About DMO Accounting

I’m Derek Orendorff, CPA and founder of DMO Accounting. I help small businesses simplify their finances, improve cash flow, and make confident decisions: all with secure, cloud based tools and a commitment to first-class client service. Whether you’re in Central Illinois, the Quad Cities, Dallas Fort Worth (DFW), or beyond, you’ll get the convenience of modern technology with the personal connection of a trusted advisor.

Why I Started DMO Accounting

I began my career at a national public accounting firm, where I gained broad experience in accounting, tax, and business advisory. Over time, I noticed the same problem again and again: client service was taking a back seat to volume. Emails went unanswered, calls weren’t returned quickly, and important conversations happened only at tax time.

I started DMO Accounting to change that. My mission is to provide small businesses with the accuracy, clarity, and year-round support they deserve — without the wait.

How I Work

Same-day replies: so you’re never left waiting for answers.

Proactive guidance: through monthly check-ins and advisory sessions.

Clear, accurate reporting: so you always know where your business stands.

Secure, cloud based tools: for speed, convenience, and collaboration.

Personal relationships: that include handshakes, face-to-face meetings, and long-term partnerships.

Beyond the Numbers

Outside of work, I enjoy fishing, camping, and hiking: anything that lets me spend time outdoors. These moments keep me grounded and remind me that the best relationships, in business and in life, are built over time.
