TJCAA goes "Green"
As a firm, we are committed to implementing “Green” practices in our day-to-day operations. Examples of this policy include purchasing recycled products, marketing our services using electronic methods, using technology to transmit documents to and from clients, as well as eliminating the use of bottled water and alkaline batteries. Many of our employees join in the challenge by using public transportation for travel to and from work. In addition, two members of our staff are LEED Accredited Professionals and can provide their expertise in this area when requested. All of this supports our goal to be green.
