"Jack is very supportive, a great listener, and is always there with advice. He is truly the best friend a CEO could have. I trust him as a confidant, and know that when I have issues to share he'll be there to help.

"Jack is available 24/7, and always willing to go out of his way to help in any way. I have four phone numbers so I can reach him any time, anywhere. That's real commitment.

"Just as we set out to raise our Series B round, the market started to decline. We were making traction, but not nearly as fast as anticipated. I sat down with Jack to seek his help, and within a couple of weeks had term sheets on the table. He really focused full-time on our project. He was the driving force behind our success in raising $80 million in record time in nearly impossible market conditions."

Alex Naqvi, Founder & CEO

"Jack quickly became a champion of our technology. He gets personally involved and excited by the possibilities for our business.

"Jack clearly led the way in identifying new, solid investors for our third round, which was quite oversubscribed. His enthusiasm, based on a full knowledge of the potential of the company, was key to our success in securing those funds.

"Jack is a person of integrity, graciousness and honesty, with a never-ending thirst for understanding new things. He pursues his interests and investments with a true passion."

Aram Mooradian, Founder

"As the Chairman of our Board, Jack brings extensive knowledge of the cardiac space, and incredible stewardship and guidance.

"Jack understands the nuances of this market segment, and quickly sees the potential of a new idea or technology."

Nancy Briefs, CEO
