Thomas R. Froning, DDS, D.ABDSM
- Denver’s Qualified Sleep Dentist
- Treating Sleep Disordered Breathing
After helping hundreds of his dental patients overcome sleep-related breathing disorders, Dr. Froning decided to focus exclusively on sleep and established Sleep Center of Colorado in 2019. He earned his Qualified Dentist designation from the American Academy of Dental Sleep Medicine, and in 2020 became a Diplomate of the American Board of Dental Sleep Medicine.
Dr. Froning is a strong advocate of alternatives to CPAP and treating OSA through Oral Appliance therapy because of his own personal experience, “As an extremely healthy person, I was shocked when I had a heart attack 8 years ago so naturally I began researching and learned that sleep apnea is a big contributor to cardiac health. I also discovered that oral appliance therapy is a recommended treatment for cardiac care. So I started wearing the appliance and immediately felt stronger and had more energy. At that moment, I knew I wanted to treat snoring and sleep apnea so that I could improve people's overall well-being and in some cases, even save people’s lives.”
He and his team are committed to providing the highest level of patient care and commit to hundreds of hours of continuing education every year in order to continue exceeding national standards for successful sleep apnea and snoring treatment with CPAP alternatives.
Dr. Froning lives in Littleton and enjoys climbing Colorado’s Fourteeners, skiing, fishing, and traveling, as well as spending time with his family.

In 1992 Dr. Sall began private practice in Syracuse, NY as an Otolaryngologist and Dentist with an emphasis on TMD, Orofacial Pain, general Otolaryngology, and the surgical and medical management of sleep disorders. In 2000 Dr. Sall earned an MBA from SUNY Binghamton with an emphasis in health care. In 2012 Dr. Sall became board certified in Sleep Medicine in order to expand access to people seeking alternative non-surgical solutions to snoring and sleep apnea.
Currently, Dr. Sall is the CEO of Sleep Center of CNY and since 2000hehas delivered Oral Appliance Therapy to over 5000 patients. In June 2018 Dr. Sall was named the Medical Director of ProSomnus Sleep Technologies with the role of increasing physician acceptance of Oral Appliance Therapy. Dr Sall joined BetterNight in February 2020 as a sleep physician providing Telemedicine sleep medicine consultations. He holds medical licenses in 42 states. He relocated to Scottsdale, Arizona in April of 2024 and loves how his role with Sleep Center of Colorado offers more time to spend with his daughter, her husband and grandchildren.
When Dr. Thomas Froning approached him about joining their team as medical director, it was an opportunity he couldn’t resist. His training and expertise allow the unique model of incorporating an Otolaryngologist and Sleep Physician inside an established dental sleep medicine practice to provide the most thorough and comprehensive treatment of patients with snoring and sleep apnea. He could not be happier to join this established practice and be an integral part of expanding their scope of practice in the Denver metro area.
