David Raymond Mugridge

The practice of law in the area of Criminal Defense requires a constant dedication to several important concepts that should motivate an attorney and upon which I always focus in my office. Foremost is my firm belief in the supremacy of the Constitution and the rights contained therein. I strive to defend the fundamental rights of everyone I represent. This includes, not exclusively, the right to effective assistance of counsel and the inviolable right to an aggressive defense.

After starting my legal career as a research attorney for the Presiding Justice of the 5th District Court of Appeals, I realized that there was a real need for qualified, ethical attorneys in the field of criminal defense. I turned down an offer to work at the District Attorney’s Offices, and dedicated my life and career to criminal defense in the trial court, and criminal appeals and writs. I enjoy the challenges of difficult cases and I have focused most of my practice in the area of murder cases, especially in special circumstances and death penalty cases.

If you or a loved on are in a situation where you need the assistance of a dedicated, successful criminal attorney, I invite you to contact me, or my associate. We strive for excellence in service and compassion for the needs of our clients. Let us help you.
