Reviewed 2026-09-29; updated 2026-09-29. ## Marsh McLennan Agency Review Score Review Score: 8.2 / 10 from 2 rated sources, equally weighted. Each eligible numerical review or satisfaction rating is converted to a score out of 10, then given equal weight. Duplicate source URLs count once. A rating with a stated source, entity, product, or population limitation may be excluded from the average while remaining visible as source evidence. BBB letter grades use a rough academic GPA conversion: A+/A = 10, A− = 9.25, B+ = 8.25, B = 7.5, B− = 6.75, C+ = 5.75, C = 5, C− = 4.25, D+ = 3.25, D = 2.5, D− = 1.75, F = 0. This is our approximation, not BBB’s formula. Complaint measures and missing ratings are excluded. Sources can cover different products, locations and years; this is a source-rating average, not a pooled customer score. Reliability Score is shown separately. ## Marsh McLennan Agency Ratings by Review Source in 2026 ### Marsh McLennan Agency Reviews on Trustpilot Score: 6.4 / 10 (original: 3.2 / 5). Status: Found. Checked 2026-09-29. Scope: Trustpilot profile for marshmma.com, MMA's own domain. Unclaimed; MMA has not invited reviews. Trustpilot shows 3.2 out of 5, but from a single 1-star review posted in 2022. One review is too few to say anything about MMA's typical service. [8](https://www.trustpilot.com/review/marshmma.com) TrustScore: 3.2 (out of 5); 1 reviews; checked 2026-09-29 ### Marsh McLennan Agency Reviews on Trustpilot Score: 2.6 / 10 (original: 1.3 / 5). Status: Found. Checked 2026-09-29. Scope: Trustpilot page for marsh.com, the global Marsh brand (mostly individual and non-US customers). This is a different entity from MMA. Excluded from Review Score: This page rates the Marsh brand (global, largely non-US and household customers), not the US MMA business. Marsh's page shows 1.3 out of 5 from 115 reviews, mostly one-star, about renewals and service. We show it for context only. It is not an MMA rating, and the UK Marsh Commercial page was not used. [7](https://www.trustpilot.com/review/www.marsh.com) TrustScore (Marsh brand): 1.3 (out of 5); 115 reviews; checked 2026-09-29 ### Marsh McLennan Agency Reviews on BBB Score: 10.0 / 10 (BBB grade A; approximate academic conversion). Status: Found. Checked 2026-09-29. Scope: BBB San Diego-area profile for Marsh & McLennan Agency LLC (accredited). MMA has separate BBB profiles per office; Dayton and Schaumburg both show A+. BBB gives this profile an A grade. That grade reflects BBB's own criteria, not customer satisfaction or insurer strength. [9](https://www.bbb.org/us/ca/san-diego/profile/insurance-services-office/marsh-mclennan-agency-llc-1126-3000103) BBB business grade: A ### Marsh McLennan Agency Reviews on BBB Status: Found. Checked 2026-09-29. Scope: Same San Diego-area profile; zero customer reviews. No client-count denominator. BBB lists four complaints closed in three years and zero customer reviews. One is a commercial vehicle cancellation dispute and one is a personal-lines claim. Not counted in the score. [1](https://www.bbb.org/us/ca/san-diego/profile/insurance-services-office/marsh-mclennan-agency-llc-1126-3000103/complaints) [2](https://www.bbb.org/us/ca/san-diego/profile/insurance-services-office/marsh-mclennan-agency-llc-1126-3000103/customer-reviews) Complaints: 4; closed in the last three years (checked 2026-09-29) ### Marsh McLennan Agency Reviews on NerdWallet Status: Not found in reviewed sources. Checked 2026-09-29. Scope: Checked by exact company name; not a full site review. We found no NerdWallet review of Marsh McLennan Agency. That does not mean none exists. [6](https://www.google.com/search?q=site%3Anerdwallet.com+%22Marsh+McLennan+Agency%22+insurance+reviews) ### Marsh McLennan Agency Reviews on J.D. Power Status: Not found in reviewed sources. Checked 2026-09-29. Scope: Checked by exact company name. J.D. Power’s small-commercial study ranks insurers, not brokers. We found no J.D. Power study that rates MMA. That does not mean none exists. [4](https://www.google.com/search?q=site%3Ajdpower.com+%22Marsh+McLennan+Agency%22+insurance+study) ### Marsh McLennan Agency Reviews on NAIC Status: Not applicable. Checked 2026-09-29. Scope: NAIC complaint data covers insurance companies, not brokers, so it does not describe MMA as a broker. Excluded from Review Score: NAIC complaint indexes measure insurers, not an agency. No NAIC complaint index applies to MMA. We do not borrow any insurer's index. [5](https://www.google.com/search?q=site%3Anaic.org+%22Marsh+%26+McLennan+Agency+LLC%22+consumer+complaint) ### Marsh McLennan Agency Reviews on ConsumerAffairs Status: Not found in reviewed sources. Checked 2026-09-29. Scope: Checked by exact company name; not a full archive review. We found no ConsumerAffairs reviews of MMA. That does not mean none exist. [3](https://www.google.com/search?q=site%3Aconsumeraffairs.com+%22Marsh+McLennan+Agency%22) ## Trustpilot shows 3.2 from one review Trustpilot shows 3.2 out of 5 for marshmma.com, but it comes from one review posted in 2022. One review can't tell you how MMA usually treats clients. [8](https://www.trustpilot.com/review/marshmma.com) MMA hasn't claimed the page or asked clients to review. [8](https://www.trustpilot.com/review/marshmma.com) ## BBB gives one MMA office an A and lists four complaints BBB gives the San Diego-area MMA profile an A. That grade is BBB's own rating, not client satisfaction. Each MMA office has its own BBB profile, and other offices we saw show A+. [9](https://www.bbb.org/us/ca/san-diego/profile/insurance-services-office/marsh-mclennan-agency-llc-1126-3000103) That profile lists four complaints closed in three years and no customer reviews. One is a commercial vehicle cancellation dispute, and one is about a personal-insurance claim.

