    Ruth has been taking care of my small business & personal accounting needs since 2017. She is helpful, responsive, trustworthy, honest, and effective. I couldn't be more thankful for the help, knowledge, & direction she has provided me with over the years. With that being said, I recommend Cornerstone Tax & Accounting for any of your accounting needs!

    This is our second year working with Ruth. Never had a bad experience yet!

    This business should be receiving negative stars. We were a new client. We sat there while she rushed through our taxes not asking questions. She clearly did not understand the meaning of customer service nor did she care if she had our business. Had to go back three times due to wrong information typed into our taxes.
