DiRuzzo & Company litigates when numbers are at the heart of the case. For example, Mr. DiRuzzo has litigated partnership disputes between doctors regarding allocation of insurance and medicare payments, a commercial lease where the lease payments to the landowner was a complex calculation of sub-tenant revenues, and a closely held businesses dispute where family members were accused of usurping corporate business opportunities and converting corporate assets for their own personal use.

Mr. DiRuzzo uses his background as a CPA and his advanced degree in accounting to make sense of the accounting and the numbers that are central to high-stakes civil litigation. When most attorneys talk about "complex ligation" they are usually referring to the procedural complexities of a case, not the underlying subject matter. However, most attorneys quickly find themselves unable to parse through the discovery without the aid of a CPA, something Mr. DiRuzzo can do by himself. By being both an attorney and a CPA, Mr. DiRuzzo provides value to his clients as the need for experts - and the time assimilating them into a trial team - is minimized, or even eliminated. If GAAP, GAAS, balance sheets, income statements, and forensic accounting (including tracing of funds) could be at issue in a case, Mr. DiRuzzo's understanding of these concepts reveals itself in high quality legal briefs, oral arguments, trial presentations, and excellent results in high-stakes cases.

Additionally, DiRuzzo & Company has experience litigating against the federal government which aggressively pursues cases involving allegations of violations of consumer protection statutes (e.g. deceptive trade practices), fraudulent billing, and improper reimbursements. Typically, cases against the government are won, or lost, not on procedural grounds, but instead on the business documentation and representations made to the various governmental agencies. Mr. DiRuzzo ensures that the best evidence is identified, obtained, and presented during the course of litigation in order to try to convince the government to drop its case, or, if needed, to be presented at trial.
