I'm Stephanie Patrick-Calvillo, a Board-Certified Psychiatric Mental Health Nurse Practitioner who believes mental health care should be accessible, compassionate, and tailored to each individual. Over the past 15+ years, I've worked with diverse populations—from adolescents facing their first mental health crisis to adults navigating complex psychiatric conditions, and seniors experiencing cognitive and emotional challenges.

My practice is grounded in the belief that effective treatment goes beyond symptom management. I take time to understand your unique story, your strengths, and the factors that shape your mental health. Whether you're dealing with a new diagnosis or have been managing symptoms for years, I meet you where you are with respect and without judgment.

I specialize in treating mood disorders, anxiety, psychotic disorders, personality disorders, substance use concerns, and behavioral issues related to dementia. I've completed advanced certification training because I'm committed to staying current with evidence-based treatments—ensuring you receive care that reflects the latest research.

Beyond clinical work, I'm passionate about mentoring the next generation of healthcare providers. I've mentored nursing and nurse practitioner students from multiple universities, which keeps me grounded and reminds me why this work matters.

When you work with me, you're getting someone who genuinely cares, who's seen mental health challenges from many angles, and who believes deeply in your capacity for healing and growth.

Hi, I’m a psychiatric nurse practitioner who believes everyone deserves to feel heard, supported, and treated with kindness. I create a warm, welcoming, and judgment-free space where you can feel comfortable being yourself. I work with clients experiencing anxiety, depression, stress, mood changes, and other mental health concerns. Along with medication management, I also use supportive therapy techniques, including CBT and motivational interviewing, to help clients build healthy coping skills and feel more confident in their daily lives.

Are you doing the same thing over and over again and expecting different results? Have you tried countless times to change a your behavior? Have you recently left inpatient rehabilitation or a psychiatric ward and need additional support? Do you feel like your mood, anxiety, and depression are running your life? Making these changes can be extremely difficult and cannot be done alone. My name is Lauren Debski. I am a dual board-certified family and psychiatric-mental health nurse practitioner.

I am a psychotherapist committed to helping individuals heal, grow, and navigate life's challenges through compassionate, evidence-based care and hold a Masters in Counseling Psychology, Marriage & Family Therapy. I work w/ clients 24 years & older facing anxiety, trauma, addiction, relationship struggles, stress, and life transitions to help them build resilience, clarity, and lasting change.

Being a therapist is more than a job to me. It is a calling

I believe healing begins with meaningful connection. My work with cancer patients and their families has deeply shaped my understanding of pain, loss, resilience, and the complexities that relationships face during times of crisis. I support adults of all ages in navigating challenges such as anxiety, depression, loneliness, grief, and relationship concerns, offering both compassionate guidance and practical, effective tools for growth and healing.
