The right talent at the right moment

We provide expert consultants that help enterprise businesses meet opportunities as they arise.


Before Ellen and Shanaz founded Derflan in 2007, they sat exactly where their clients sit: managing large projects with complex and changing needs for enterprise companies. They hired consultants, worked with consultants, and saw an opportunity to improve those relationships and their outcomes.

As a result, Derflan is more than the sum of its individual parts. Our consultants form a collaborative network of experts, supported by a staff with enterprise business experience. We focus on our clients’ long term success and pride ourselves on being strategic thinkers who can also roll-up our sleeves and get the job done.

What’s in a name?

“Derflan” is a tribute to our founders’ personal experience as first generation Americans. Ellen’s father, George, was born in Derfle, a tiny village in the Czech Republic. The villagers were affectionately referred to as “Derflans”—a term that followed George all the way to the U.S. and became his lifelong nickname. Ellen and Shanaz decided to carry on the name as a testament to the vision, courage and hard work of their parents—all immigrants to the U.S.—who paved the way for them to build this company.
