Access the Signature Methods We Use With Our Clients

We’ve poured all of our collective experience, wisdom, expertise, and processes into this program.

The methods and frameworks we teach are the same ones we use in real life, with our clients. They have been turned into a course and interactive group format that’s easily digestible yet effective.

The aim is to give you the results you need for a fraction of the cost of hiring an employee, or one or both of us 1:1 (minimum 6-figure price tag).

We recognize the need for savings even at larger organizations.

Why an online program? Why not work together 1:1?

Having spent the past several years growing our respective businesses—on top of 12+ years in corporate each—we both have waiting lists for new one-on-one clients through spring 2023.

But we have more value to give the life science community and want to help as many organizations as possible!

We have personally invested in group programs ourselves, and they work. So we worked hard to put all our knowledge and systems into a group program made for life science organizations.

This format is ideal for busy leaders located anywhere in the world. All you need is a device, an internet connection, and the willingness to implement the strategies you gain. This allows companies to receive customized help, for a fraction of the cost of working with one or both of us one-on-one or as a project.

I have had the pleasure of knowing Erica for many years and I have always been impressed by the breadth of contacts she and Sosna + Co have, as well as their deep subject matter expertise.

As a CEO, having a team you can trust that is truly competent and dialed-in is invaluable.

And she's also really personable and smart—a pleasure to work with."
