Your redesign…set the industry standard

“I believe that your redesign of the Zoll software application set the industry standard (I am not alone in this opinion) and our big picture goal is to set a new standard.” Robert Pabst, EMS Field Solutions Integration Manager Intermedix

He is…an outstanding talent when it comes to designing elegantly usable web pages

After knowing Dr. Mandel for over fifteen years, and working closely with him for the past three years now, words simply fail me in giving Dr. Mandel the recommendation he deserves, but I’ll try anyway. He is not only an outstanding talent when it comes to designing elegantly usable web pages, but he is oneContinue Reading

…in the top 5% of web design folks I have used in the past 15 years

“Theo Mandel designed two high visibility commercial web sites for Blackboard – one is a user-oriented site for parents and students at universities and colleges, the other is the administrative site to manage the public site. During the past months, I have been impressed with Theo’s ability to deliver very high quality work with aContinue Reading

Customers loved the new look and feel

“Theo revamped the user interface for ZOLL Data Systems’ mobile electronic patient care product. Customers loved the new look and feel. Theo worked very well with our team and not only improved the product but imparted valuable knowledge to the team during the project.” David Cohen, Founder Pinpoint Technologies (now Zoll Medical Corporation)

Theo’s reputation and credentials were outstanding

“In defining a new product, it was clear that we needed to understand the customer and user needs as well as we could. We searched for the right caliber of professional who could both establish a rapport with all levels at the customer company and also prepare an exceptional design for a user interface. OurContinue Reading

Dr. Mandel suggested solutions that greatly improved the site

“We had been working on Bombardier Skyjet’s website redesign for several months when I decided to attend a seminar in Washington DC featuring Dr. Mandel. His presentation on best practices in website design and usability convinced me that it was time for a set of unbiased eyes to review the website before we launched it.Continue Reading

Sincere joy and pleasure to work with

“I want to take a few moments to thank you for your wonderful guidance and contribution to our recent software program. Before you came aboard and joined our developmental team, we were floundering with a well-conceived idea but one that was poorly designed, aesthetically deficient, and structurally inadequate. Through your diligent efforts and direction, ourContinue Reading

“Steady hand” in focusing on the core principles

“Dr. Theo Mandel played a very significant role in guiding the development of our division-wide HR Intranet, designed to bring pertinent HR information directly to the desktops of 6000 employees and managers in the most user-friendly form possible. Theo’s expertise in human factors and usability had a profound impact on the very successful design ofContinue Reading

We are delighted!” Jeffrey Horn, Principal, Towers Perrin Founder, The Business Development Group

Attention to detail

“As one of the leading medical information networks on the Web, we chose Theo Mandel to set the tone for’s site. The attention to detail, professionalism and personal consultation with Mr. Mandel and his staff has paid big dividends for us.” Paul Hershey, Vice President of Marketing

Working with Theo is always a learning experience

“The importance of usability in systems design cannot be over emphasized. Systems are inherently expensive investments. A system with poor human factors is a constant drain on productivity, morale and budget. Theo Mandel has been instrumental in helping DTE to design systems that humans can use productively and without expensive training. Working with Theo isContinue Reading

Theo takes time to explain reasons behind approach

“Theo takes the time to explain the reasoning behind a certain approach. At the end of a project, you feel comfortable with the decisions that were made and can make your own usability decisions in future projects based on your experience working with Theo.” Andy Greff, Senior Manager Motive Communications

A great contribution and partner for any user interface work to come

“I saw the results of Theo’s work when we were both at IBM working to derive the best UI principles to drive common user interface standards — before there were those, before users could reliably transfer their learning from one application to another. He codified the state of this early landscape in his book “TheContinue Reading
