Susan Casaccio Healing Massage In Surprise

The Sigma Sites team has been wonderful to work with over the last couple of years. I began with construction of a brand new site and have used them to host and manage my site as well. My questions are always answered promptly and the team is attentive. I'd recommend Sigma Sites to anyone.

Les rocks... We're developers ourselves so really appreciate working with a truly professional guy who gets the job done quickly while keeping you up to date all the way along. Flawless execution and top quality code. We will be using Les often.

Finding and entrusting the right partner to promote and market your enterprise is akin to child care. There is nothing more important. Your livelihood and that of your family hangs on the success and profitability of your business and therefore you have to choose wisely. Before selecting Sigma Sites I was interviewing and considering other companies who claimed to do what Leslie Nielsen does. Each time I had a question, they would refer me to a brochure, direct me to a website or give me the number of some anonymous, faceless individual; not so Leslie. He has the answers; he has been doing this work for years; it’s in his blood; it’s what he loves to do. Not only is his methodology proficient, Leslie is a consummate professional who will work with you on a budget that fits your pocket. There are no contracts. Before you know it you will forget that Leslie is a contractor and instead will discover that he becomes a confident; a silent partner who wants you to do well. In his words, “your success is what I love and why I do what I do.” Partnering with Sigma Sites is a smart move towards shared prosperity and accomplishment.

Co-Founder, Walk The Ridge

Les worked for me, in crafting the website and its functionality for the growing movement called WALK THE RIDGE. Not only was he knowledgeable, but in crafting some of the solution, he actually tapped into a customized programming tool that he designed for efficiency.
Smart, talented, and very dedicated to communicating regularly. Overdelivered on service and results.
Strong recommendation from me.
