My design background is rooted in my personal life.

-I am a well accomplished furniture and cabinet maker. I have a fully equipped workshop and use it as often as I can.

-I am also a wood turner. I produce unique hand turned wood ornaments along with a variety of covered bowls and hollow vessels.

-For 35+ years I have had a deep interest in photography and am accomplished in the 35mm, 4x5 and digital arenas.

Recommendations For David

“I was involved with David over the course of many years. David worked on many of the advanced development projects being done in my department. I along with my employees worked with David developing products and the related processes. His knowledge of airflow, fluidics, materials, and processes was an asset to all of our projects. He not only delivered manufacturable designs but also designs that were extremely manufacturing friendly from a tooling, equipment, investment, and process control standpoint. I can highly recommend David as a designer who will get the job done but will also have done the bulk of the manufacturing engineering as well.” March 19, 2010

Kurt Hertzog, Dept. Mgr. - Advanced Process Development, Delphiworked with David A at Delphi Automotive Systems


"Dave can take pride in the fact that he always did the job correctly and quickly.  I have used many models created by Dave to run computer simulations and never did I find issues with the models (not something that can be universally said for all Designers).

  Dave did not just draw the part; he typically was responsible for generation of the entire design concept.  He has a very unique way of understanding the part design function and it’s interaction with the manufacturing process.  For example, Dave was given the task of designing composite intake manifolds.  These are extremely complex parts and they require a person with a very unique, geometric mind in order to visualize and create their shapes.  For most of our high profile projects, Dave was given the lead role in generating these part designs.  He handled this responsibility effectively and professionally and was a recognized expert in this field."

Gary De Angelis, Sr. Plastics Engineer, Delphi

worked with David A at Delphi Automotive Systems


“Dave is top of his field. He has a non-stop drive to improve the products that he designs as well as the tools that he uses to design them. Dave led the design group's continuous improvement of CAD tools and developed new approaches that became standards for the rest of the team. Dave is highly inventive and his innovations advanced the companies air and fuel products. Dave led the design of the highest production volume products produced by the Integrated Air Fuel Module group.” March 22, 2010

Keith Confer, Engineering Manager - Forward Systems, Delphi

managed David A indirectly at Delphi Automotive Systems


“David worked at Delphi as a Senior Product Designer. His contribution to the organization was quite significant, as he offered a superior technical and creative approach, resulting in much of his work driving the technical direction for the product lines. David's creative and technical skills have both breadth and depth, which allows him to deliver every time!” March 21, 2010

Top qualities: Great Results, Expert, Creative

James Zizelmanhired David A as a Product Designer in 1987


“Hands down the best UGNX designer I have worked with at Delphi.” March 18, 2010

Ahmet Becene PhD., Staff Research Engineer, Delphiworked with David A at Delphi Automotive Systems


“Dave and I worked together to migrate a Computation Fluid Dynamics application from a mainframe to a desktop environment. Dave was the voice of the end user and worked with other designers and engineers to ensure our migration expanded the overall usability. Dave brings years of in-depth experience designing and developing plastic & metal component parts.” March 22, 2010

Veera Madhure, Senior Engineering Project Manager, General Motors / Delphiworked with David A at Delphi Automotive Systems


“David exhibited very strong capability in the use of UG, has strong mechanical aptitude and is also familiar with airflow (manifold) optimization. He is intensely interested in his profession, taking initiative to continuously improve and has a good work ethic. I had the pleasure to work along side Dave for some years and was always impressed with his work. Don Witzel 585.278.0748” March 24, 2010
