Working with Juan is always a pleasure.  First of all, he really knows his stuff when it comes to designing foodservice equipment.  Juan is a hard-worker. And most importantly, his number one priority is always to make the customer happy.  That is why I hired Juan to do many projects when I was Director of R&D at In-N-Out Burger.  It is why I will continue to utilize Juan's talents.

During the past few years, he has been assigned to several new projects, such as Beech Oven, Rotisserie, Rotating Duck oven and so on. He has played a critical role in making the project a success. He is very passionate at work. He always is willing to take over new challenges and responsibilities with strong problem-solving skill.


Juan has excellent interpersonal skills and is professional and respectful in our organization. His professional expertise has helped Jade engineering to be more efficient and stronger and is a valuable asset to our company. I am confident that he will make a huge difference as an engineer in your company.

"I had the pleasure of working with Juan Martinez for over 5 years. You can't ask for a more honest, dedicated, knowledgeable and professional person working for and with you. With a high level of expertise in his field, he also has excellent communication skills to relay what it is that he does best, and what he can do to optimally market your business. As a colleague, Juan is incredibly generous with his time and expertise, which includes everything from his lots of years of management experience to an expert-level knowledge of Engineering Design. Beyond that, his humor and good nature make tough deadlines much easier on his team. For the past five years, I've benefited from his creative problem-solving, tireless work ethic, and willingness to do whatever it takes to create a product that will translate the customer's vision into reality.

It is my pleasure to recommend Nexus Engineering Services (NES) and Juan Martinez as I have nothing but positive comments about their integrity, attention to detail, and sense of urgency with my experiences.  I know and worked with Juan prior to NES and appreciated his professionalism and genuine concern about my time and delivering quality work to meet my deadlines.  I have the confidence that when working with NES I am receiving a fair priced, quality product and would recommend and will use them in the future.
