"Don is not someone who's looking for a quick hit. He's patient, realistic, and comfortable with us taking the time necessary to build our company to scale."

Dave Hodess, Founder

"Don is a very supportive, proactive and seasoned board member with great insight into the issues and events taking place within our market.

"We've been very impressed with Don's business acumen. He's been a CEO before, and thinks about business issues intelligently. He's got a great grasp of the 'big picture,' has a good head for strategy and positioning, and is able to quickly distill key issues in a meeting to help keep us focused on what's important.

"Don's been a good personal coach to me. A CEO needs someone who's direct, yet helpful, and who they respect. I've found his counsel very valuable."

Derek Proudian, CEO

"Don is an experienced and accomplished entrepreneur, with a lot of business expertise to offer. I really value his advice."

Pete Bonee, Founder & CEO

"When we approached Vanguard initially, we had a technology that was absolutely brand new, targeted at a product category that didn't exist. I credit Don for being able to see beyond what existed to what could be. Not all VCs have that level of imagination and vision.

"Don has a keen business sense, a native ability to understand what will fly, and loads of operational experience to make it happen. It's a talent.

"Don is tremendously supportive of the companies he's involved in, interested and helpful. I could ask him for anything and he would do it in a snap."

Rob Shostak, Founder

"Don is smart, passionate about our business and very well-connected. He is a person of the highest integrity, comes to every board meeting and is there for us whenever we need him. He's a friend. He also works hard on our behalf - the investors in our recent financing rounds were a direct result of his efforts and connections."

Juan Mini, Founder
