Meet Our Mental Health Experts

Amanda Gwardys-Cook, PMHNP – Founder & Lead Practitioner
Board-Certified Psychiatric Mental Health Nurse Practitioner
With over 20 years of healthcare experience, I have dedicated my life to helping others achieve mental wellness. I understand how mental health impacts all areas of life—personal, professional, emotional, and physical well-being. Through comprehensive psychiatric evaluations, personalized treatment plans, and holistic care, I aim to help individuals overcome challenges such as anxiety, depression, ADHD, PTSD, and addiction.

Candace Guangorena – Administration Assistant
Hi, I’m Candace! I’m a wife, a mom to an energetic 8-year-old, and happiest when I’m outdoors in the sunshine. I love exploring nature, traveling, and picking up new hobbies. Recently, I joined a book club and started learning to sew on my very first machine.
I hold a bachelor’s degree in Sociology from Cal State Fullerton, and once motherhood slows down, I plan to pursue my dream of becoming a nurse.
I’m excited to be part of Estrella Cognitive Care and to share my care, curiosity, and energy with the team.
