Celebrating 35 Years of Serving Arizona and
Saying Farewell to our Founder

Grass, Coffey & Scharlau (GCS) began in 1980 when an eager Leon Grass started his CPA practice with a heart for serving the valley. His goal was to provide personalized service that is often lost in larger firms. Thirty-five (35) years later, GCS is a full-service accounting firm dedicated to providing a wide range of accounting & tax services to businesses large and small as well as individuals and non-profits. While GCS specializes in such areas as construction, real estate, manufacturing, physicians, and non-profit entities, all of our individual and business clients find themselves right at home when meeting with us. We take great pride in offering warm, honest & confidential meetings our clients have come to respect. We tailor our services to meet the specific needs of each client when planning for their future & addressing their past. Whether it is income tax planning & preparation or assurance services, GCS is proud to continue providing the valley with the highest degree of knowledge, professionalism, and guidance. We look forward to another 35 years and more.

As we celebrate 35 years of serving Arizona, we cheerfully say Happy Retirement to Leon. Leon has been the patriarch of GCS and guided the firm through the many changes and challenges our clients in Arizona have experienced over the past 4 decades. He will be greatly missed but we couldn't be happier than to see him retire in northern Arizona where he loves to garden, fish and spend time with his family. As his legacy lives on, we wish him well and say, "See you later dear friend; you'll be missed!" Enjoy your retirement; you have earned it.
