This profile is particularly effortless to write since Mark has been the most "eligible" bachelor I know since I became friends with him through my husband about 2 years ago. He let me take over his profile, so here's the breakdown, girls! First and foremost, Mark is smart, educated, and passionate about what he does. Top notch undergrad and MBA, and he was smart/scrappy enough to start and sell the first voice-over-IP company (before Skype) in the 1990s. You can't do much better than that. Which leads me to…Mark sits at the intersection of science and entrepreneurship, so he's got that nerd thing going on (without the poor communication skills that can usually accompany these guys) while simultaneously being a high-powered business guy (without the "douchebag" personality that can usually accompany these guys). It's a good combination.He's a sweetheart! I love hanging out with Mark because he's considerate and a good listener. Although out in Houston with his highly successful latest company, he somehow missed the arrogant jerk gene. He is thoughtful, generous, and loyal to his friends – just a kind soul.Every girl wants to know this, so I'll just throw it out there – yes, he's very attractive. Clean cut and nice build. Good presence. Most importantly, I've spent many hours talking to Mark about relationships and know he's got a healthy, positive attitude towards finding the "right one". I've observed him as a great friend, a great brother, and a great son. All told, I can't think of a better guy to get to know!
