Why Choose Us

How We Are Different

Unlike traditional, multi-practice professional service firms, RSZ focuses solely on forensic accounting, litigation consulting, and related disciplines. We differentiate ourselves from other firms providing similar services in many ways:

  • Dedication to forensic services: investigative accounting, economic analysis, business and asset valuation, and electronic data technology.
  • A focus on a high-level of confidentiality, and responsiveness in delivering client service.
  • We do not offer audit and tax services; therefore, we are better-situated to serve our clients without the seasonal workload compression problems of traditional accounting firms. As a result, we have significantly fewer conflicts of interest while avoiding seasonal demands on our professional staff.

Our Mission

Our mission is to provide accurate, independent, and insightful forensic accounting services that empower clients to make informed decisions, resolve disputes effectively, and achieve favorable outcomes in legal and financial matters.

Our Vision

We strive to be a leading forensic accounting and litigation consulting firm in New York, recognized for our integrity, precision, and ability to simplify complex financial issues into clear, actionable insights.

Philosophy & Principles

Our Client Service Philosophy & Guiding Principles

At RSZ, our core standards are at the forefront of our professional service offerings. Our client service philosophy and guiding principles are essential in successfully executing complex investigations and providing clear, independent understanding of the facts of issues involved. These Guiding Principles include the following:

Early Involvement:

In any engagement, a seasoned professional will tell you it is imperative that they are involved from the outset of the investigation. This will allow counsel to gain a full and thorough understanding of the facts surrounding the allegations and aid in the appropriate measurement of damages. As a result, the team is better prepared to anticipate inquiries and issues, and address any challenges. At RSZ, our extensive experience and uniquely specialized knowledge provides counsel with an additional resource in evaluating and developing discovery requests and interrogatories.

Objectivity and Fairness:

The financial professionals at RSZ understand that a company’s internal management and staff know its business better than anyone. As such, the experience and insights of these personnel may be utilized to gain a working knowledge and an appropriate basis for our analyses. This information, coupled with historical performance metrics, and augmented with independent outside research, provides objective criteria in the determination and/or evaluation of damages.

Time-Tested Methods:

Our professionals adhere to the guiding principles and standards of practice in our profession, including the Association of International Certified Public Accountants (AICPA) and the Association of Certified Fraud Examiners (ACFE). We perform thorough research to identify the most competent supporting records and develop an appropriate investigative approach to establish a defensible basis for conclusions. As rebuttal experts, our professionals contest unsupportable methods of damage calculations or call for unreasonable speculation. Our experienced and multi-disciplined forensic team has the knowledge and experience to assist and advise counsel when engagement priorities shift in today’s ever-changing litigation environment when the focus of the loss analysis must shift to a valuation theory to accurately quantify damages.

Clear and Effective Communications:

A critical element of any engagement is the ability to clarify and communicate complex theories, transactions, and methodologies to a lay audience. A damage analysis that is “brilliant” in its calculation, but lacks effective explanation and communication, is of limited value. Our professionals are proficient at presenting clear explanations of complex financial investigations and analyses. In addition to being CPAs and forensic accountants, we are also educators. All RSZ Partners are experienced adjunct faculty and lecturers to the accounting, legal, and investigative professions, giving CPE and CLE presentations to local, state, national, and international audiences; and publishing in peer-reviewed professional publications. This experience enhances our collective ability to provide clear and concise explanations, delivered in non-technical, easy-to-understand language, that assists counsel, their clients, and triers of fact in arriving at well-informed decisions.
