Arthur R Siegel Law Offices

Cornerstone Law Group was formed in 2000 to provide high-quality legal services in a cost-effective and responsive manner. In 2001, the principals of the firm of Tierney, Watson & Healy became associated with the Firm. We became a professional corporation in 2007. We understand that the law is a means to accomplish our clients' business objectives, not an end in itself. As such, we find innovative solutions to our clients' problems. Please see a more detailed description of our values and priorities. As the practice of law has become highly specialized, many law firms have lost the ability to look at the broader picture. Our attorneys, however, have a wide range of skills and expertise, and as such are able to understand a client's entire landscape of issues and objectives. We understand that solutions must be achieved in light of all of our client's circumstances, and not in a vacuum. Please see a more detailed description of the Firm's major practice areas. We are headquartered in San Francisco, and have satellite offices in Los Angeles, San Diego, and Lake Tahoe. However, we represent clients from every geographic area of the country.
