I met Sonja with Strate Accounting when I was in the middle of a huge mess with another accounting firm. Sonja took control of my accounting including my payroll, and had it all corrected and back on track.
With our business operating over 30 years now, we have had a few experiences with different firms and Strate is the perfect mix between professional and personal.
