Favio is responsive, prompt, and will address all your concerns. He was recommended to us by a family member and WOW were we amazed by his prompt service. We were worried that we were going to miss the tax deadline; however, after submitting our paperwork to the portal, Favio completed our tax docs in a matter of hours! Great customer service, affordable fees, will definitely file with his company moving forward!!

I am beyond grateful that my coworker/friend referred me to ArrietaCPA to do my taxes after having a bad experience with my former tax preparer. Favio was quick to respond, professional, accomodating, patient, and exceeded my expectations which I so appreciated since tax season is the most stressful time for everyone. Even though I'm sure he has a lot of clients, he made me feel like a VIP client. Couldn't have asked for a better CPA than him! Highly recommend his services and I definitely will be referring family and friends to this business as well. Thank you, Favio!

I can't say enough good things about Favio's services for both personal and business tax preparation. He's always quick to respond to anything and does a thorough job making sure everything is in order. Anytime someone asks me for a good CPA, I send them to ArrietaCPA.

I found Arrieta CPA on yelp a few months back and its been worth every penny! I was a bit skeptical on working with a cpa because of the nightmare stories I've heard, the folks at Arrieta CPA have erased that. I now have Favio do my bookkeeping, payroll and taxes for my business and I couldnt be happier. Its been a pleasure! Thank you.
