Historical Perspective

Kinsella-Marsh Group (KMG) is an outgrowth of a previous firm, Pelton Marsh Kinsella (PMK), founded in 1984 by Gary Kinsella and joined the following year by David Marsh. Kinsella and Marsh re-partnered in 2009 as Kinsella-Marsh Group.


KMG is an independent acoustical, audio-video and low voltage consulting firm with offices in Miami Beach, FL and Dallas, TX. Independent means the firm has no financial interest in manufacturing, distribution, sale or installation of products – i.e., we are a pure consulting firm. As such, KMG is able to provide objective evaluations, opinions, product recommendations and design approaches based solely on the client’s requirements and project design constraints.
