Georgia Barnes, MSN, FNP-C, PMHNP-BC

I am a dual board-certified Advanced Practice Registered Nurse (APRN) with more than 25 years of clinical experience and board certifications as both a Family Nurse Practitioner and Psychiatric Mental Health Nurse Practitioner. I provide compassionate, evidence-based mental health care for adolescents and adults experiencing anxiety, depression, PTSD, ADHD, mood disorders, and other psychiatric conditions through personalized medication management and supportive psychotherapy.

I believe meaningful mental health care begins with trust, respect, and collaboration. My approach is patient-centered, recognizing that every individual's experiences, strengths, and goals are unique. I work closely with each client to develop a personalized treatment plan that promotes emotional wellness, resilience, and long-term recovery.

My priority is to create a safe, welcoming, and nonjudgmental environment where you feel heard, valued, and empowered to participate in your care. Together, we focus not only on reducing symptoms but also on building healthy coping strategies, restoring balance, and improving overall quality of life. Whether you're facing anxiety, depression, trauma, mood disorders, ADHD, or co-occurring substance use concerns, I am committed to providing thoughtful, evidence-based care that supports your journey toward lasting wellness.

Feeling depressed, anxious, overwhelmed, or heartbroken? Life can be challenging, and sometimes we all need support. I'd be honored to help you walk through your difficult situations and emotions. With several years of experience helping people from all walks of life, I take a non-judgmental approach tailored to your unique circumstances, helping you heal, solve problems, manage challenges, and grow into the person you want to be.

I am a Licensed Clinical Social Worker (LCSW) in California and a Licensed Independent Clinical Social Worker (LICSW) in Washington, DC. I provide psychotherapy to adults navigating anxiety, depression, trauma, relationship challenges, and life transitions.

I currently work with the Integrative Digestive Health team at UCLA Health and also provide therapy through Lyra Health. I bring extensive experience across medical and mental health settings, including six years as a liver transplant social worker at Cedars-Sinai Medical Center, work on the first COVID unit at George Washington University Hospital, and leadership roles in community mental health organizations in Washington, DC.

My approach is warm, collaborative, and client-centered, grounded in trauma-informed care. I primarily use cognitive behavioral and solution-focused therapies while tailoring treatment to each individual. I have particular expertise in trauma, the intersection of physical and mental health, and interpersonal relationships. I offer both short- and long-term therapy and believe meaningful change happens in a space that feels safe, supportive, and authentic.

I am happy to provide a free 15-minute consultation (upon request) to ensure a good fit. To request a consultation, please email: [email protected].

Outside of work, I enjoy traveling, hiking in the Los Angeles mountains, kayaking, and spending time with my rescue dog, Sophia.

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.
