“Thanks again for your diligence and attention to detail and quality on the Bike Shop. You’ve got a great crew. Please pass it on that the building looks great and the project is well received. When the opportunity presents itself, I have it in mind to get you involved in one of our projects, something contemporary, green and innovative with solar.”
Wm. Howard Wittausch,, UCSB Bike Shop
“From design to delivery, API handled all of the details and changes to our satisfaction. During the installation process, API’s staff could not have been more professional and courteous. We have been in our new office coming up on a year, and we couldn’t be happier with how everything turned out.”
Aaron J. Cisney, General Manager, Rancho Guadalupe, LLC
From beginning to end, API worked well with us to allow our dream of a much needed and cost effective facility to become a reality. From the original meetings, design work, answering our numerous question, through the actual build, we felt more like partners than customers. We recommend Mr. Martino and his team at API to you without reservation.”

Earlier this month, I required some maintenance on the trailer and call API for help. I was put in touch with Jim Arkinson, who handled the job. He turned around a price quote immediately. After making some additions to the original quote, I authorized the work. A crew was immediately dispatched and did an excellent and professional job. I am well satisfied with the result. I want to compliment API on it’s attention to customer service. Your entire staff, including the receptionist, work crew and especially Jim Arkinson, made me feel that API truly valued by business, even though mine was a small job relative to the work you usually do. Previously to starting my own business, I was vice president of marketing at a high technology company. As a result, I recognize that API’s focus on customer service is a direct result of the commitment of senior management to it’s customers. My compliments to you and your staff.
