Our Team

Chameleonic Mascot

REAL “Mac” McCoy

Mac was born to blend into our clientele’s company culture, as our employees do every day. We don’t want our client employees or management team to view us as an outsourced provider: We want them to view us as their Human Resources department, blending into their culture. Our on-site HR employees who work for Resource Alliance are actually given the client’s business cards, with phone numbers and e-mail addresses from clients’ corporate locations. Some have even been chosen as our clients’ Employee of the Year!

Dennis and his brother Andy Weyenberg started Resource Alliance in August 2001, when he noticed a trend in the Professional Employer Organization industry towards more flexibility and hands-on human resources services for small to medium-sized businesses. Resource Alliance was formed in order to create customized HR solutions for companies with HR departments needing additional support, and for companies needing to develop a cost-effective HR support structure. Mr. Weyenberg holds a Bachelor’s degree in Business Administration from the University of Wisconsin-Eau Claire.
