Editor-in-Chief at TechSpective
I have a passion for technology and gadgets and a desire to help others understand how technology can affect or improve their lives. I also love spending time with my wife, 7 kids, 3 dogs, 5 cats, a pot-bellied pig, and sulcata tortoise, and I like to think I enjoy reading and golf even though I never find time for either.
