Our firm has a proud tradition of professional and community leadership. Members of the firm have held various offices in the State Bar and have chaired  bar committees. Civic achievements include leadership roles in numerous civic organizations. This tradition exemplifies the commitment of our firm to provide quality service to our clients by attorneys who have a dedication to their profession and to their community.

In recent years, the practice of law has become extremely complex. No one lawyer can keep abreast of all legal developments in order to be an effective counselor. Recognizing this, we have developed a team concept to address the latest legal issues and developments in specific areas. While practicing the team approach, we still strive to maintain our individual attorney-client relationships. Our clients, therefore, receive the personal attention and continuity of working with an individual attorney who is familiar with their general needs, and they also benefit from having our attorneys' combined expertise available to them.

Our business team advises clients in all phases of business law including banking, commercial, corporate, environmental and regulatory affairs, credit-debtor relations, bankruptcies, real estate, tax and employee benefits, and labor and employment problems. We serve a wide range of clients, from small beginning entrepreneurs to the mature industry seeking diversification. 

Our firm is also committed to assisting individuals when challenges arise affecting their families, financial affairs, health or individual liberty. Our attorneys have expertise in a wide range of matters, including divorce, custody, personal injury and other matters affecting the individual.  We operate on the principle that we must earn and retain our client's trust in every case, no matter how small. Over the years, adherence to this principle has guided us in serving generations of families and thousands of long-term clients.
