Our Team of Great Portland Dentists


Dr. Kasch, DMD

“Our philosophy is to treat our patients like our own family, with gentle, friendly care. Whatever we can do to make your visit more comfortable and to give you a brighter, healthier smile, we’ll strive to make it happen.”

If you have any apprehension and anxiety about going to the dentist, Dr. Kasch understands. He grew up with those exact feelings, and his childhood experience inspired the guiding principles of Sleep Dentistry of Portland.

When Dr. Kasch was seven years old, he had an unpleasant dental experience that left him very apprehensive about going to see the dentist. When he himself became a dentist, he vowed to create an environment of peace and comfort to help calm anxious patients.

The Sleep Dentistry of Portland office is designed to put patients at ease as he provides gentle and comfortable dental treatment.

Dr. Kasch completed his undergraduate and pre-dental education at Lewis & Clark College and is a graduate of Oregon Health & Science University School of Dentistry here in Portland, Oregon.

Fully trained in the latest procedures, he uses state-of-the-art technology to provide a comfortable experience and keep our prices among dentistry’s most affordable.

Dr. Kasch is active in professional organizations including the American Dental Association, Oregon Dental Association, and Multnomah County Dental Association.

He also donates his time to Dentistry From the Heart, providing free dental care to those who may not have been able to afford and receive dental treatment otherwise.

When not treating patients, Dr. Kasch enjoys collecting antiques, gardening, and spending time with his grandchildren.
