LMHS

What LMHS does

LMHS, P.C. is a privately-held certified public accounting and tax advisory firm headquartered in Norwell, Massachusetts, founded in October 1987 by Bryan J. Morrissey and Carl E. Leone. The firm operates from three physical locations — Norwell, MA (headquarters), Hanover, MA (Metro West Boston), and Westlake Village, CA (West Coast) — and is PCAOB-registered and a member of the AICPA National Peer Review Program. Services include corporate and partnership tax preparation and planning, individual tax preparation, audit/attestation services, full-service accounting and bookkeeping, business advisory and consulting, business valuation, estate and trust planning, litigation support, and international/cross-border tax services for engagements in all 50 U.S. states plus Canada.

The firm serves two primary client cohorts: business clients (spanning industries including construction, broker dealers, manufacturing, distribution, nonprofits, real estate development, and equipment rental) and high-net-worth individuals requiring personal tax and estate planning. Pricing is engagement-based, determined by scope, complexity, and time, with multi-year client relationships as the dominant commercial structure. Go-to-market is sales-led and trust-driven, leveraging professional reputation, community involvement through charitable organizations, direct outreach, and referrals; distribution is direct via face-to-face consultations and a secure online client portal. The firm is a member of MGI Worldwide's international network of accounting firms and maintains professional affiliations with AICPA, MSCPA, NACVA, and PCAOB.

LMHS, P.C. has grown organically over 36+ years and pursued modest inorganic expansion with the January 1, 2026 acquisition of the Michael J. Raymond CPA practice. Bryan J. Morrissey continues to serve as Managing Partner, with a partner group of five (Morrissey, Kimberly J. Gagnon, Charles R. Gubitose, Stephen Halko-Sheehan, William E. Synan, and Lyndsey M. Niles) supported by senior managers, senior accountants, tax administrators, and staff accountants. Revenue is generated entirely through professional services fees with no publicly disclosed financial figures.
