New Firm? Yes. NEW TO THE BUSINESS? Definitely not.

About us

At Mitchell Semsel Callen, PC, forensic accounting is not a sideline.  Our firm is dedicated to providing our clients with economic analyses in litigation contexts and service as expert witnesses in court.

We've represented thousands of clients in economic damages cases and we have the experience that you're looking for. We're always willing to work with you on our fees and services. We're simply here to help you.

As former partners at Campos & Stratis, we have over 90 years of combined experience in forensic accounting. Our team of financial professionals is dedicated to investigative accounting and financial impact analysis. We do not have a general accounting or tax practice. Our office is staffed with full-time forensic accountants, not reassigned auditors. This means clients are assured of the avoidance of actual or potential conflicts of interest.


Our clients are predominantly commercial property and liability insurance carriers, law firms and corporations. We have worked on thousands of cases for virtually every type of business, industry and coverage. Whether in the field, office, or courtroom, our vast experience as consultants and expert witnesses means fast, flexible, cost-effective service.

Give us a call. Drop us an email.  We’d love to put our experience to work for you.
