Our People

From the first day of the firm, we have believed in a people-first company; it is one of the main reasons we created Ascent. This belief translates to a relentless effort to help our people grow their careers, to support the welfare of the whole person not just the professional person, and to recognize that our people’s success defines the success of the firm.
