Meet Sean Diller, an Associate on our Resolutions Team who helps businesses navigate IRS challenges and maintain critical funding relationships. Sean has been with Tax Guard since January of 2025 and works with businesses to resolve liabilities and keep operations moving forward. 

A few fun facts:

• Loves gardening, especially finding hardy perennials that can survive Colorado’s tough climate
• Previously taught 7th-grade math and science in New Orleans
• Used to have recurring nightmares about alligators (a Louisiana souvenir!)
• Has a soft spot for lilacs

Sean’s advice for small business owners? Set yourself up for success with the IRS — know your filing and deposit requirements and keep access to your EFTPS account handy.

What motivates him every day is knowing these challenges have solutions and helping businesses come out stronger on the other side.

We’re excited to have you on the team, Sean!
