Landis, PLLC specializes in complex projects and sites that require unique custom designed environmental solutions.  Sometimes the environmental solution requires Landis to create techniques never previously used, and sometimes we apply existing scientific solutions, but  in totally new ways. The creation of unique solutions occurs as a response to the client’s direction or based upon our need to find a better environmental solution for the client.
