I'm Sherri Crespin, a board-certified Psychiatric Mental Health Nurse Practitioner specializing in complex mental health conditions in adults. With dual board certifications from the American Nurses Credentialing Center as both a Family Nurse Practitioner and Psychiatric/Mental Health Nurse Practitioner, I bring a comprehensive understanding of how mental and physical health intersect to create truly holistic care.

My clinical expertise includes treating trauma and PTSD, personality disorders, substance use disorders, and mood disorders such as depression, anxiety, panic disorder, and bipolar disorder. I'm experienced in managing complex medication regimens and other specialized treatments that require careful monitoring and expertise.

I earned both my Bachelor of Nursing and Master of Science in Nursing from the University of Texas at Austin, where I developed a strong foundation in evidence-based practice. What sets my practice apart is my commitment to treating the whole person—not just managing symptoms, but understanding your unique story, challenges, and goals.

Whether you're seeking psychiatric medication management or comprehensive treatment for multiple conditions, I create a safe, non-judgmental environment where you can openly discuss your concerns and actively shape your treatment plan. I also provide ESA letters when clinically appropriate.

I look forward to partnering with you on your journey toward improved mental health and lasting well-being.

As a therapist and a woman of color, I know firsthand how heavy life’s obstacles can feel when you’re trying to move through the world and still chase your dreams. Maybe you feel disconnected from the people you love, stuck in self-doubt and second-guessing, or worn down by unexpected changes in your relationships. If any of that resonates, please know you don’t have to carry it all alone, and you’re in exactly the right place.

For the past year, I've worked with adults facing serious mental health challenges at one of Los Angeles's largest public health systems, and what I've learned is that lasting change comes from relationships built on trust. Now I'm bringing that experience into private practice, where I can focus on what matters most: your individual progress. I work with people navigating anxiety, depression, and PTSD, and I offer flexible evening and weekend availability via telehealth throughout California. As a PMHNP, I'm here to support your whole mental health journey.

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.

I'm Saby Kirpal, a Psychiatric Mental Health Nurse Practitioner dedicated to providing comprehensive mental health care. I hold Master's degrees from Chamberlain University and Walden University, graduating with Presidential Honors, reflecting my commitment to clinical excellence. My diverse professional background spans inpatient psychiatric hospitals, residential treatment centers, and outpatient clinics, giving me insight into mental health treatment at every level of care. I specialize in treating depression, anxiety, autism spectrum disorders, eating disorders, and substance use disorders across age groups. My experience includes working with children as young as eight through adults in crisis stabilization, residential treatment, and ongoing medication management.

What makes my practice unique is the integration of my nursing background with psychiatric expertise. I understand how physical health, medications, lifestyle factors, and mental health interconnect. Being trilingual in English, Hindi, and Punjabi, with conversational Spanish, allows me to serve diverse communities and appreciate how culture shapes mental health experiences.

I've worked from UCSF Health to community clinics, teaching me that excellent care isn't about the setting—it's about the relationship. Whether you're seeking help for the first time, between providers, or managing ongoing conditions, I'm here to partner with you. My approach centers on listening first, explaining clearly, and making decisions together. Mental health treatment should never feel like something done to you, but rather something we navigate together. I'm committed to creating a space where you feel respected, understood, and genuinely supported.

YOUR story matters, YOUR healing matters. I'm here to support YOU!

My passion for nursing started from a personal place. Watching someone I loved go through illness taught me how important it is to have someone who listens, shows compassion, and treats you like a whole person, not just a diagnosis. I have been a nurse for 27years, with experience in mental health, intensive care, nursing leadership, and teaching. My goal is to provide a safe, supportive, and nonjudgmental space where you feel heard, respected, and cared for,

It is my prayer to build a practice that helps you reach a place where your mental health is truly at the forefront. My hope is that with each appointment—and each day—you feel supported in moving closer to the best version of yourself.

As a Nurse Practitioner, I believe healthcare should be a partnership, not a prescription. My approach combines advanced clinical skills with a deep commitment to patient advocacy, ensuring every individual has the tools and confidence to take charge of their health. I specialize in creating personalized treatment plans that honor the whole person — mind, body, and spirit. Whether I’m diagnosing, prescribing, or simply listening, my mission is to make every patient feel seen, heard, and cared for. I strive to turn sessions into moments of trust, learning, and hope."

I am board certified in Family Practice as well as Psychiatry and have been in practice for 25 year. I work with mental health issues such as depression, anxiety, sleep disorders, bipolar disorder, as well as address physical symptoms or issues that may affect mental health. I hold a Doctorate degree in education and Master Degrees in Advance Practice Nursing and education.

I'm Candice Jeffers, a board-certified Psychiatric Mental Health Nurse Practitioner with an unusual background—I spent nearly a decade in cardiovascular critical care before dedicating myself to mental health. That ICU experience taught me something crucial: psychiatric crises deserve the same urgency, expertise, and unwavering support as any cardiac emergency.

For nine years at Ascension Seton Medical Center's Cardiovascular ICU, I supervised teams through impossible situations. I learned to stay steady when everything felt uncertain, to read the subtle signs others might miss, and to offer hope when families needed it most. Those years shaped how I practice psychiatry today—with precision, presence, and profound respect for what you're facing.

I completed my Master of Science in Nursing at University of South Alabama in 2024, immersing myself in over 600 clinical hours spanning outpatient clinics, inpatient psychiatry, and crisis intervention. My pediatric nursing background adds another layer—I understand how early experiences shape us and how differently mental health shows up across ages.

My practice centers on thorough psychiatric evaluations, personalized medication management, and crisis intervention for all ages. I specialize in suicide risk assessment, trauma-informed approaches, and evidence-based treatments that actually fit into real lives. I'm MOUD-trained and licensed for telehealth in Texas, California, Arizona, and Florida.

Here's what matters most: I approach mental health as someone who's held space for both miracles and heartbreak. I know seeking help requires tremendous courage. I know healing rarely follows a straight line. And I know you need a provider who won't flinch, no matter what you share. My work blends critical care decisiveness with deep compassion—because you deserve both.

You don't have to arrive here put together. Whatever you're carrying right now belongs in this space: anxiety, grief, relationship stress, a shifting sense of who you are, or something you haven't quite found words for yet. I work with adults and older adults navigating the full range of what life brings, with a particular passion for supporting BIPOC and LGBTQIA+ communities and people who are questioning or deconstructing their faith. My work spans trauma, identity, women's issues, OCD, depression, and the anger or sadness that accumulates when you've been holding too much for too long.

Hello, I’m Elizabeth! I’m a board-certified Psychiatric-Mental Health Nurse Practitioner with over a decade of experience in mental health. I provide care in both English and Spanish. I enjoy helping people better understand their mental health and find treatment that works for them.
