Greg Brennan

President and CEO

Greg Brennan has been working with enterprise startups and spin outs since beginning his career in the microelectronics industry nearly 35 years ago. After working with several initial ventures, including privately held Vitarel Microelectronics, a spinout from AVX, and Scrantom Engineering, Greg joined Apex Microtechnology.

In 1995, Greg supported a management led exit of the company's founder, and five years later he drove the private equity purchase of Apex by Alerion Capital Group based in Scottsdale, Arizona. In 2007, Greg was instrumental to Apex's sale of Apex to Cirrus Logic Inc, headquartered in Austin, Texas. Immediately following the acquisition, Greg was named Vice President and General Manager, and an officer of the Corporation. When the company opted to sell the APP division in 2012, Greg was called upon to ensure its successful exit and completed the sale in July of 2012 re-establishing Apex Microtechnology as a stand-alone entity.

Outside his role of President and CEO, Greg serves as director on boards of several corporations in healthcare and consumer market segments. Greg's undergraduate education started in the BSEE program at Purdue University and was completed with a BS in business.
