Meet Dr. Kwame Frimpong, MD

Psychiatrist | Addiction Specialist | Physician Leader

With over a decade of medical experience, I bring a uniquely broad and deep understanding of both mental and physical health.

• Trained in Ghana across multiple specialties including surgery, internal medicine, pediatrics, and women’s health
• Psychiatry Residency at Harlem Hospital Center (affiliated with Columbia University, New York City)
• Chief Resident, leading clinical teams and mentoring physicians
• Addiction Psychiatry Fellowship at University of Texas Southwestern Medical Center (top program in Texas)
• Current Addiction Director at John Peter Smith (JPS) Hospital in Fort Worth

I work at the frontlines of psychiatry and addiction care—treating complex cases daily, teaching physicians, and delivering results-driven, compassionate care.

Patients describe me as calm, thoughtful, and genuinely invested in their success.

You should know that I truly care about who you are, not just the symptoms you’re experiencing. I understand that reaching out for mental health support can feel intimidating, especially if you’ve ever felt judged, misunderstood, or dismissed in the past. My goal is to create a space where you feel safe, heard, and respected from the very first conversation.

I approach every person with compassion, patience, and curiosity. I take the time to understand your story, your stressors, and what matters most to you, so your care is never one-size-fits-all. I believe healing happens best when you feel supported and involved in your treatment, and I see our work as a true partnership.

I am committed to using evidence-based practices while also honoring your lived experience. Whether we are focusing on medication, coping strategies, or long-term growth, I will always be honest, supportive, and collaborative.

Above all, you should know that you are not alone here, and your well-being is my priority.

My name is Siria Castro. I hold a Master of Science in Clinical Mental Health and am a Licensed Professional Counselor (LPC) and Licensed Chemical Dependency Counselor (LCDC). As a bilingual therapist fluent in English and Spanish, I provide comprehensive counseling services for adults, adolescents, and children, guiding clients through depression, anxiety, relationship challenges, family struggles, and more.

Getting here was the first step—now let's focus on where you want to go.

I’m a Licensed Professional Counselor (LPC) who is passionate about helping individuals navigate life's emotional and psychological challenges.

Whether you're experiencing anxiety, depression, stress, grief, trauma, relationship difficulties, irritability, sleep problems, or feeling overwhelmed by life's demands, I provide a supportive, nonjudgmental space where you can explore your experiences and work toward meaningful change.

I provide therapy in both English and Spanish and have experience working with adolescents, adults, couples, and families from diverse cultural backgrounds.
