Jen has been doing our taxes for at least 15 years! Jen and her team are amazing. They are quick to answer questions and send out things throughout the year to help you prepare for the tax season. We drive 2 hours to have Jen do our taxes, if that gives you any idea how much we trust her accounting ability.

I was so pleased with the service I received from Jen, she was very attentive and patient while explaining what i needed to get my business back on track and what was needed to have accurate records. Prior to our meeting I was not successful in retrieving my EIN # obtained in 2021. One call with instructions from Jen and the information was sent to my email in the same hour, I am so please with Cornerstones Service,
