About me

I fight for our clients rights and do not force them to settle.

I try many Workers' Comp Cases.

I also handle specialized first responder casees for police, corrections and firefighters for heart disease and hypertension.

Most of our referals come from other lawyers.

I also serve on the committee who makes the test for attorneys to become board certified in Workers Comp
