About Us

Our Founders

Mark Miller and Julie Sager Miller co-founded Advantage Trust Company in 1997.  Their vision was simple:  to be a trusted advisor for their clients in the most important family and financial decisions those clients make.  Over the years, Mark and Julie built meaningful and lasting relationships with families that have continued down multiple generations.  While Mark and Julie have transitioned out of the day-to-day operations of the company, their leadership has provided their successors with the tools to continue these existing client relationships while also building new ones.  Mark and Julie continue to be active participants in the success of Advantage Trust Company.  Mark is a member of our Board of Directors and Trust Committee and Julie is a member of our Board of Directors, Trust Committee, and Investment Committee.
