About Dr. Perez

Education and Experience


Dr. Perez graduated from Kean University in Union, New Jersey with a bachelor’s degree in Psychology with a minor in Criminal Justice.  Recognizing the immediate need for specialty training to provide forensic mental health services, Dr. Perez completed doctoral training at Alliant International University at Fresno, California in Forensic Psychology.  Dr. Perez is licensed under the California Board of Psychology (#PSY25139) and is a member of the American Psychological Association.

“I’ve always been fascinated with the functions of the brain and how that translates into behaviors. As I continued to advance my career as a psychologist, I learned that understanding these mechanisms provided essential insights for my clients and their families. Many of the clients I serve have significant struggles, and the answers my assessments provide can help give them a better quality of life and a brighter future.That is what helps keep me passionate about my work.” ​

“I have worked with clients who struggle with Severe and Persistent Mental Illness (SPMI) for many years. After beginning to provide conservatorship evaluation services, I recognized what a difference I can make – stability, awareness, and greater capacity to have their needs met. Similarly, with expert testimony I am able to share my experience and education to help families and legal teams make clear decisions about client care, mental capacity, and psychosocial issues.”
