About

With over 25 years in the IT industry starting with a solid foundation in sales and customer facing roles, I’ve had the honor and good fortune of working with and for some of the best companies, partners, and customers in the world. As a recognized leader in cyber operations, I have received accolades from customers and partners including the FBI and US Air Force; Travelers, Beazley, Chubb, and Tokio Marine cyber insurance providers; Mullen Coughlin, Lewis Brisbois Bisgaard & Smith, and Constangy Brooks Smith & Prophete law firms. Highlights of my career include the training of AI and machine learning models to achieve greater than 99.9% accuracy in detecting and preventing malicious code from executing on computers, detecting previously unknown attack campaigns on compromised websites that resulted in their takedown and remediation, while also being a part of four major mergers & acquisitions resulting in company valuations that were all over $500 million. One of the companies even reached unicorn status with an all-cash buyout agreement of over $1.4 billion. That company was also the fastest growing startup to hit the $1 billion mark.
