Director of Product Management at DoorDash

I worked very closely with Dennis at Truss when I was VP of Product and he led the Design and UX team. Dennis is an incredible teammate who brings strong energy and great ideas to the product design process. He has a knack for taking even the most complicated user interactions, breaking them down, and reflecting them back as a tight and simple flow. He has a terrific aesthetic sense and iterates on concepts quickly with the team. I wouldn’t hesitate working with him in the future.

Having worked with Dennis for 5 years, in various capacities (co-worker, paid consultant, and my advisor) I can honestly say that I've never worked with a man that balances creativity with project execution, so seamlessly. Dennis is a consummate team player, who will roll up his sleeves and work tirelessly to delight customers that touch his UI/UX design. I'd recommend Dennis without - hesitation or reservation - to anyone.

Dennis has been a personal mentor to me in my path to learn UX and Web Design. Working with him the past few years has been an absolute joy. He is an incredibly hard worker, and goes above and beyond to deliver amazing work and crush deadlines. He's truly able to think outside the box and create memorable and unique experiences for the web. I had the pleasure of working on several UX projects with Dennis and I learned a ton about design process and human-centered design from him. Dennis has been a great teacher, co-worker and friend, and I wouldn't hesitate to work with him in the future.

Dennis has been a personal mentor to me the past two years and I have had the privilege of working side by side with him. He is very reliable, hard working creative and will step in and help and member of the team whenever possible. dennis is very intelligent and has gone out of his way countless times to teach me many valuable tools I will throughout my career.
