The MPM Group, Inc. is a New Jersey litigation-support and investigations firm that also markets federal and state prison consulting under the banner "Federal Prison Experts."[1] Incorporated in January 2000 and based in Marlton, New Jersey, it is among the longer-operating firms appearing in prison-consulting search results.[2]
The firm is unusual among its peers in that it names none of its personnel on its own website. Its "Senior Staff" page describes eight leadership roles by function — chief operating officer, legal advisor, complex criminal investigations, complex financial investigations, narcotics and conspiracy investigations, foreign operations, training and security, and inmate advocacy — without attaching a name, biography, or credential to any of them.[3] Two principals are nonetheless identifiable through third-party sources: Nancy H. Olson is listed as owner and president in Better Business Bureau and business-directory records, and Vito Guarino, a former Drug Enforcement Administration Special Agent in Charge, is named as chief operating officer in a 2023 press release and in the firm's New Jersey Licensed Private Investigators Association listing.[2][4][5] The firm holds Small Business Administration Woman Owned Small Business designation.[4]
Prisonpedia Rating: Caveat Emptor
Prisonpedia weighs each federal prison consultant's independent client reviews, verifiable professional background and credentials, media and public presence, and any documented complaints or disciplinary history. As of our most recent review, The MPM Group, Inc. holds a Caveat Emptor rating.
⚠ The firm discloses nothing about who does the work. Prisonpedia rates The MPM Group Caveat Emptor on the firm's own disclosure, not on any finding of wrongdoing and not on service quality, on which we have no evidence in either direction.
The problem. MPM's Senior Staff page lists eight leadership roles — chief operating officer, legal advisor, complex criminal investigations, complex financial investigations, narcotics and conspiracy investigations, foreign operations, training and security, and inmate advocacy — and attaches no name, no biography and no credential to a single one of them.[3] The firm's marketing rests on collective claims: former U.S. Department of Justice criminal investigators, former Bureau of Prisons senior staff, a staff averaging twenty-five years in federal and state law enforcement.[1] A prospective client reading the firm's own materials cannot attach any of that to a person, cannot learn who would handle their case, and cannot check that person's record. Prison consulting is unregulated — no license to verify, no board to complain to, no body that can sanction anyone — so a client's only real protection is knowing who they are dealing with. Every other consultant profiled here puts a named individual at the front of the practice. A client should not have to run an investigation to find out who they are hiring.
In fairness — what is findable elsewhere. Two principals can be identified through third-party sources, and Prisonpedia records them here rather than leaving a false impression of anonymity. Nancy H. Olson is listed as owner and president in Better Business Bureau and business-directory records, though no professional background is published for her.[2] Vito Guarino, named as chief operating officer in a 2023 press release and in the firm's New Jersey Licensed Private Investigators Association listing, spent 31 years at the Drug Enforcement Administration — a decade undercover in Miami, supervisor in Atlantic City, acting Special Agent in Charge in Philadelphia, and Special Agent in Charge of the Caribbean Office covering Puerto Rico, the U.S. Virgin Islands and 21 island nations — rising to the Senior Executive Service.[4][5] That is a genuine and checkable federal record, and it partly corroborates the firm's experience claims. It does not cure the firm's own silence: nothing tells a client that Guarino, rather than an unnamed contractor, would be the person on their case. The corporate record is otherwise long and clean — incorporated 11 January 2000, no Better Business Bureau complaints, though BBB rates the firm "Not Rated" and it has not sought accreditation.[2] Note also that prison consulting is one line in a broad investigations business here, not a dedicated practice.
Before retaining: get the name of the individual who will handle the case, their specific DOJ or BOP position and dates, and put it in the engagement letter. This rating will be revised to Neutral if the firm publishes named staff with verifiable credentials.
