Marx Realty announced telemedicine giant Teladoc Health has expanded and extended its lease at 10 Grand Central. The firm will more than double its footprint at the repositioned office tower, taking a total of 15,000 square feet in a 10-year deal as it relocates its corporate headquarters from Purchase, NY. Exiger, a cyber security and supply chain technology firm, will take 7,000 square feet in a new, seven-year lease at 10 Grand Central.

Teladoc was represented by Sean Lynch of JLL while Exiger was represented by Mitchell Konsker and Simon Landsmann of JLL. JLL’s Mitchell Konsker, Carlee Palmer, Simon Landmann, and Thomas Schwartz are leading a team handling leasing for Marx Realty.

“The Teladoc story is compelling in that the firm has chosen to abandon its suburban New York headquarters in favor of the spectacular office experience and one-seat commute we offer tenants at 10 Grand Central,” said Craig Deitelzweig, CEO of Marx Realty.
