About Assistance On Call, Inc.


Colorado’s LEADER in Dental Employment.









 After working for a dental office herself (from 1974 – 1983), and seeing the inconsistencies and problems in the industry, Barb Sumner (future founder and CEO of AOC), envisioned a better way. She set out to change Colorado’s dental staffing industry on both sides of the fence (from the dental office point of view AND the employees point of view).

In 1983 she did just that, and Assistance on Call (or AOC for short) was born.

AOC’s inception was in a 700-square-foot house in south Denver. A picnic table was the only desk in the ‘office’ and it held a rotary dial phone. The only other technology AOC used back then consisted of a reel-to-reel answering machine, a manual typewriter, and a radio shack entry level computer, with a cassette tape back up.  The infancy stage of building a business is never easy, and those lean times lasted 10 years.

But over the years, and by doing things right – AOC got bigger and better.

Assistance On Call boasts a one of a kind proprietary scheduling software system, designed by Barb and a complete system of networked computers, state of the art phone system, an integrated website.

Assistance On Call is located in a beautiful dedicated office, with 4 full time office staff employees to assist you will all your staffing needs.  24/7 service, and over 32 years of experience under its belt.

To this day, Barb’s personal high standards, character, morals and values permeate every fiber of AOC – and the way it does business. The company refuses to compromise on the quality of the service it provides. Therefore, those whom AOC employs, must be top notch.

Thank you for making AOC the best temporary/permanent staffing company in Colorado

…since 1983.
