Dan's encouragement and enthusiasm has played a substantial role in the development of the engineer that I am today. He was my guide while I was starting to learn about machine learning and graph analytical techniques. He was instrumental in my development as a teacher -- something I find important as we try to democratize access to machine learning. Dan demonstrated how to make complex topics like computer vision and driverless RC cars approachable. He then helped me do the same with a course on graph-based machine learning. Dan is known for his approachable and welcoming demeanour. That would give me the extra bit of confidence to try new things and grow.

Just like his book, when speaking with Dan you learn something new every several sentences. His technical acumen is unrivaled. What's not conveyed in his writing is how incredibly thoughtful and personable Dan is to be around. Anytime I was in town, Dan made time to take me out to lunch and make sure I was doing well.

In technology you rarely get a chance to work with a person that is as personable as they are technically proficient. Dan is one of those rare people and it is an absolute pleasure to work with him. Dan has led and successfully delivered very strategic pre-sales and post-sales consulting engagements for one of my top healthcare clients (a top 5 payer and health services company). I am 100% comfortable with Dan's solution identification and development skills, his presentation skills, and his excellent client relationship management.

Dan is one of the few people I trust to interact with clients on his own without involving a sales / relationship manager. He cares deeply about his clients, company (integrated account team) and their mutual success. Several key wins have happened, or opportunities have been generated, due to Dan's natural curiosity, credibility and trust he has built in understanding client strategies, goals, pains and developing solutions to help achieve them.

Dan is an "A-list" IT consulting talent and even better person. He goes the extra mile to mitigate risk (both technical and process) and ensure success, positive results and satisfaction. In return, I go the extra mile for him when he asks because he's earned it.

Highly knowledgeable in his specialized areas, and eager to share that knowledge through training, documentation, and informal conversations. Always quick to respond to questions and thorough in answering them. He is definitely committed to recommending the best possible design, but also able to compromise when business needs trump best practices. One thing I definitely appreciated is that he is not only capable of cranking out large amounts of code, but also of commenting/documenting it thoroughly. All in all, working with Dan was a very positive and productive experience.

Dan and I have collaborated on projects at the University of Richmond and in the open source community for years. Dan is a NoSQL Database visionary. His Enterprise Architecture experience and thinking has helped me become a better Enterprise Architect. While Dan is a visionary he is also down to earth and a very effective trainer and technical mentor. Dan’s training approach helped my team go from novice to experienced XQuery developers quickly. I’m looking forward to a continued relationship with Dan and his staff.

Dan is very knowledgeable, a natural teacher and a published visionary. I worked with Dan on projects at NueMeta. Early on in the business model planning he was able to focus the team on solutions and capabilities of the technology that would solve the major pain points we had identified.

Dan is one of the most intelligent and enjoyable people I have worked with in the past 5 years. His depth of knowledge in data architecture is astounding, particularly in meta data, XML and business intelligence. He always brings a fresh enthusiasm to his work, and blends his experience with a broad understanding of industry standards and trends. While primarily a data architect, he is constantly looking for ways to apply new technologies, like Web Services or metadata registries, to his solutions. And he is an excellent teacher, capable of helping others understand new concepts and apply them effectively. It would be an honor to work with him again in the future.

I had the pleasure of working with Dan at Thrivent Financial on the PACE program. The original project I was to work on was put on hold and so I had the opportunity to work with Dan on a Metadata Registry he was creating with XForms and XQuery. I had not worked with those technologies before and he spent a lot of time with me training me. He was an extremely good mentor and very patient with me as I learned more. Dan's knowledge of metadata, xml, OLAP cubes, and services is extremely impressive. He is one of the most knowledgeable architects I've ever had the opportunity to work with in my career. I would highly recommend him! I hope I have the opportunity to work with him again in the future!

Dan's breadth and depth of knowledge around Business Intelligence Data Structures and Systems is impressive. He is well studied in this area and welcomes the opportunity to teach others.

