As a PMHNP-BC who specializes in autism, complex cases, OCD, personality disorders, PTSD/trauma, schizophrenia/psychosis disorders, and substance use, I've built my practice around understanding that every person's mental health journey is unique—especially when multiple conditions interact or when traditional approaches haven't worked.

I also provide comprehensive treatment for depression, anxiety, panic disorders, mood disorders, and bipolar disorder, always with an understanding that these conditions often overlap and influence each other in complex ways. What I want you to know is this: your experiences are valid, your struggles make sense in the context of your life, and there's no such thing as being "too much" for treatment.

Whether you're masking autistic traits, battling compulsive behaviors, managing intense emotions, processing trauma, questioning reality, or struggling with substances, I meet you exactly where you are without trying to force you into a predetermined mold. My approach combines evidence-based treatments with deep respect for your individual needs and experiences.

You deserve a provider who doesn't see complexity as a problem to solve, but as a roadmap to understanding how to best support your unique path to wellness.

My name is Dr. Lentz and I have been practicing in the mental health field for over 10 years. I strive to help those acquire skills to overcome challenging situations that are tailored to a person's specific need. I am a goal oriented therapist that works diligently to achieve goals that are identified by the individual and myself. Life is full of situations that do not always have clear and definitive answers, which is a process the therapeutic approach I utilize can assist with.

Welcome! I’m a dedicated Psychiatric Mental Health Nurse Practitioner (PMHNP), passionate about providing holistic, solution-oriented care to individuals of all ages. I earned my degree from the University of South Alabama, and my approach is rooted in compassion, active listening, and evidence-based treatment tailored to your unique needs.

I specialize in medication management and psychotherapy for a wide range of mental health conditions, including anxiety, depression, OCD, PTSD, bipolar disorder, ADHD, schizophrenia, and mood disorders. Whether you’re a child, young adult, or part of the older adult population, my goal is to create a safe, supportive space where healing and growth can thrive.

I believe in treating the whole person, not just symptoms. Together, we’ll develop a personalized plan to help you regain balance and move forward with confidence. I look forward to supporting you on your mental wellness journey!

My approach to mental health care centers entirely around you. True healing happens when trust, safety, and collaboration come together. Whether you are navigating severe depression, managing long-term anxiety, or recovering from trauma, my goal is to provide a premium, supportive environment where you feel heard and empowered to reclaim a stable, fulfilling life.

As a board-certified adult psychiatrist, I bring unique depth to my clinical practice. I earned both my MD and PhD from the Albert Einstein College of Medicine, grounding my approach to medication management in advanced scientific research and evidence-based medicine.

My leadership and clinical training within the University of Texas Health System—including roles as Chief Resident, Assistant Medical Director, and Assistant Professor—deeply shaped my view of mental health. Having cared for individuals across institutions like MD Anderson, Memorial Hermann, the Dunn Behavioral Sciences Center, and Maui Memorial Medical Center, I possess the outpatient and inpatient expertise required to manage complex clinical cases with complete confidence.

I provide convenient, high-quality telepsychiatry and virtual care for adults (ages 18 and older) actively located in Texas, California, Hawaii, and Alaska.

Primary Clinical Focus Areas:

• Mood Disorders: Advanced care for major depression, treatment-resistant depression, and bipolar disorder.
• Anxiety & Stress: Targeted strategies for generalized anxiety, panic disorder, and high-stress professional burnout.
• Trauma: Compassionate, evidence-based recovery and support for PTSD.

Above all, I believe in partnering with you as a collaborative ally. My practice is a safe, sophisticated space where clinical excellence is a given, and we work together to help you rediscover hope and transformation.

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.
