Assessment & Diagnosis

Dr. Zafire Fierro PhD, C.Psych.

Clinical & Counselling Psychologist | Clinical Supervisor | Founder & Director, Atrium Psychology

Languages: English & Spanish

Focus:

Dr. Fierro works with adults, couples, and clinicians seeking a clearer understanding of their internal world. Her practice includes psychological assessment and diagnosis, trauma-related concerns, emotional and relational patterns, and supervision for mental-health practitioners.

Approach:

Dr. Fierro’s style is collaborative, grounded, and insight-driven. She helps clients trace how past experiences, nervous-system patterns, and relational history show up in the present — often in ways that feel confusing, overwhelming, or stuck. Her work is both practical and deep, guiding clients to understand how their mind works so they can respond to life with more steadiness and choice.

She combines structured psychological assessment with therapeutic work that looks at the whole person: emotions, body signals, relational dynamics, and the stories people carry about themselves. Clients often come to her after previous therapy or because they’re ready to explore what’s underneath long-standing patterns.

Clinical Perspective:
At the heart of her work is the belief that people change when they feel understood, safe, and able to make sense of their own responses. She focuses on helping clients build awareness, regulate their nervous system, and reconnect with parts of themselves that have been overlooked or overwhelmed. Her approach invites clarity, depth, and the capacity to move through life with more intention.

Professional Development:
Dr. Fierro has trained widely across trauma, attachment, assessment, somatic, and depth-oriented approaches. She has also completed education in the clinical theory and emerging research on psychedelic-assisted psychotherapy.
This training is educational only; her clinical services do not involve or facilitate the use of psilocybin, MDMA, or other controlled substances.

Dr. Tamarah Chaddah ND, MSCP

Languages: English

Populations
Adults & Women

Areas of Focus

Perimenopause and menopause
Hormonal health and menstrual concerns
Bioidentical hormone therapy (BHRT)
Sleep, mood, and emotional wellbeing
Fatigue, burnout, and stress-related concerns
Weight, metabolism, and energy changes
Preventive and lifestyle medicine
Women's health across midlife

Approach

Dr. Chaddah’s style is collaborative, educational, and deeply individualized. She helps patients understand how hormonal shifts, stress physiology, nutrition, lifestyle, medical history, and emotional wellbeing can intersect and shape how they feel day to day.

Her work combines clinical assessment, evidence-informed treatments, laboratory evaluation when appropriate, lifestyle medicine, nutrition, and hormone-focused care. She takes time to explain what may be happening in the body, what treatment options are available, and how to build a plan that feels realistic, safe, and aligned with each patient’s goals.

Patients often come to her during perimenopause or menopause when they are looking for answers, clarity, and a clinician who can help them connect the dots between symptoms that may have felt confusing, overlooked, or minimized.

Clinical Perspective:
At the heart of Dr. Chaddah’s work is the belief that women deserve to feel understood, taken seriously, and well-informed about their bodies. She focuses on helping patients move from confusion to clarity — understanding what may be driving their symptoms, what options exist, and how to make confident decisions about their health.

Her approach is both practical and whole-person, recognizing that midlife health is not only about managing symptoms, but also about supporting energy, resilience, emotional steadiness, confidence, and long-term wellbeing.

Professional Development:
Dr. Chaddah has been in clinical practice for over a decade and has pursued advanced training in women’s health, menopause care, hormone therapy, mental wellness, burnout, and preventative health. She is a Menopause Society Certified Practitioner and brings a strong clinical focus to supporting women through the hormonal, emotional, metabolic, and physical changes of midlife.

Her work is grounded in education, prevention, and partnership — helping women better understand their bodies and feel more empowered in the next stage of life.
