About Us

The IAOS Team combines decades of experience in the sleep world with an unmatched dedication to Member Success.

Avi Weisfogel


In 1999, he founded Old Bridge Dental Care in Old Bridge, NJ, a dental office he operated for more than 15 years. While running this practice, Dr. Weisfogel began to learn more about sleep, sleep disorders and how to treat them. Eager to explore how he could make a difference in the world of sleep, he spent countless hours trying to implement sleep apnea treatment within his dental practice using traditionally-taught methods. But in using these methods typically taught at sleep courses, he failed to make it a meaningful part of his practice.


Brandon Hedgecock


Dr. Brandon Hedgecock is the founder of Sleep Better Austin, a multi-location sleep-only practice in Austin, TX. Despite being a Diplomate of multiple organizations, investing thousands of dollars into marketing, and developing relationships with dozens of sleep doctors, Brandon was unable to make sleep a viable part of his practice. Just 2 years after joining IAOS, Brandon crossed the 50 appliances per month threshold and never looked back. Today, Sleep Better Austin has 4 locations and is rapidly growing. As a coach, Brandon helps dentists focus on the methodical growth of their sleep practices.

Chad Denman


Dr. Chad Denman opened four successful dental practices just eight years after graduating dental school. Despite lofty collections numbers, he was burnt out and desperate for a change. Within the first 60 days of joining IAOS, Chad was able to install a management program in a physician’s office and see 20 patients per month. Today, Sleep Cycle Centers have 3 locations and are on a rapid growth trajectory. As a coach, Chad helps dentists leverage telemedicine to streamline the process of getting physician-diagnosed patients in the door.


Max Kerr


Dr. Max Kerr is a partner with Dr. Brandon Hedgecock at Sleep Better Austin in addition to their two successful dental practices. Max was skeptical when Brandon joined IAOS and did not join him in his journey. But once Brandon began to see success, Max was the obvious choice to help Brandon continue to grow Sleep Better Austin. As a coach Max helps dentists with hiring, team building, and operations.
