Mallory Sone is a Manager in our Tax Department. She works with small business owners across multiple industries and with estates and trusts. Additionally, she finds ways to help self-employed entrepreneurs plan for and reduce their potential tax liabilities. Mallory also provides high net-worth individuals with tax and compliance preparation and assistance. She enjoys working with non-profits and believes that helping them with their accounting needs gives them more time to focus on bettering our local community.
