Hi, I'm Cassie (Cassandra), a board-certified Psychiatric Mental Health Nurse Practitioner with over five years of experience in mental health care.

Do you struggle with staying focused, feeling overwhelmed, managing anxiety, or keeping up with everyday responsibilities? Maybe you've spent years wondering whether ADHD could explain some of the challenges you're experiencing. My goal is to help you better understand what you're going through and find a treatment approach that works for you.

I specialize in treating adults experiencing ADHD, anxiety, depression, stress, burnout, and sleep difficulties. I particularly enjoy working with busy professionals, college students, and adults who feel stretched thin by their responsibilities.

My approach is warm, collaborative, and judgment-free. I take time to listen, understand your concerns, and develop an individualized treatment plan through comprehensive psychiatric evaluations and medication management.

I provide convenient telehealth appointments throughout California, making it easier to prioritize your mental health while balancing a busy schedule.

Whether you're seeking psychiatric care for the first time or looking for a fresh perspective, I'm here to help you find clarity, restore balance, and build confidence.

My approach to care begins with listening. I believe in creating a supportive, judgment-free environment where you feel heard, understood, and actively involved in your treatment.

Before our first appointment, you'll complete intake forms and questionnaires that help me understand your history, symptoms, and concerns. By reviewing these beforehand, we can spend less time gathering basic information and more time exploring your experiences in greater depth and focusing on what matters most to you.

I provide personalized, evidence-based psychiatric evaluations and medication management, incorporating supportive therapy, practical coping strategies, and lifestyle considerations when appropriate. Together, we'll develop a treatment plan that aligns with your individual needs and goals.

I also believe support shouldn't end when your appointment does. My patients have access to a secure messaging portal where they can reach out anytime with non-urgent questions or concerns. I personally respond to messages, typically within 24 hours.

My goal is to help you feel informed, supported, and confident as we work together toward lasting improvements in your mental health.

Important information before your first appointment:

I use Headway for insurance and billing purposes, but my practice uses a separate, secure patient portal for intake forms, appointments, and communication. After scheduling, you'll receive instructions to complete your intake paperwork before our first visit.

These forms allow me to review your history and concerns in advance so we can spend more of our appointment having meaningful conversations, exploring your experiences, and focusing on what matters most to you.

During our first session, we'll discuss your symptoms, concerns, personal history, and treatment goals in a comfortable, judgment-free environment. My approach is collaborative, and I want you to feel heard, understood, and involved in every decision.

If medication is appropriate, we'll review the potential benefits, risks, and alternatives together. I believe in thoughtful prescribing and will never pressure you into a treatment you're uncomfortable with.

My goal is for you to leave our first appointment feeling supported, informed, and confident about the next steps in your care.
