20+ Years. 90% Retention. that’s not luck.

I'm Cora Holland Haffner, and I've been designing high-performance operations for executives since 2005.

I began my career supporting former Delaware Governor Pete du Pont at Richards, Layton & Finger, where I managed confidential correspondence, coordinated multi-state and international travel, and collaborated with Executive Assistants at companies where he held board positions. That's where I learned that the best support is invisible: leaders should never have to think about whether something will get done.

Before that, I gained experience in crisis management at the Juvenile Diabetes Research Foundation, where I took over a flagship fundraiser eight weeks before the event following the Executive Director's sudden departure. We coordinated 50+ volunteers, secured sponsor relationships, and delivered a successful event. That's when I learned: when you organize complexity into clear roles and timelines, teams become a unified force—and what seemed impossible becomes inevitable.

I founded Simplicity in 2005 (became an LLC in 2018) because I saw a gap: executives needed strategic operational partners, not just assistants. Over the past 20 years, I've served leaders across venture capital, federal consulting, economic development, and nonprofit sectors. My 90% client retention rate exists because I solve problems before they become emergencies.

What I bring:

• Calendar architecture that protects strategic focus time

• Event execution with zero cost overruns (from board dinners to corporate conferences, with budgets from $5k to $90K)

• Technology implementation that reclaims hours weekly per client

• EA-to-EA relationships that get things done faster

• 20 years of discretion, white-glove service, and anticipatory problem-solving

I live in Wilmington, Delaware, with my husband and son.
