Greg Tillar, Chairman of the Board


Tillar, who also serves as CEO of NuGrowth Partners and NuGrowth Solutions, has over 25 years experience providing executive management and leadership to emerging domestic and international businesses. While his expertise lies in building and developing technology-based companies, he has also successfully led organizations in the advertising, non-profit, Internet, manufacturing and recreation sectors.

His extensive resume includes participating as an equity partner and management executive in the formation and launch of OneSource, a publishing and advertising company; nearly ten years as President and COO of Metatec Corporation, a publicly traded optical media manufacturer; and a position as Vice President of Sales for CompuServe, an international provider of business-to-business networking, where he provided strategic direction and leadership for the sales function of nearly 30 worldwide offices.

He is excited about what SIS has to offer and feels that as a team they are in a great position to help agencies increase efficiencies and profitability. “With our unique carrier side background,” he said, “we have the knowledge to continue to help the industry streamline information transfer and increase productivity.”

Alex Deak, President & CEO


Deak, who also serves on the board of Groundwork Group, providing information management and technology services to nonprofits, has held a variety of leadership roles in sales, large account management, business development, product management, ISO 9000 quality management, professional services, client services, and information technology.

Over the course of his extensive career, his leadership roles in technology-oriented software and services businesses have earned him recognition from a variety of sources, including a PCWeek cover article where he was recognized as one of the “New Breed” innovative, creative CIO’s, and a “Forty Under 40” award by Business First Magazine of Columbus, Ohio.

Deak said that he consistently receives feedback from customers who tell him that Partner XE is the best choice in agency management support; not only because of the system itself, but also because of the outstanding service they receive. “We know our customers and they know us. We have a close relationship with them and we appreciate what they mean to us,” he added.

Paul Fuller, Vice President of Sales


Fuller, who in addition to his role at SIS is a founding member of NuGrowth Solutions, has successfully led sales and operations for multiple firms across multiple industries, leading to millions of dollars in pipeline growth and revenue. He earned his M.A. in Communication from the University of Arizona, where he was a Fellowship scholar and served as an instructor in business and political communication practice and theory.

Responsible for developing and running a world-class sales organization that serves SIS clients and ensures growth, Fuller says that it is his firm belief that sales is about principled service and leadership. With SIS, he says, “It is exciting to be working with people who embrace these values every day: independent insurance agents… understanding our clients’ needs and helping them choose a solution that will work to benefit their business is what the SIS Sales team is about.”

Beth Wenning, Manager of Organizational Development


Wenning, who possesses innate relational and personnel development strengths, has broad expertise in account management, new business sales, operations, customer service, recruiting, training, event planning and promotion.

Prior to joining SIS, she performed as a top business development executive for NuGrowth Solutions. She has also served as a marketing manager and training consultant with Dale Carnegie Training of Ohio & Indiana.

Wenning feels that SIS is an extremely customer-focused organization, and says that, “Behind the scenes you will find dedicated professionals practicing good habits with a high set of values as we constantly explore and re-evaluate the best ways to serve our clients.”

Eric Weisgarber, Western Regional Sales Director


Weisgarber, who is also a NuGrowth Solutions partner, brings expertise in business development, CRM systems implementation and workflow automation to western regional sales for SIS.

Co-founder and co-owner of Allegiant Marketing Group, Inc., a full service direct mail business that he has led for a decade, and head of Weisgarber Investments, Inc., a business management entity that develops customer relationship management (CRM) systems for businesses from $0 to $50 million, he understands the challenges of business ownership and the necessity of efficient technical solutions to both day-to-day and long term problems.

Weisgarber said that while every independent insurance agency is unique, they all share a passion for serving their clients and their communities, adding that, “SIS’ Partner XE agency management system is the tool for independent agencies of all sizes to do just that.”
