What Members Say

Leff, Ilene So wonderful to be among like-minded colleagues for learning, improving our practices, getting to know one another and having fun.

Ilene Leff

McKinsey alum

As a veteran of four Top Tier events, I can say that Will and Umbrex always bring relevant and timely topics for building a high quality consulting practice.

Geoff Wilson

McKinsey alum

Top Tier is a "must go to" event - a unique combination of networking, learning, reflecting and just plain good fun! I leave with renewed personal and professional relationships, new ideas to run my practice and new content for my clients.

MaryKate Scott

McKinsey alum

I learned enough in two of the sessions to pay for the opportunity cost of the event several times over.

Jamie Campbell

McKinsey alum

It's great to meet with peers and to expand your horizon. Time well spent.

Joachim Fischer

McKinsey alum

Absolutely fantastic professional development—just what I was missing as an independent!

Eli Diament

McKinsey alum

Umbrex provides a community of like-minded independent consultants who want to make an impact not only with their clients, but also within themselves and their communities.

Mark Gomez

Bain alum

Umbrex is a unique resource, with extraordinary value for consultants and clients. I talk to (and work with) a lot of consultants, consulting networks and, of course, clients. While most consulting networks are a loose amalgamation of firms or consultants under a common banner, Umbrex is something quite different—a vetted community.

David A. Fields

The Umbrex community is vibrant and supportive, events are top-notch, and the content is just superior.
