About Us

The ROI Group is focused on developing and implementing business strategies for companies that want to expand or market within the United States and Canada or Asia, as well as other markets .  We help create sustainable, profitable growth for our clients while achieving a substantial Return on Investment:  hence, the name of our group.  

What Sets Us Apart

The ROI Group is comprised of senior-level executives with hands-on, operational experience along with trusted, seasoned partners with specific industry and functional skills. After listening to your needs and concerns, we’ll develop recommendations based on a 360̊ analysis of your business. We work with you as a cohesive, focused team.


Unlike many consultancies that drop a thick business plan folder on your desk and walk away, The ROI Group creates and implements the plans authorized by our clients.  We also offer transitional planning to help your company manage its expanded business long term. This may include training your employees to handle some or all international functions and assuring you have the resources to maintain your growth trajectory. 

We believe transitional planning is one of the most important factors that differentiates us from other consultancies.  And it’s another way we deliver superior value to clients.

Warren Vollmar 


Warren’s background is in corporate, agency consulting, and new-to-the-world product environments where he gained extensive experience in marketing, change management and business management. 

He founded The R O I Group after leaving 3M where he worked in a corporate-level new product development department.  There he analyzed new-to-the-world product concepts to begin commercialization.  Each opportunity was treated as a start-up company and included R&D, manufacturing/partner coordination, channel development, sales and marketing and more.


He also was a key member of a 3M management team responsible for consolidating all industrial sales and marketing operations.  This required new internal and channel processes and constant, fast communications.  He created a single database housing information on 30,000 products, eliminating more than 100 stand-alone databases to produce a $5 million savings.  His extensive experience enables him to advise Chinese companies that need to adapt management of their companies to western processes. 

Warren received a Bachelor of Science degree from the University of Wisconsin-Milwaukee and has taught as an Adjunct Professor in the master degree program at the University of St. Thomas. He served as President of the U.S. – China Business Connection organization for seven years. He is Director Emeritus of Wingspan Life Resources and a volunteer on its New Business Development Committee; a member of the Clean Economy Network, American Association of Microbusinesses, Global Citizen, the International Biochar Initiative; and is an accredited member of the Public Relations Society of America.
