Rick Stamm


Rick Stamm founded The TEAM Approach, inc. in 1986. Rick began his career in the field of Vocational Rehabilitation and has always believed that work is central to a person’s well-being. Before he launched The TEAM Approach, Rick developed and led a non-profit organization called Gateway Placement Institute, dedicated to helping people with disabilities find competitive employment opportunities. He also was a pilot and group training office in the Air National Guard, retiring after 20 years of service.

Rick founded The TEAM Approach on a simple belief – teamwork is the key to service excellence, innovation, and increased productivity in any kind of business.

Rick developed his first DiSC Certification class in 1990 before the internet existed. These first classes were delivered via correspondence course and conference call technology. Over the years Rick has certified hundreds of learning professionals, HR leaders and consultants in the DiSC model.

Rick is a graduate of Albright College (BS – Math) and Penn State University (Master of Community Psychology).

Adam Stamm

Marketing Manager

After spending 7-years working in various Advertising and Marketing positions, Adam decided to leave his corporate job and join the family business.

While in advertising, Adam worked with household name brands (Hyundai/Kia, State Farm, Walgreens, Pepsi, and Clorox) and managed their various advertising campaigns. He was fascinated with how brands were able to maintain our attention and hoped to one day use the skills he developed to promote ideas or projects that would change lives rather than sell a product. For that reason, Adam was grateful for the opportunity to join the family business.

Adam has a passion for connecting with others and solving problems. He graduated from Albright College with a B.S. in Communications and English Literature.

In 2022, Adam was elected to the position of Vice President of Technology for the Greater Philadelphia Chapter of the Association of Talent Development.
