Williams Lake Dental has been providing quality, caring dentistry to area residents for more than 40 years. Whether you’ve been a patient since we first opened our doors or visiting our clinic for the first time, the professional staff at our Cariboo dental centre offer you unsurpassed service and leading-edge dentistry.


Soon after receiving his Doctorate of Dental Medicine degree from the University of Alberta in 1969, Dr. Elmer Thiessen moved to Williams Lake and established his practice – with the goal of providing comprehensive dental services to area residents. Operating out of the same building at 440 Comer Street for more than 40 years, Dr. Thiessen’s Cariboo dental centre has a long history of quality dental services, combined with a patient-centred approach to treatment.

In 2015, Dr. Thiessen transitioned his practice to Dr. Christopher J. Ciriello – a skilled dentist from Ontario with more than 10 years of experience. While Dr. Ciriello changed the clinic’s name to Williams Lake Dental, patients will continue to find the same high levels of quality, caring dentistry and service they have come to expect when they visit 440 Comer Street.

Our clinic has recently been renovated to include an array of today’s leading-edge dental equipment– as well as a variety of modern conveniences. It’s all designed to offer you the most effective treatments you will find, delivered with the highest levels of comfort.

When you visit Williams Lake Dental, you’ll be greeted by many of the same friendly faces you’ve seen here for years. At the same time, you’ll meet some of the new, highly-trained staff who have joined us recently. Combined, they form a leading team of professionals dedicated to offering you a friendly environment and top-quality dentistry.


Our commitment to you means we will always:

  • We will use only the most modern dental equipment available to provide you with the comfortable and effective treatments.
  • Our team will work together with you to develop a lasting relationship and establish a plan for your best overall dental health in the long-term.
  • We will offer a team of leading dental professionals who are dedicated to regularly updating their skills and providing only the best of modern dental services.
  • Our Cariboo dental centre will provide an inviting and friendly environment, with staff who work hard to make your visit a pleasant and smooth experience.


All our dentists and hygienists have extensive experience in their field, backed by certifications from highly regarded dentistry schools. Inspired by Dr. Christopher J. Ciriello’s commitment to excellence, our dental professionals take regular sabbaticals to study and keep their skills on the leading edge of the dental field. Our professional office staff work together with our dentists and hygienists to offer you a seamless experience, complete with short wait times, predictable pricing and quality patient support.
