FH Promise. The FH Promise is a set of principles that guides how the firm delivers legal services and works with clients. The firm conducted extensive research, spoke to lawyers and professional staff throughout the firm, as well as to clients, about the elements of exceptional client service. From this we developed the FH Promise and established firm-wide guidelines for how we provide first-class service to our clients. Whether a client chooses our firm to defend a lawsuit, assist with a labor matter, help with benefit or immigration issues, or provide timely counseling to avoid litigation, we are committed to making that experience the best it can be.