At Integrity Solutions, Dan was a visionary, building the company from the group of 7 co-founders to over 70 people.

Steve Kenny¶

August 16, 2008
Pete reported directly to Dan

Dan was the guiding force behind what retrospectively was a technically totally unique and trend-setting consultancy. His infectious deep belief in the merit of Object-Orientation as the basis for providing main-stream, mission-critical business solutions better and faster than any other organization around at the time was key in helping us establish a real foot-hold in the Twin Cities. He combined solid technical roots with a real ability to communicate and persuade. Many of today's common-place technologies, development practices, and team organizational methodologies were a natural part of his future-looking, Innovative, and home-brewed skill set.

Jack Nutting¶

CTO at Shortcut Sweden
January 13, 2009
Dan was senior to Jack but didn't manage Jack directly

At Integrity Solutions, I worked among the best and brightest minds I've ever worked with, and Dan was integral in building that team. His broad knowledge base and clear technical vision gave the company a clear direction forward and served as a set of selection criteria for potential recruits during a period of major growth; During my 3 years there we went from under 10 people to approximately 50. Some of us used to joke that Dan would hire anybody who came into his office, but the flip-side of the joke was that Dan seemed to truly have a knack for pre-selecting people who would do a great job for the company; the slouches never made it to his office!

Loren Cahlander¶

Digital Transformation, Data Architecture, Big data, NoSQL, Analytics & Cloud Computing
November 22, 2008

Dan has a greater capacity for sharing his vision and enthusiasm for technology than anyone I've ever known. It was his lecture before my object-oriented programming course in college that sealed the deal on my career in tech, and as my boss and mentor in my first job after college, he provided encouragement and direction as I first began exploring ways of solving technical problems. Any success I've had in my career can be attributed largely to the experiences I had working with him and the other outstandingly smart people at Integrity Solutions, and I'll always be grateful for that opportunity.

Mitch Berg¶

Technical Writer and UX Design
February 7, 2007

Working in the same room as Dan was like riding in a Turbo Carrera with no brakes; you never knew where you were going to end up, but it was going to be an interesting trip. Dan is a visionary, the kind of guy every organization or team needs to put a goal, one worth shooting for, out in front of everyone else. A genuinely inspiring guy to work for.

Boss Logic¶

I left NeXT to take a "leave of absense" to lead one of their key software developers. I worked with Phil Town and got my first tast of running a small startup company. I worked with Mark Pelto when he managed the NeXT computers for the NSP Legal Department.

Ralph Foy¶

Sr Manager Software Engineering
October 29, 2008
Ralph worked with Dan but they were at different companies

Dan left mighty big shoes to fill when I started at NeXT. The company he founded was a valuable partner for both NeXT and a company I later worked with, Gage. Dan has the gift of deep technical insight into issues. At a time when it seemed that quick-and-dirty, superficial "solutions" were the fashion, he was a steadfast proponent of quality design--solutions with integrity, to be true to the name of the company he founded.

ETA Systems¶

I left Bell Labs to get more experience managing people. When I was just 26 I was managing a team of 14 people on the ETA Software Engineering Tools team.

Dan was a great SME (subject matter expert) for me to consult about documentation issues. I was a tech writer in the ETA System V group, writing system administration docs, and he was always good for getting the information I needed. I value good knowledgeable sources when I find them. He was always one of the good ones.

Jason Taylor¶

September 1, 2008

Dan was an outstanding member of the Thrivent architecture team, focused on the re-alignment of a project to match the businesses needs.

Dan inspires people. When we were physics majors together in college, he inspired the whole campus to adopt Ultimate (Frisbee), for which he is remembered to this day. Over the years, his bold career moves into new companies and emerging technologies have been an inspiration to me in my own career. A conversation with Dan invariably leaves you feeling your eyes have been opened to something new, exciting, and promising.
