Our Team

So many of our clients tell us they’ve been underwhelmed by other consultants they’ve worked with. They notice an immediate difference once they partner with us.

We do what we say we’ll do—and often more. We hold each other, and our clients, accountable. We are relentless when it comes to hitting your campaign goal.

Take a look at our biographies and you’ll notice the Winkler Group team is filled with the brightest fundraising minds—experts with an average 15 years of experience who have walked in your shoes as nonprofit executives, vice presidents of advancement, directors of development, and major gifts officers.

As your strategic partner, we’ll bring this collective wisdom, and also extra hands to lighten the load. We’ll confidently lead you every step of the way, and we’ll also get in the trenches with you. Your campaign is too important to handle any other way.
