Hi there, I’m Oscar Oliver Baker, a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP) passionate about helping people feel more balanced, confident, and supported in their daily lives. I work with clients navigating anxiety, depression, ADHD, PTSD, trauma, stress, and burnout. I believe mental health care should feel collaborative, personalized, and judgment-free.

My approach combines thoughtful medication management with supportive therapy and practical coping strategies tailored to your goals and lifestyle. Whether you’re starting treatment for the first time or looking for a provider who truly listens, I strive to create a safe space where you feel comfortable and empowered in your care.

I want you to feel comfortable and understood from the very first conversation we have. My work centers on helping people manage anxiety, lift the weight of depression, and find steady footing in recovery from addiction. I see care as something we build together, not something done to you, so your voice shapes every step of the plan. Whether you are just starting to notice something feels off or you have carried a struggle for years, you deserve a partner who listens closely and treats your goals as the compass. I bring warmth, encouragement, and a genuine belief that change is possible, and I am glad you are here.

Hi, I’m Arelys! I’m a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with over 15 years of nursing experience. Throughout my career, I’ve had the privilege of caring for people from all walks of life, across different ages, cultures, backgrounds, and circumstances. Those experiences have shaped the way I approach mental health care: with curiosity, compassion, and an understanding that there is always more to a person than what brings them into the room.

I work with adolescents, college students, and adults experiencing anxiety, depression, ADHD, mood disorders, and the challenges and transitions that life can bring.

I chose to specialize in mental health because I believe meaningful care begins with truly getting to know the person in front of me. Your symptoms matter, but so do the experiences, relationships, stressors, strengths, and circumstances that shape them. I want our time together to be a space where you feel comfortable being honest, where your concerns are heard, and where you never feel like you have to fit into a one-size-fits-all approach.

My goal is to build a genuine, collaborative relationship and create a treatment plan that makes sense for you—one that supports not only symptom improvement, but your ability to feel more like yourself and move forward with confidence.

I am a board-certified psychiatrist committed to delivering compassionate, evidence-based, and person‐centered care to individuals experiencing a wide range of mental health challenges. My training includes a general psychiatry residency in New Jersey and an advanced Addiction Psychiatry/NIDA‐T32 Research Fellowship at Columbia University in New York City, where I received specialized experience in the treatment of substance use disorders, comorbidity, and academic research.

I am approachable and I like to provide a safe space.

Reaching out for support is one of the bravest things you can do — and I'm honored to be part of your journey. I work with individuals living with anxiety, chronic illness and pain, and substance use and addiction. I believe every person carries their own resilience, and my role is to help you access it. My practice is built on trust, warmth, and a deep commitment to your growth. I show up for my clients with honesty and the genuine conviction that meaningful change is always within reach

I am very dedicated to providing quality service to patients in my care and actively listening to their concerns

As your mental health provider here's what I want you to know about me:

• I listen first
• I believe in collaboration

• There is no shame in seeking help.
• Progress is possible.

Greetings & welcome. As a board certified Psychiatric Mental Health Nurse Practitioner, I offer brief therapy & medication management to adolescents & adults. Medication is not the best fit for everyone & together we can find your path.

What uniquely informs my psychiatric practice is my foundational background in pediatric neurology.
