About HSNO

Corporate Background

Founded in 1973, Hagen, Streiff, Newton & Oshiro, Accountants, PC (“HSNO”) has a broad range of capabilities in its 35 year existence. We are a leading, internationally recognized accounting and consulting firm, concentrating on forensic accounting, litigation support and insurance claims accounting and investigation services. Our professionals, located in offices across the United States, have a broad range of experience — from financial analysis and review of relevant economic issues to expert witness testimony, evidence gathering and administrative support.

We pride ourselves on prompt service throughout the world. Since the firm does not engage in the preparation of income tax returns or audited financial statements on a recurring basis, our staff is available on short notice. The highest education and experience is required of all personnel — All managers and partners abide by strict professional standards promulgated by the American Institute of Certified Public Accountants or another nationally recognized certifying or accrediting organizations.

We hope you will take the time to look over our site. You will find descriptions of the many services available to you.

Hagen, Streiff, Newton & Oshiro, Accountants, PC was founded in 1973 as William K. Kinsel, an Accountancy Corporation. Subsequent growth contributed to re-naming the firm in 1997 to Kinsel, Streiff & Newton, LLP. Continued expansion and the end of the association with Kinsel Accountancy Corporation prompted the change on January 1, 2000 to Hagen, Streiff, Newton & Oshiro, Accountants, PC. Our current name showcases the national presence and character of our firm by recognizing the principals in many of our offices.
