Long before Dr. Floyd Kasch became a dentist, he knew what it felt like to be afraid of one.
As a child, Dr. Kasch had painful and frightening experiences at the dentist. Instead of becoming easier with time, dental visits became increasingly difficult. He remembered worrying about an appointment for an entire week beforehand and being unable to sleep the night before.
Years later, those experiences would profoundly influence the kind of dentist he chose to become.
That simple idea became the foundation of a dental practice that has served generations of families in the Portland-Vancouver area: providing excellent, comprehensive dentistry while doing everything possible to make patients feel comfortable, respected, and safe.
Today, more than five decades later, that philosophy remains at the heart of Sleep Dentistry.
“I knew what had bothered me, so I was trying not to create that in anybody else.”
— Dr. Floyd Kasch
Dr. Kasch was born in Nampa, Idaho, but his family moved to Southeast Portland before his first birthday. Portland became home.
Before entering dentistry, he worked with his father in the family’s commercial real estate development business. But Dr. Kasch realized his kind and relaxed nature was not a good fit for the hustle and bustle of commercial construction. He felt that something in the medical field that would allow him to use his craftsmanship skills aligned with his personality much better. Upon reflection, he decided dentistry would be an ideal choice and started on his career path.


Dr. Kasch earned his DMD from the University of Oregon Dental School,
the predecessor of today’s Oregon Health & Science University School of Dentistry.
His education did not end with dental school. Throughout his career,
Dr. Kasch had an intense interest in learning new techniques and
expanding what he could offer his patients. Extensive continuing
education became a lifelong pursuit.
There was a practical reason for that breadth of knowledge.
Dr. Kasch knew that patients who had finally worked up the courage
to trust one dentist might find it extremely difficult to start
over with an unfamiliar office for another procedure. Whenever
practical, he wanted his patients to be able to receive the care
they needed from people and surroundings they already knew.

Dr. Kasch's interest in sedation dentistry began almost immediately after dental school. In October 1972, he completed continuing education in “Intravenous Psychosedation” and "I.V. Analgesia" through the University of Oregon Dental School. His training continued over the following years.
By June 1975, he completed formal postgraduate lecture and clinical training series in both inhalation and intravenous sedation through the Northwest Analgesia Research Group and the University of Oregon Dental School's Continuing Education Department.

Dr. Kasch opened his dental practice in 1973 near the corner of SE 192nd Avenue and Stark Street in Southeast Portland. The first location was intended to be temporary, as a permanent dental facility was already being built nearby on Stark Street between SE 192nd and 194th Avenues.
His father built the building specifically with Dr. Kasch’s dental practice in mind, and Dr. Kasch helped influence its design. In 1974, the practice moved into its new permanent home.
The office opened with six private treatment rooms, a substantial dental facility for its time.
Private treatment rooms were an intentional choice. Rather than treating patients in an open clinical environment, Dr. Kasch wanted people to have privacy and a quieter, more personal experience—an approach that continues throughout Sleep Dentistry’s offices today.

From the beginning, this was a family dental practice—but one with a particular understanding of people who were afraid of dentistry.
Dr. Kasch frequently used the words “Gentle Dentistry” to describe his approach. Nitrous oxide was readily offered to apprehensive patients, and oral sedation provided another option for patients who needed additional help relaxing.

During the early years of his career, Dr. Kasch made IV sedation available to patients on a limited basis. At the time, however, he did not make the option widely known, and relatively few patients received IV sedation. Not yet realizing how significant the need for this type of care really was, he later stopped providing IV sedation for a period of time. Sedation was only part of the philosophy.
Dr. Kasch believed the dentist, staff, surroundings, and manner in which treatment was provided all influenced a patient’s experience. Treatment rooms were individually decorated and deliberately made more interesting and inviting than the sterile clinical environments common at the time. Patients weren’t rushed simply because they were frightened. Patients weren’t judged for being afraid.
Some patients came in after avoiding dental treatment for 10 or 20 years—or even longer. For these patients, getting through the door could be an accomplishment in itself.
The goal wasn’t simply to get them through one appointment. It was to help them regain their oral health and, over time, change what going to the dentist meant to them.

In 1981, The Oregonian featured Dr. Kasch and his Rockwood dental practice, focusing specifically on his approach to helping people who were frightened of dental treatment.
The article described an office quite different from the stereotypical dental practice of the era. Treatment spaces included plants, artwork, music, and individually decorated rooms. One room was even known as the “Jungle Paradise.”
The decorations were memorable, but the philosophy behind them mattered more: make the dental office feel less frightening.
At the time, much of the practice still served families from East Portland and Rockwood. As its reputation grew, however, patients began coming from throughout the Portland metropolitan area. Some drove hundreds of miles—and occasionally people would fly in from out of state—just to receive his care.









What began with one dentist and six treatment rooms in East Portland has grown into a three-location dental practice serving Portland, Vancouver, and Camas.
Today, Sleep Dentistry encompasses approximately:
All three locations provide sedation dentistry, and all continue to provide comprehensive family and general dental care.
Our patients come to us for routine exams and preventive care as well as restorative dentistry, dental implants, surgical treatment, full-mouth rehabilitation and other complex dental needs. For patients who need help with anxiety, sedation options allow treatment to be tailored to their individual needs.
Most of our patients live in the Portland-Vancouver area, although some still travel considerable distances for care—just as patients did during Dr. Kasch’s years in practice.
