Your life has purpose despite any painful experiences that you may have faced. I believe hurtful experiences can be turned into a message of hope. I also believe that it is possible to not just survive unexpected, generational, and traumatic experiences in life, but to thrive fully in life.

It was not always easy for me to ask for help, even in my personal life, but I learned the value in doing so. Therefore, I will value walking alongside you through your journey. There will be no judgment when you work with me, only respect and a commitment to creating a path toward healing.

I am an experienced provider who has devoted my education and career to assisting and advancing the needs of children, adolescents, and their families. While my specialty is working with children and adolescents, I also enjoy providing psychological therapy for young adults. I have extensive experience helping individuals navigate depression, anxiety, trauma, life transitions, identity development, self-esteem concerns, and relationship challenges. In addition, I have collaborated with psychiatrists, advanced nurse practitioners, physicians, behavioral specialists, various government child service agencies, and other professionals to ensure comprehensive care for clients and their families.

I believe it is vital to create not only a safe space, but also a welcoming space that nurtures healing. I provide individual and family-based sessions that promote emotional and social growth through enhancing problem-solving techniques, coping strategies, and interpersonal skill development. I implement evidence-based treatment and tailor my approach to meet each person's unique needs. I am also able to provide play-based interventions and expressive arts interventions to support emotional expression and self-exploration in a way that fits each individual's age and stage of development.  In addition to conducting research focused on adolescents, I have gained experience across a range of settings, including a behavioral health hospital, therapeutic day school, hospital-affiliated community mental health organization, and a mental health nonprofit organization. 

My therapeutic approach emphasizes client advocacy through a collaborative and client-centered approach to care. I believe it is critical for clients to be active participants in treatment and to have space to explore their experiences, questions, and concerns. This helps to foster a more holistic understanding of each person's needs while supporting meaningful growth and healing.

My educational background includes a Doctorate in Clinical Psychology with an additional specialized concentration in Child and Adolescent Psychology from Midwestern University in Downers Grove, Illinois. I am also trained in Trauma-Focused Cognitive Behavioral Therapy (TF-CBT), with a national certification nearing completion. I earned a Master of Arts in Clinical Psychology and a Bachelor of Science in Psychology with a Minor in Counseling, graduating Summa Cum Laude. These experiences continue to shape my commitment to providing evidence-based, developmentally appropriate, and compassionate care.

I look forward to hearing from you.

Whether you are seeking therapy for the first time, returning after time away, or looking for a therapist who feels like the right fit, I am here to support you. Life can bring challenges that impact your emotional well-being, relationships, sense of self, and ability to cope with daily stressors. My goal is to provide a compassionate and welcoming environment where you can openly share your experiences, gain deeper self-understanding, and move toward the life you want to create. You do not have to navigate these challenges alone, and together we can work toward meaningful growth and lasting change.

I have experience working with both adolescents and adults navigating concerns such as anxiety, depression, trauma, substance use, stress management, relationship conflicts, and life transitions. Many of my clients come to therapy feeling overwhelmed by responsibilities, struggling to manage difficult emotions, experiencing challenges in their relationships, or carrying the impact of past experiences. These concerns often affect not only how we feel emotionally, but also how we connect with others and navigate daily life.

My approach to therapy is collaborative, client-centered, and tailored to your unique needs, strengths, values, and goals. By integrating Cognitive Behavioral Therapy (CBT) with a person-centered framework, I help clients gain insight into the connections between their thoughts, emotions, and behaviors while feeling supported and empowered throughout the therapeutic process. I also integrate other therapeutic modalities in our work together Together, we will examine the thoughts, emotions, and experiences that shape your well-being and identify strategies to help you build resilience and move toward your goals.

I believe that meaningful change occurs when individuals feel safe, accepted, and equipped with practical tools to navigate life's difficulties. I strive to understand the whole person, not just the symptoms you may be experiencing, and believe that each individual is the expert on their own life. My role is to provide guidance, support, and evidence-based strategies that help you create lasting change and a more fulfilling life.

Dr. Riley Christoph is a Licensed Psychologist in Texas who specializes in providing integrative, individual therapy for adolescents and young adults. She helps young people navigate anxiety, depression, ADHD, trauma, self-esteem concerns, emotional challenges, and major life transitions while fostering resilience, confidence, and meaningful growth. 

