About Derrick
How They Work.
Derrick joined Black Diamond in 2023 with a specialized focus: helping couples and recent widows navigate financial planning during life transitions — especially when financial responsibility shifts after the loss of a spouse. His plans emphasize clarity, patience, and trusted guidance, so no one is rushed into decisions during what may already be the hardest chapter they've faced.
Before joining Black Diamond, Derrick spent nine years helping small businesses achieve their financial goals. He graduated from Pennsylvania State University with studies focused on leadership and communication, and holds the ChFC® and CLTC® designations.
Born and raised in Wilmington, Delaware, Derrick spends his free time at the golf course or walking the beach looking for shells.
