About Us

Dr. Joseph Sarkissian studied microbiology at the University of Alabama. He then attended the dental school of the University of Goettingen in the former West Germany, where he graduated in 1989.

Over the next eight years, he practiced dentistry on the Mediterranean island of Cyprus. During that time he trained in homeopathy, completely abandoned the use of amalgam (mercury) fillings, and expanded his knowledge of the biological aspects of therapy.

In 1998, he moved to Los Angeles and received his license to practice in California. He currently owns a state-of-the-art biological dental practice in Glendale, California.

Dr. Katherine Dumoulin

 We are delighted to welcome Dr. Dumoulin to our practice. Her commitment to whole-body health, preventive care, and relationship-centered dentistry aligns beautifully with the philosophy that has guided our office for many years. We are confident that her compassionate approach, extensive training in an Ivy League dental school, and passion for biological dentistry will make her a wonderful addition to our team and a trusted partner in your family’s oral health journey.

Dr. Dumoulin grew up in Maine and went on to study at the University of Michigan before pursuing her doctorate in dentistry at Columbia University. Her path to dentistry was shaped by her own personal health journey, through which she witnessed firsthand how reactive our healthcare system can be, and how rarely prevention is prioritized. That experience sparked a deep passion for a different way of practicing, and she entered dental school already knowing that biological dentistry was where she was headed.

Dr. Dumoulin is drawn to the full scope of what holistic and biological care has to offer, including biomimetic restorations, ozone therapy, and mercury-free dentistry. She believes that the mouth is inseparable from the rest of the body, and that truly caring for a patient means looking at the whole picture.

Above all, her favorite part of being a dentist is the relationships she builds with her patients. She loves getting to know the people in her chair and believes that genuine connection is at the heart of good care.

She is a member of the IAOMT (International Academy of Oral Medicine and Toxicology) and the IABDM (International Academy of Biological Dentistry and Medicine).

Ester Sohn

Esther Sohn RDH

Esther Sohn joined our team in 2019. She has been amazingly popular among our patients and has implemented many of our holistic approaches to our dental hygiene and prophylaxis programs. She implements ozone gas and laser decontamination in her routine dental cleanings and expertly addresses most periodontal issues utilizing non-invasive and biological protocols. The most common reaction of our patients after their first one-hour session with Esther includes the phrase “This is the first time I experienced such a thorough cleaning”.

We will hereby let her introduce herself in the following paragraph:

“My name is Esther and I am a dental hygienist. I graduated from LLUSD in 2003 and I come from a family of dental and medical professionals. I believe in educating people about their oral health so that they can make informed decisions. I value prevention before treatment, simplicity, and consistency. Life gives us many reasons to smile and I’m here to help maintain that smile.”
