ORIGEN

From Rice to Northern Arizona

Matthew Poirier earned a Bachelor of Arts in English from Rice University before attending the University of Arizona’s James E. Rogers College of Law, and was admitted to the Arizona Bar in 2006. He founded his Flagstaff practice in 2015, per the firm’s Yelp and directory listings, building a docket that spans personal injury and criminal defense — including DUI matters — across Coconino County and the surrounding region. He is proficient in Spanish, which the firm states allows him to “effectively assist a diverse range of clients.”

PRÁCTICA

Where the Firm Concentrates

On the personal injury side, the firm’s practice pages cover auto and pedestrian accidents, medical malpractice, dog bites, and motorcycle and trucking accidents, with particular emphasis on collisions along the I-40 corridor — the primary east-west highway through Flagstaff and one of the region’s significant sources of serious vehicle-accident litigation. The firm also maintains a criminal defense practice. Its geographic reach extends beyond Flagstaff proper into Sedona, Williams, Page, Tuba City, and Winslow.

HISTORIAL

What’s Publicly Verifiable

One published account describes Poirier winning an appeal in an assault case stemming from a client “trying to break up a” fight, and a separate published account describes securing a suppression ruling that returned $28,000 to a client following a civil forfeiture action — both criminal-side results rather than personal injury recoveries. Awesome Attorneys did not find an itemized personal injury results page published by the firm, and no personal injury dollar figures are reported in this profile for that reason.

Note: past results, where reported by any firm, do not guarantee or predict future outcomes; every case is unique.

LA VOZ DEL CLIENTE

Lo que reportan los clientes

One published client review states: “I absolutely loved working with Matthew! He’s a great person and even a better lawyer. Communication was amazing and his help comforted me during an otherwise terrible experience… And if you’re worried about prices, he’s more the comfortable to set up a payment plan and make everything a lot less difficult.” Another reviewer, describing a matter in which Poirier was not obligated to take the case, writes: “He had every right to turn me down and say no but Mr. Poirier was by my side the whole way thru… he still cared and showed me how to be different.”

COMUNIDAD

Más allá de la sala del tribunal

Poirier’s LinkedIn profile identifies him as executive director of a youth basketball organization, alongside his legal practice — a civic role distinct from his casework. Awesome Attorneys did not find additional documented charitable or civic initiatives specific to the firm beyond this and notes the gap rather than filling it with unverified claims.

RECONOCIMIENTOS

Posición entre colegas

Martindale-Hubbell lists the Law Office of Matthew J. Poirier, PLLC as having received a Client Champion award in 2026 — an award based on the quantity and quality of client reviews on the Martindale platform — and the firm’s Martindale profile is associated with an AV Preeminent designation, the directory’s highest peer-review rating standard, awarded when a substantial number of an attorney’s peers rank their legal knowledge, communication skills, and ethical standards at the highest level. Awesome Attorneys did not independently re-verify current AV Preeminent status and recommends confirming directly with Martindale-Hubbell before republication. Awesome Attorneys did not find a Super Lawyers or Best Lawyers listing for Poirier at the time of writing.

LA LEY

El contexto legal de Arizona, en lenguaje sencillo

Readers considering a personal injury claim in northern Arizona should understand a few ground rules. What follows is general information, not legal advice.

El reloj de dos años. Arizona’s statute of limitations for personal injury claims is generally two years from the date of injury (A.R.S. § 12-542).

Demandar al gobierno es más rápido y más estricto. Claims against Arizona public entities — including claims arising on federally or state-maintained highways like I-40 — require a formal notice of claim within 180 days (A.R.S. § 12-821.01) and a lawsuit within one year (A.R.S. § 12-821).

La culpa se comparte, no es todo o nada. Arizona follows pure comparative negligence (A.R.S. § 12-2505).

Tribal land adds complexity. Because the firm’s service area includes Tuba City and other communities on or near the Navajo Nation, clients should know that accidents occurring on tribal land can raise separate jurisdictional questions distinct from ordinary Arizona state-court personal injury practice — worth raising directly with counsel early in any such case.

EVALUACIÓN

La perspectiva de Awesome Attorneys

The Law Office of Matthew J. Poirier offers a genuine combination increasingly rare outside Arizona’s largest firms: a peer-rated AV Preeminent designation, Spanish-language capability, and more than 15 years of courtroom experience across a wide swath of northern Arizona, from Flagstaff proper to Sedona, Page, and the Navajo Nation border communities. Client accounts specifically praise personal attention and a willingness to take on cases without a clear financial upside, consistent with the firm’s I-40 corridor and rural-Arizona service focus.

The honest trade-off: this is a mixed criminal-defense-and-injury practice, not a dedicated PI boutique, and Awesome Attorneys could not locate a published personal injury results history to independently verify the firm’s track record in dollar terms. For northern Arizona clients — particularly those in Coconino County’s more remote communities — who value a locally rooted, peer-rated attorney over a large firm’s marketing budget, this firm merits a consultation.
