Welcome, I'm glad you're here.

I’m Bechael S. Harris, MSN, APRN, PMHNP-BC, a board-certified psychiatric mental health nurse practitioner with over 27 years of nursing experience. I provide care for adults and older adults navigating challenges such as depression, anxiety, dementia, Alzheimer’s disease, and other mental health concerns.

Hi, I’m a Board-Certified Psychiatric Mental Health Nurse Practitioner with over 20 years of nursing experience. I provide thoughtful, personalized care for individuals dealing with anxiety, depression, ADHD, and other common mental health concerns. My approach is warm, respectful, and judgment-free — I believe real healing starts with feeling heard and understood. I work closely with each client to create a treatment plan that feels supportive, practical, and tailored to their unique needs.

I have been a licensed psychotherapist practicing for 38 years, mostly focusing on treating depression, anxiety disorders and stress management. I work a great deal with couples as well.

I am a Licensed Marriage and Family Therapist (LMFT) with a Master’s degree in Marital and Family Therapy from the University of San Diego. Since graduating in 2021, I have worked with adolescents, adults, and couples in community mental health and outpatient settings.

I became a therapist because I wanted to make a meaningful difference in people’s lives. I’m passionate about helping others better understand themselves, work through challenges, and become the best versions of themselves. I believe everyone deserves the opportunity to heal, grow, and create a life that feels fulfilling and authentic to them.

I have experience supporting clients navigating depression, anxiety, mood and personality disorders, neurodivergence, relationship difficulties, life transitions, and general life stress. I believe therapy should be a space where clients feel safe, supported, and genuinely heard.

My approach is collaborative and individualized, drawing from modalities including CBT, DBT, Narrative Therapy, and EMDR. I work alongside clients to better understand patterns, build coping skills, improve relationships, and create meaningful change aligned with their goals and values.

As an Asian American growing up overseas, I bring cultural considerations and my multicultural experiences into the therapy process.

You may have held doubts about talk therapy and perhaps are thinking therapy may not work at all for what you are dealing with. Psychotherapy like all science is continually changing. Both new and long held approaches to well-being are vast. I invite you to consider Brainspotting before you rule out therapy entirely. My role as a Brainspotting clinician is to offer you support, as you discover your innate capacity for positive self change. I specialize in trauma focused therapy, specializing in treating anxiety disorders. I focus on various forms of addiction, OCD, behavioral issues, depression, bi-polar and mood disorders.

I am a masters level trained Brainspotting clinician and a U.S. Army veteran. I believe in facilitating change in a supportive environment, following and observing your amazing capacity to heal from trauma in your therapeutic work. I work with veterans, first-responders, and other populations struggling with unresolved trauma and anxiety disorders.

Your unique circumstances are to be understood, honored respected and explored in a judgement free, supportive and caring environment. The issues that you bring into therapy remain entirely up to you. I will listen to your wants and needs; joining you on the journey towards your desired sense of well-being.

I offer a supportive, affirming space where clients can show up authentically. I guide individuals in rediscovering themselves and taking meaningful steps toward a more purposeful and aligned life.

Hello,

I am Dr. Jaeger and I welcome you to my practice. I look forward to sitting with you, hearing your story, and developing a plan to help you with your concerns and needs.

Hello, my name is Sherri Crespin, a board-certified Psychiatric Mental Health Nurse Practitioner passionate about providing integrated care for complex mental health challenges, including personality disorders, PTSD and trauma, substance use disorders, ADHD, depression, anxiety, panic disorders, mood disorders, and bipolar conditions. My practice recognizes these conditions are interconnected in ways requiring specialized understanding.

I chose these specializations because I understand how trauma influences personality development, how ADHD complicates substance use recovery, how symptoms emerge during extreme stress, and how these complex interactions require providers who see the complete picture. Whether you're in recovery while managing other conditions, dealing with personality patterns that developed as survival mechanisms, or navigating multiple diagnoses, I bring the expertise needed for comprehensive care.

My approach emphasizes evidence-based treatments and the healing power of being truly understood. I recognize that seeking help for stigmatized conditions like personality disorders takes tremendous courage, especially after negative experiences with providers. I create a therapeutic space where you can explore your experiences without judgment or shame.

You can expect a thorough assessment, personalized treatment planning, and consistent support throughout our work together. My goal is to help you build resilience, develop effective coping strategies, and thrive in your daily life.
