Also known as limited scope representation, allows an attorney and client agree to limit the scope of the attorney’s involvement in a lawsuit, leaving the responsibility for some aspects of the case to the client.  This gives the client more control, and reduces attorney fees.  Casey can draft pleadings, help you navigate procedural rules and deadlines, or provide coaching so you can present your case to the Court.


Many mistakenly think they cannot afford a lawyer.  That should not be trued in today’s world. I leverage staffing and technology to maximize efficiency and offer a variety of fee options including flat fees, hourly rates, or contingency.
