Great CPA. Quite knowledgeable on his knowledge. I just moved my adult daughter account for him to work on. My own return is a bit more complex, I use a top ten accounting firm. In a few years when i reduce the complexity of my own return I will probably use Mr. Mroz. Mr. Mroz is quite up to date on the IRS code. read more

I just had a "free" consultation with Stan. He helped me understand the gift tax issue, and advised me how to handle it. Very helpful! read more

Cost me his fee 900.00 plus 3000.00in penalties!!! Total incompetence...

Stan was extremely helpful when I scheduled my first consultation with him. He showed me honesty and compassion and I am thankful he saw to it that I received the help I needed. He was very sweet and listened to my "story" patiently. When I left, he gave me a hug and helps me feel at ease. He is really great with people and helping them to feel valued and important! Thank you for helping me out Stan! read more

My 2016 taxes could have turned into a DISASTER if I had chosen to trust the wrong person to handle my confusing situation! I had three states to file plus federal taxes, a cross country move, W2's from 2 different states, stock sale and a closing of a 401k plan. Needless to say I was rather worried I would owe a huge sum of money. Stanley was referred to me by a co-worker that has trusted him with her business and personal finances for years. I made an appointment using the handy online form and quickly received a response from a friendly receptionist. ( I note friendly because most receptionists I've dealt with at various places in the valley are cold and unfriendly.) I was able to get the appointment time I requested. The location is easy to find using google maps and there is plenty of parking. Stanley explained his fees and the process as well as software they use for their tax services. Our taxes were completed and we arranged to pick them up. Signed where it was noted and we were off! He did a great job and found us some deductions we were not expecting. Everyone at the office we worked with was pleasant and quick to respond via phone and email. Thank you! We will be back again! read more

Stan was outstanding! I called late on Friday afternoon for a question I didn't want to wait till Monday for an answer. Stan took my call and was most knowledgeable and helpful and wouldn't take any money for a 10-15 minute call. I highly recommend Stan Mroz. Sincerely Patrick Fairman read more

We were going to use Mr. Mroz to do our taxes for us. We are Canadian and wanted an American accountant to do our taxes for a US property we owned. We paid $215 dollars for a phone call which was suppose to give us a 30 minute credit if we did our taxes with him. Then I emailed and asked a question about a government website in regards to Transient Occupancy tax. He basically answered that I could look it up on the website and then gave the address to the website I already mentioned I was looking at. Then he sent a bill for $65. I said that I did not feel that was a fair charge and he could take it out of our credit because I was switching accountants. We then found an accounting firm who did all of our taxes for a $300 set price. Mr. Mroz has since sent a collection agency after us for the $65. read more