That is the global Marsh brand, mostly individual and non-US customers, not the US business MMA runs. [7](https://www.trustpilot.com/review/www.marsh.com) We show it for context only and don't count it toward MMA's score. [7](https://www.trustpilot.com/review/www.marsh.com) ## What Counts Toward the Marsh McLennan Agency Review Score? Two things are counted: the one-review Trustpilot rating for marshmma.com and BBB's A grade, which is BBB's own rating, not customer stars. The Marsh brand rating and the BBB complaint count are left out. NAIC complaint data covers insurance companies, not brokers, so it doesn't apply. [8](https://www.trustpilot.com/review/marshmma.com) [9](https://www.bbb.org/us/ca/san-diego/profile/insurance-services-office/marsh-mclennan-agency-llc-1126-3000103) [7](https://www.trustpilot.com/review/www.marsh.com) [5](https://www.google.com/search?q=site%3Anaic.org+%22Marsh+%26+McLennan+Agency+LLC%22+consumer+complaint) ## Marsh McLennan Agency Reliability Score - Broker Reliability Score: - / 10 (unavailable).

Power or ConsumerAffairs reviews of MMA. That doesn't mean none exist. - One Trustpilot review is too little to judge MMA's service. - BBB profiles are per office, so one office doesn't speak for all of them. - MMA is a broker, so reviews of the insurers it places coverage with are a separate matter. ## What Should You Ask Marsh McLennan Agency Before You Buy? - Which office and account team would handle my business? - Which insurers do you place coverage with, and how do you choose? - How are you paid, through commission, a fee, or both? - Who do I call when I have a claim? ## Disclosure About Our Marsh McLennan Agency Review Research Spot, a product of Tools for Enlightenment, publishes this research and works in the commercial insurance market. ## Sources for Marsh McLennan Agency Reviews 1.

Power, NAIC, Trustpilot, ConsumerAffairs, and BBB. Additional relevant sources may also appear. Platforms may cover different products, time periods, and groups of customers, and their metrics use different methods. The Review Score combines numerical ratings and approximate BBB grade conversions on a 10-point scale, with equal weight per source. A BBB letter grade describes BBB’s view of a business; customer star ratings are a separate measure. An NAIC complaint index compares complaint volume with expected volume for a company’s size and is not a customer rating.
