This award is named in honor of the National Register’s first Executive Officer, Alfred M. Wellner, PhD. The Wellner awards, offered for research and clinical excellence, are the highest honors bestowed on a Registrant to commemorate numerous and significant contributions to psychology during a distinguished career.

His continual legislative, professional, and personal advocacy has advanced the standing of health service psychologists as health care practitioners. His leadership, including a term as APA president, has inspired other psychologists to follow in his footsteps.

Upon receiving the award, Dr. DeLeon said, “Having worked closely with Al Wellner from the very beginning of the National Register, this recognition is truly special and brings back many fond memories of his vision, dedication, and commitment to psychology.  Mahalo.”
