“We are fortunate to have Mike serve in this leadership position on our Board,” said Host.  “He is well-known and respected in the community and has a firm commitment to upholding the interests of Trustmark and our shareholders.  Mike will do an exemplary job in guiding our Board as we continue to build our diverse financial services franchise.”

Michael Summerford commented, “I look forward to the opportunity to serve as Chairman of Trustmark and continuing to work with our Board to lead a strong regional banking organization committed to providing value for its customers, shareholders, communities and associates.  Trustmark is well-positioned for continued success, thanks in part to Dan Grafton’s solid leadership and wise counsel as Chairman.”

Daniel Grafton commented, “My time with Trustmark has been both professionally satisfying and stimulating.  The Board and bank leadership are highly engaged and among the best in the business, which gives me great confidence in the future success of Trustmark.   The election of Mike Summerford as Chairman is the right person for the right time.  I have served with Mike for the last ten years and found him to be an extremely bright, hardworking professional with excellent leadership acumen.  The Host/Summerford team ensures continuity of leadership that benefits our communities, associates, customers and shareholders.”
