Strategic Affiliations

Part of the Firm’s business model is to create strategic affiliations with other firms and attorneys that have specialized expertise in various areas so we can bring in their expertise when needed and provide cost effective solutions for our clients. In addition, Stone & Magnanini LLP is actively engaged in co-counsel relationships in a number of matters and has access to both their resources and expertise in appropriate cases. Through these affiliations, we have the ability to create a legal team that is as large or small as is necessary for the particular matter.
