"Dan was the first product designer I'd ever used, and he made the process much more approachable and easier than I had anticipated. He took the time to explain to me not only the process of product design, but also the general timeline and chronology of taking an "idea" and bringing it to fruition, and possibly to market. His work was done with great care to accurately represent my idea. He listened to what I wanted the product to be used for and kept that in mind while designing, yet still gave input, based on his prior experiences, as to what would be the most beneficial, cost-effective route. The end result was a design that didn't even need to be revisited before I was able to make a prototype."

"In early 2010, I had the pleasure to meet Dan Tangtow. I say the "pleasure", as Dan was able to help me reach my goals to develop a new fishing float with great precision. The requirements to meet the product's design were carefully worked on over a course of six months. After three prototypes Dan successfully met all my requirements and the final product was released for testing.

Dan's ability to listen to my needs and make recommendations as required helped in the final design to our product. His commitment and professionalism to help me reach my needs has established a strong partnership between us. As I continue to work on other projects, Dan will continue to be my designer.

I highly recommend Dan Tangtow as the preferred designer to any individual and/or company seeking to receive the personal touch."

"I have had the pleasure of working with Dan Tagtow over the past eight years on a continuous basis. I have a small consulting practice that is heavily involved in new product development, Dan has been extremely helpful assisting me with the development of components for new products, we have just completed a one million dollar project to design and develop a high performance Lawn and Garden Sprayer. We worked as a team, I with the original concepts and Dan with the engineering design, which turns ideas into functioning components. We have been very successful on this and many other products over the years.

I am extremely impressed with Dan's engineering design capabilities, not once have we had to go back and make changes to a component, once the design was complete and the component manufactured, it worked as conceived the first time every time. I will continue to work with Dan as required and have no hesitation recommending Dan for any engineering design concept that may be required. I would be happy to speak to anyone in this regard and wish Dan much success with his new venture."
