Mark’s venture capital experience began in 1981, when he helped launch a biomass venture backed by General Electric’s venture capital group (now Canaan Partners) using technology developed at the University of Pennsylvania.

He has served on 46 public and private company boards. Mark has also been responsible for TL’s participation in the Kauffman Fellows program and, with Anthony Chang, developing an effective network in Asia to assist TL portfolio companies source and sell products there.Recognizing long ago that the energy and utility industries were ripe for early-stage investing capable of generating venture-type returns, Mark established an affiliated private equity activity targeting those markets specifically.
