Blazek & Vetterling first opened its doors in 1991 with a small team.  Over the years we’ve grown the firm to 75, and carved out a niche as nonprofit experts. While the firm’s roots are firmly planted in Houston, we provide services for more than 700 audit and tax clients throughout the state of Texas and other states. We’re proud to say we’ve earned a strong reputation as the go-to firm for tax-exempt entities in the Houston area.
