isaacs are the owners of Aldente Dentistry. They are a husband-wife team of Waterdown dentists who have been serving their community since 2008. They began helping the original dentist until they purchased the practice in 2009. The Waterdown dental office opened in 20024.
“We love our profession! We chose to practice general, family dentistry because of the wonderful relationships we get to build with our patients. It is truly rewarding to see our patients’ self-esteem and confidence be uplifted with a beautiful smile, or to know that they can finally enjoy their meals without pain. We love the fine balance of art and science required to provide quality dental treatment; it is challenging and rewarding to be able to improve a patient’s health, function, and esthetics. Most of all, we love taking care of our family of patients and earning their trust. Our patients’ health and happiness is something that we never take lightly.”
—Dr. Schaeffer & Dr. Isaacs

Education and Experience
Dr. Schaeffer, Dr. Isaacs, and Dr. Ortega attended the University of Toronto in the early ’90s for their undergraduate education and continued on to the University of Western Ontario where they earned their Doctor of Dental Surgery degrees.
Dr. Isaacs also has a Master’s degree in Anatomy and Cell Biology and was a high school math and science teacher for several years before deciding to become a dentist. During their years in dental school, our dentists earned awards in the fields of periodontics, endodontics, and restorative dentistry, as well as community involvement. All three dentists were accepted into highly competitive dental residencies, at Sunnybrook Hospital in Toronto, and the London Health Sciences Center in London, where they refined their skills in oral surgery, sedation techniques, and the proper management of medically compromised patients. They practiced dentistry for many years in dental offices in London, Toronto, Mississauga, Bolton, and Richmond Hill before setting their professional roots in Carlisle. In 2024 they relocated the dental practice to Waterdown.
Continuing Education
“Continuing education is not only a requirement for dentists, it is also the key to helping us stay on the cutting-edge of technology and techniques that benefit our patients. Dentistry is constantly changing as research and development leads to better materials and easier ways to perform dental treatment. We enjoy learning because it keeps us sharp, challenged. We are consistently pursuing further training in order to be excellent clinicians for our patients. Our patients deserve nothing less.”
