“For the past 2 years I have had the pleasure of working with Colin McMahon on designing and maintaining the primary website that is used for my work. I have nothing but great things to say about him and my experiences while working with him. He is always ready, willing and able to help me out, gives me great advise when I’m having troubles seeing the big picture and need some direction and is never further than a phone call away when I have a question and/or concern. When I was looking for a website host and some guidance on setting up my website I was totally lost and had no idea what I was doing. Colin helped me out so much and put my mind at ease with his extensive knowledge and professionalism and although I was lost I followed his lead and have not regretted once! He is an all-around good guy and I really feel that he has my best interest at heart. I would highly recommend him to anyone that is looking for a top notch web designer/consultant. Thank you Colin for everything you have done and continue to do for me and my business!”

“The McMahon Group has been amazing for our needs. We came in with a website that was designed and developed overseas, and the coding and structure was a mess. Colin and Mike have been able to improve it step by step and turn it into an excellent website. They have been responsive, communicative and always exceed expectations. I thoroughly enjoy working them and would highly recommend them to anyone with computer needs!”

“Colin gave me a foundation in improving my website’s SEO, strategic use of social media ads, and using that advertising to mine for information about my clients.”
