My Approach

I understand that life is complicated and there are many different reasons why someone would need my services. I have understanding of, and compassion for, every situation in which an individual may find themselves.

Furthermore, I treat all clients with dignity and respect, regardless of the crimes they’ve been charged with. I protect my client’s in an unforgiving system, hold the justice system accountable, and communicate regularly, because my clients have the right to know what’s going on with their case.

After spending more than a decade prosecuting these cases, I have the advantage of knowing the mindset, motivations, and tactics the prosecution uses, and wield that knowledge for my client’s benefit.
