L. Thomas Heiser
President and CEO
Mr. Heiser joins Ridgetop Group with more than 35 years of experience in the electronics industry, having spent 30+ years at Hitachi in various executive roles. Most recently Mr. Heiser led Hitachi High Technologies Systems Products Division and business development group. He has led global sales, manufacturing, and business development initiatives inside of Hitachi.
- Bachelor of Science degree in Business and Economics from Rockford University, IL.
Accustomed to pioneering innovative electronic technology and establishing engineering milestones, Mr. Goodman’s comprehensive background encompasses low-noise instrumentation, design-for-test (DFT), fault simulation techniques, and design tool development at established firms such as Tektronix and Honeywell. This innovative mindset was integral to the development of the first DSP-based IF processing for spectral analyzers, of which he was a leading team member in its creation.
Mr. Goodman successfully steered engineering at Analogy Inc., working on electromechanical design simulation tools as Vice President until its IPO. This experience inspired him to Co-found and head Opmaxx Inc., a design-for-test IP firm that later merged with Credence Systems.
- Bachelor of Science degree in Electrical Engineering from California Polytechnic State University, San Luis Obispo.
- MBA from the University of Portland, Oregon.
