The reviewed public sources do not establish a representative customer rating for The Baldwin Group’s commercial advisory business. BBB pages show different legal entities: an A+ regional insurance-agency grade with zero listed reviews and complaints for The Baldwin Group Mid-Atlantic, LLC, and an A- grade plus six complaints in three years for The Baldwin Group Personal Insurance, LLC. A 2026 personal-lines complaint describes delayed refund handling. A separate National General auto review mentions a Baldwin referral but concerns insurer policy administration.
