Former Mayo Clinic Nurse Gets 3 Years for $420 Million Fraud Scheme

From Operating Room to Prison Cell

Matthew Onofrio, the former Mayo Clinic nurse anesthetist turned commercial real estate investment "guru," was sentenced this week to three years in prison and ordered to pay $5.39 million in restitution to a Bloomington, Minnesota, bank. The 34-year-old's dramatic fall from healthcare professional to federal prisoner underscores how even trusted medical professionals can orchestrate massive financial crimes.

Over the course of approximately two years, Onofrio completed 68 deals involving $420,564,795 in fraudulently obtained bank loans. In handing down her sentence, Judge Nelson identified Onofrio as the "ringleader and architect of a vast bank fraud." The judge made clear she wanted to send a warning to other would-be fraudsters.

The Sophisticated Deception

Between 2020 and 2022, Onofrio created an elaborate real estate investment program that preyed on new investors eager to break into commercial property markets. Onofrio would secure purchase agreements for commercial properties, then assign them to inexperienced investors at highly inflated prices. His scheme exploited the dreams of aspiring real estate moguls who lacked the capital for multimillion-dollar deals.

To line up inexperienced investors, Onofrio promoted his own financial success and real estate investment strategies in online professional networking groups, in YouTube videos and on a popular podcast called "Bigger Pockets" to craft a reputation as a real estate savant, who had cracked the code of commercial real estate investing. This marketing strategy attracted a steady stream of victims to his operation.

When the lending banks inevitably requested proof of funds, Onofrio temporarily wired the money into his investors' bank accounts, making it appear they actually had the money. If the banks asked about the source of the funds, Onofrio instructed his investors to tell the banks it came from other investments, or they had family money.

Real Estate Empire Built on Lies

Under the name Moose Enterprises LLC, he paid $7.7 million for the historic Massey and Blakely buildings at 16 Second St. SW and 210 First Ave. SW in downtown Rochester in January 2020. Onofrio also was involved with the $12 million purchase of the City Centre complex at 310 S. Broadway in 2020. He later sold the property, for $14 million, in 2021. These high-profile deals helped establish his credibility in the real estate community.

He netted at least $35,745,252 from the scheme before he was caught, and has been sentenced to three years in federal prison. As part of the case, the court seized a $35 million bank account that he had with Premier Bank in Rochester. The massive seizure demonstrates the scope of his fraudulent activities.

Lessons for Investors and Lenders

Onofrio's case reveals critical vulnerabilities in commercial lending practices. His ability to manipulate proof-of-funds requirements and hide secondary loans from primary lenders exposes gaps that other fraudsters might exploit. The scheme succeeded because banks relied heavily on documentation that Onofrio systematically falsified.

The sentence, while substantial, falls short of the six years prosecutors requested and the five-year average for similar crimes. This lighter punishment may reflect his cooperation with authorities and lack of prior criminal history. However, the case establishes important precedents for prosecuting sophisticated real estate fraud schemes that exploit both inexperienced investors and traditional lending institutions.