At the heart of Dr. Christoph's work is the belief that a strong therapeutic relationship serves as the foundation for lasting change. She creates a supportive, nonjudgmental environment where clients feel understood, valued, and empowered to explore their experiences. Viewing each individual as far more than a diagnosis, she tailors treatment to each client's unique strengths, needs, and goals. When working with teens, she takes a collaborative, family-centered approach, partnering with parents, caregivers, and educators to support growth across all areas of a young person's life. 

Rather than relying on a one-size-fits-all approach, Dr. Christoph integrates evidence-based therapies—including Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), Acceptance and Commitment Therapy (ACT), Motivational Interviewing, Solution-Focused Therapy, and expressive arts techniques—to meet each client where they are and help them build practical tools for everyday challenges. 

Her professional experience includes developing innovative mental health programming within a college preparatory high school, participating in youth-focused research initiatives, and providing care across community mental health and dual-diagnosis settings. This diverse background allows her to offer a thoughtful, down-to-earth approach that helps young people better understand themselves, build on their strengths, and navigate life's challenges with greater confidence. 

Every young person deserves a space where they feel heard, understood, and empowered to grow. Dr. Christoph works collaboratively with teens, young adults, and their families to foster resilience, strengthen coping skills, and support lasting emotional well-being.

Many people come to therapy feeling overwhelmed by emotions, complicated relationships, or cultural pressures; it’s okay to need support. As a South American woman raised in New York City, I understand how identity, culture, and lived experiences shape our emotional world.

My style is warm, supportive, and focused on building connection. I draw on a wide range of evidence-based therapeutic approaches to create personalized plans that fit your unique needs, helping you navigate life’s challenges and foster meaningful growth. To learn more about the comprehensive treatments offered at Nowlogy, visit our Treatments Page. I believe in working with your strengths and creating a space where you can make sense of whatever you’re carrying, whether it’s stress, complex emotions, or challenges tied to identity and culture. I especially care about supporting folks from diverse racial/ethnic and sexual backgrounds, as well as Spanish-speaking communities, who often navigate unique experiences.

Whether you’re seeking healing, clarity, practical skills, or simply a space where you can feel seen and supported, I offer a relaxed, inclusive, and collaborative environment where you don’t have to go through it alone. Therapy doesn’t have to feel intimidating; it can be a conversation rooted in care and connection. I’m fluent in Spanish and have experience working across diverse settings and cultures. If you’re wondering whether this space might be right for you, I invite you to reach out for a consultation—no pressure, just a chance to see if we’re a good fit.

On my free time, I enjoy being outdoors and soaking in the sun with my little boy. I like watching documentaries and listening to Latin music. I also enjoy trying artistic activities, even if I may not have the talent for them!

Muchas personas llegan a terapia sintiéndose abrumadas por sus emociones, relaciones complicadas o presiones culturales; está bien necesitar apoyo. Como mujer sudamericana criada en Nueva York, entiendo cómo la identidad, la cultura y las experiencias de vida influyen en nuestro mundo emocional.

Mi estilo es cálido, acogedor y enfocado en crear una conexión genuina. Utilizo una amplia gama de enfoques terapéuticos basados en evidencia para crear planes personalizados que se adapten a tus necesidades únicas, ayudándote a navegar los desafíos de la vida y a fomentar un crecimiento significativo. Para obtener más información sobre los tratamientos integrales ofrecidos en Nowlogy, visita nuestra Página de Tratamientos. Creo en trabajar desde tus fortalezas y en crear un espacio donde puedas darle sentido a lo que estés cargando, ya sea estrés, emociones complejas o desafíos relacionados con la identidad y la cultura. Me importa especialmente apoyar a personas de diversos orígenes raciales/étnicos, de género y sexuales, así como a comunidades de habla hispana, que a menudo enfrentan experiencias únicas.

Ya sea que estés buscando sanar, obtener claridad, aprender herramientas prácticas o simplemente contar con un espacio donde te sientas visto/a y acompañado/a, ofrezco un ambiente relajado, inclusivo y colaborativo donde no tienes que atravesar todo esto solo/a. La terapia no tiene que ser intimidante; puede ser una conversación basada en el cuidado y la conexión. Hablo español con fluidez y tengo experiencia trabajando en entornos y con comunidades culturalmente diversas. Si tienes curiosidad por saber si este espacio es el adecuado para ti, te invito a una consulta—sin presión, solo una oportunidad para ver si hacemos buen equipo.

En mi tiempo libre, disfruto estar al aire libre y tomar el sol con mi hijo pequeño. Me encanta ver documentales y escuchar música latina. También me gusta probar actividades artísticas, aunque no siempre tenga el talento para ellas!
