What Motivates Me?

10-year old David probably could not have guessed where I’d be now. I’ve made several pivots in deciding what I want in my career and I don’t imagine the changes will stop – from pre-med in college to software development in the healthcare sector as my first job out of school to engineering management now. Who knows where I’ll end up next? As long as I’m growing, I’ll be happy.


Learning to code has been an incredibly valuable skill that has opened doors for me in ways I wouldn’t have expected. Living in a digital world, it’s become more and more important understanding how things work.


Having a poor memory requires that I stay organized. My reason for loving strong organization schemes – whether it’s people organization, stuff organization, or data organization – is that it allows me to lean hard on the system and trust in its effectiveness.


Being a strong coder is only the start to developing robust applications. Taking these skills and applying them to guide a team of Developers creates a multiplying effect that produces productive results.


“If you want to walk fast, walk alone – if you want to walk far, walk with others “ A leader that can inspire others can get more done. I strive to model myself after leaders that have come before me and continue to build new leadership skills through various means of self improvement – books, training, and mentorship.

Winter Sports


Park City, Vail, Breckenridge, Whistler, Lake Tahoe, Killington are some of my favorite resorts to visit. I hope to be able to ski and ride in Europe and Japan at some point as well.

Summer Sports


Avid sailor since I was 10 years old. I sail all types of small boats – Lasers, Sunfishes, 420s, Rhodes 19s, Sonars, and even Windsurfs. It’s my dream to sail a catamaran on the open sea someday.


Passion for capturing the moment in all settings

Landscapes, portaits, candids, engagements, weddings, babies…I do it all!
