Why Choose Us?

The difference between ATC and other trust companies is our understanding of "total wealth."  By addressing the client's 3 Dimensional Wealth, we can use the unique trust statues of South Dakota to perpetuate values in addition to valuables.  

ATC plays a fiduciary role as co-trustee, "delegated" trustee, or "directed" trustee working with one or more family members and/or family advisors (e.g., investment managers, CPAs , attorneys, insurance advisors, financial consultants, and planners, etc.) to fulfill our obligation as a trustee.

ATC seeks to find a way to ensure that all individuals involved in the administration and management of the trust complement each other and provide for the beneficiaries and heirs in consideration of their needs in the context of the personal interrelationships within the family.

Often corporate fiduciaries demand or eventually seek total control in carrying out the trustee functions, unlike ATC. ATC's objective is not for the individuals, advisors and/or co-trustees involved to lose control, but rather to gain more control and be able to execute their roles without being burdened by concerns over the trust administration functions.
Often wealthy families desire a trustee willing to "delegate" certain responsibilities such as investment management (i.e., delegated trustee) or to accept direction from an Investment Committee and/or Distribution Committee (i.e., directed trustee). ATC is able to efficiently accommodate these scenarios with experienced and knowledgeable administrators and state-of-the-art technology. 

If desired, ATC can also serve as "full" trustee, providing a family with an all-inclusive approach to trust administration.
