"One of the lesser known but great successes of clinical supervision over the past 25 years has been Dr. David J. Powell's innovative adaptation of this methodology to the U.S. Navy's alcohol treatment program. Under the title Clinical Preceptorship, it provided licensed and credentialed mentors to the Navy-trained counselors. Dr. Powell started this program in 1976 at the U.S. Naval Alcohol Rehabilitation Center in Norfolk, Virginia. Over the years, he has overseen its expansion to about fifty bases worldwide, from Iceland to Cuba and from Diego Garcia in the Indian Ocean to Sicily in the Mediterranean Sea. The program also operates on the U.S. Navy aircraft carriers. As a former commanding officer of the Naval Alcohol Rehabilitation Center, Norfolk, I have experienced the Clinical Preceptorship Program's great value to the counselors. Further, having the ability to confer with an impartial, knowledgeable person from outside of the organization is of inestimable value to the commanding officer—a person who may or may not have training in the substance abuse field. Dr. Powell's clinical supervision expertise and his vision created a program that helped save the military career and possibly the lives of thousands of Navy and Marine Corps personnel, including my own."
—Capt. Thomas J. Glancy Jr., United States Navy, retired
