Darik Volpa

Founder & CEO

Darik Volpa's "professional" life began in healthcare with Stryker Corporation in 1994 where he successfully “climbed the ladder” for 10 years in various sales and marketing roles.

Taking the Leap

In May of 2003, Darik spread his entrepreneurial wings and started Understand.com- a company focused on creating highly visual animations that would solve the problem with doctor/patient communication.

Twelve years later, Understand has become a global medical education company with thousands of clients licensing content from around the world. Understand.com’s animations have been featured on The Doctors, Good Morning America, Dr. Phil and Bodies: The Exhibition. In 2010, Understand.com was recognized by Inc. Magazine as one of the fastest growing privately held companies in the U.S. ranking #1,354 in the Inc. 5,000.

What's Next?

In January 2014, Understand made a bold move to diversify outside of medical education and launched a new training concept called Rehearsal VRP.

Rehearsal has been embraced by global enterprises including Verizon, Allstate, Johnson & Johnson, Accenture, Honeywell, and CA Technologies. We now have over 100 well-known companies and 80,000+ users on the platform.

This is Big.

On January 1, 2015 Rehearsal was split away from Understand and is now a separate company focused on scaling operations, expanding our sales team, and capitalizing our first-to-market advantage in video role-play technology.

Darik remains CEO for both companies.
