Trofholz is my grandfather’s family name.

“It was Leon Trofholz’ vision and commitment that inspired me to build my own company based on his values. He encouraged me to aspire beyond limitations, regardless of how challenging a situation might seem. He often counseled, ‘If you want to be more, you can. Just be prepared to do more to make it happen.’ My grandfather’s principles guide us as we contribute to every client’s success.”
