Meet Our Team

For years, we have worked alongside business owners and individuals offering steady, practical guidance that supports real-life decisions. Our focus has always been long-term relationships built on trust, consistency, and clear communication.

We partner with clients in industries that shape our local economy, including oil and gas, construction, agriculture, real estate development, nonprofit organizations, and the medical field. This experience allows us to see beyond the numbers and understand the day-to-day realities and pressures our clients face.

Our clients value having a CPA who is present, approachable, and invested. Someone who understands their business, keeps their goals in mind, and is available throughout the year when questions come up. We take pride in being responsive, easy to work with, and genuinely committed to helping our clients move forward with confidence.

A Thoughtful Approach
to Accounting

We bring strong technical expertise, ongoing education, and up-to-date tools to every client relationship. Just as important, we bring care and perspective. We take the time to explain, answer questions, and help you feel comfortable with the decisions you are making.

Our goal is to reduce stress around taxes and finances so you can focus on running your business and enjoying your life outside of it. Whether you are growing, planning, or preparing for the future, we are here to support you with clear guidance and steady advice.
