Mental health practitioner

Amanda Gwardys-Cook PMHNP – Owner

Greetings, I am a Board Certified Psychiatric Mental Health Nurse Practitioner and have dedicated my life to helping others achieve mental wellness. I have over 20 years of experience in healthcare and know the impact mental health can have on us professionally and personally. Mental health directly impacts our abilities to function to our fullest potential and is the key component in achieving overall wellness  physically, emotionally, professionally and personally. 

Tuyet Lam – PMHNP 

As a Psychiatric Mental Health Nurse Practitioner, I, Tuyet Lam, am here to guide you through this journey with understanding and care. Mental health is more than just a diagnosis; it’s about your overall well-being, quality of life, and how you feel about yourself, and that’s where I can help make a difference. My role is to provide you with a comprehensive approach to care – this includes thorough psychiatric evaluations, accurate diagnoses, and evidence-based medication management, combined with individualized psychotherapy. I bring over 15 years of rich experience in mental health care, having worked with a diverse patient population in the clinics & hospitals. Together, we can work towards a healthier, happier you!

Emily Santos – Administrative Assistant 

Hi, my name is Emily Santos! I graduated with a degree in Biomedical Science from ASU Barrett The Honors College in the spring of 2023 completing my thesis in appearance-based shame in medicine. I am a registered CNA and plan to earn my masters in Physician Assistant studies. However, I am also very passionate about mental health and believe it is essential in treating the whole person. At Estrella Cognitive Care I primarily focus on intake appointments, scheduling, and patient care. In my free time I like to listen to live music, travel, and run my online clothing store
