Meet Our Firm
How It Works

A simple, stress-free process.

From your first call to filing day — and every season after — here’s what working with us looks like.

Get to know you

A conversation about your goals, your history and what keeps you up at night.

Gather & organize

Bring documents in any form — paper, PDF or accounting software. We’ll sort it out.

Plan & prepare

We apply current tax law to minimize your liability today and in the years ahead.

Support year-round

Questions, notices or new opportunities — we’re a phone call away all year.

Specialty Practice

A “pastor” to pastors.

Many firms claim to work with clergy. We focus on clergy. Roger is the author and presenter of the seminar “Clergy & the I.R.S.” and serves ministers from Alaska to Arizona.

  • Housing allowance planning & documentation
  • Dual-status & self-employment tax guidance
  • Church financial planning & advising
Clergy Tax Services
“
Roger is always very attentive to the particulars of each person’s tax situation. Through the years, we’ve sent many of our friends to him because he is the most knowledgeable and experienced tax professional in the area dealing with the intricacies of the clergy.
