"I met Ryan Amundson 2 yrs ago when my mom hired him to do a home inspection. Since then, my daughter, my son, and myself have all hired him to do home inspections on our new home purchases. He is AWESOME! Very professional! He is very thorough but still personal. Even when I interrupt him with my many questions, he is always willing to take time to explain things, show me items, and give me advise. His reports are easy to understand and always accompanied by great photos of any issues. I would highly recommend A-MAX and Ryan Amundson. You wonÃ¢Â Â t be sorry!"
