How We Can Help


People We've Helped


Mesothelioma is a cancer caused by asbestos exposure. Asbestos manufacturers knew of the dangers, yet failed to warn, train or protect. CPSM's goal is to help those already injured and to make sure it doesn't happen to others.

When Experience Matters, We Are By Your Side

Representing families impacted by mesothelioma and other asbestos-related cancers is our specialty, and has been for more than 30 years. Clapper, Patti, Schweizer & Mason are mesothelioma attorneys with a long history of success and have obtained hundreds of millions of dollars in recoveries for our clients.


Mesothelioma is a serious cancer primarily associated with asbestos exposure. New treatments that are available for mesothelioma patients offer hope for improved survival and quality of life. However these treatments can be expensive. Our job is to obtain monetary compensation from those responsible so you and your family can focus on fighting mesothelioma without the stress of financial worry.

Mesothelioma Is Our Specialty

In the 30-plus years that we have been specializing in mesothelioma cases, we have represented hundreds of workers who were exposed to asbestos in virtually every kind of industrial setting. If you or a loved one has been diagnosed with mesothelioma, call us today to see how we can help you obtain compensation to cover cost of treatments and secure your family's financial future.
