Alex Kozak

Alex Kozak
Vice President, Customer Success

Alex has spent his career working with many of the world’s largest organizations, both domestically and internationally, in effort to help them transform segments of their business around emerging technology. This experience has yielded a tenacious focus on value-driven services delivery and customer relationship management, the two primary areas of emphasis in his role at Iagnosis. Alex and his team support our customers during the initial implementation of our platform, and through an ongoing dialog around extending adoption and maximizing the related benefits to both the practice and patient community.

Outside of Iagnosis, Alex mostly enjoys time with his family, exploring a wide variety of musical tastes, playing guitar and nurturing a feeble attempt at an amateur dek hockey career. He has also made his mark on Pittsburgh pop culture as the creator of the “Yappin’ Yinzers” – a line of talking plush dolls that speak the local dialect, known as “Pittsburghese”.
