Paul is married to Susan, his wife of more than 40 years. They have three wonderful grown sons, three amazing daughter-in-laws, and five (3-girls, 2-boys) adorable and perfect grandbabies. Although he travels extensively, both domestic and internationally, staying connected and engaged with family is his top priority. When time permits, Paul enjoys fly fishing, hand gun competitive shooting and backpacking/hiking/camping—almost anything to be outdoors.


He has a core commitment to serve others, in a local inner city school, empowering those with barriers of entry for employment, assisting various non-profits accomplish their missions and most of all, living out the “Golden Rule” in daily living. In his heart of hearts, his passion is serving the global health, nutrition and economic wellbeing of women and children, too often considered the most vulnerable and “least of these.” “It is my firm belief, that the success of any society rests on the wellbeing and legacy of the women and children. When generations of women and children are neglected and abused, the core foundation of the society is weakened and will never reach the full potential and social impact.”


The Bible says: What God the Father considers to be pure and genuine religion is this: to take care of orphans and widows in their suffering and to keep ones self from being corrupted by the world. “I have success and failures on both counts, but I thank God daily for His grace and mercy, and I remain committed to do everything to His glory.”

Our family also volunteers at a local foodbank often and each holiday when the family is gathered together we volunteer at Feeding America. Diana and her husband are proud that throughout the years their children have grown up with the “service to others” mantra and have given back themselves in so many ways. We believe you can never give too much care and compassion to those in need. In her spare time, Diana enjoys cooking, gardening and spending time outdoors with the family and their dog.


As the newest member of the Cypress team, Diana is excited to continue the level of excellence and service to the Cypress customers that they have come to expect.
