Who We Work For

ALLTHERM impressed me with their ability to meet a very tight schedule which was complicated by structural demo constraints and the worst winter on record. They have never failed me and is a resource in assisting with value-engineering.

Jim Bob helped us out at the Fair Oaks Mall with the value engineering he provided. They ended up orchestrating an Erickson helicopter pick which took 30 minutes, in lieu of the crane service that would take a full week to do the same task! This was invaluable to our client.

Robert L.

Project Manager

Jim has used his professional expertise to make a difference in our communities. He has invested countless hours helping nonprofit organizations, like mine, renovate buildings to provide marginalized people with housing, employment, and life skills in a way that changes lives and makes our community better.

Jim’s value engineering not only saved us money while maintaining the intent of the drawings, but were innovative from a design standpoint. He always thinks of a better way to do something. He is a trusted industry partner and a great source of information.
