Client Reviews
“I highly recommend Ryan Sampson with Assertion CPA. I was using another CPA previously who missed thousands of dollars of deductions, which Ryan was able to catch and account for in this year's tax return. Ryan will take care of you [and] leave no stone unturned.”

“We came to Ryan for help with our taxes as our circumstances have changed over the last couple of years and the added complexity was beyond our understanding. Ryan was so great to work with. He was always available for questions and stepped us through everything so we could better understand the process…we are so grateful to have found him!”

“Ryan helped us with filing 2 business returns and a personal tax return. It was great working with Ryan and quite honestly, he has been a breath of fresh air! In an accountant we look for someone both knowledgeable and responsive. Ryan embodied both of these qualities. His process was also very smooth and efficient! We definitely recommend Ryan and will be requesting his services again next year!”
