Celebrating 35 Years of Serving Arizona

Grass, Coffey & Scharlau, CPAs (GCS) has been a valley of the sun business for over 35 years. The principle value upon which the firm was established is to provide personalized service that is often lost in larger firms. 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, HUD audits, 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 plus years.
