Welcome to the practice of Mercedes Rizo M.D. specializing in individual therapy and psychopharmacology to enhance mental well-being.

About Dr. Rizo

I hail from Mexico City, where I completed my medical education at Universidad Autónoma de Mexico and an internship at Centro Medico Nacional. I furthered my medical career with a Fellowship in Hematology at George Washington Hospital and a Psychiatry Residency at St. Elizabeth’s Hospital in Washington, DC. I gained valuable experience working at the Santa Clara Mental Health System in Menlo Park, CA, and the Center for Special Problems in San Francisco, where I treated transgender patients, demonstrating my commitment to inclusive care. I also worked at the VA in Menlo Park, California, and at Sheppard Pratt Hospital in Towson, Maryland. In 2000, I established my private practice, where I continue to provide compassionate and comprehensive mental health services. My extensive education and diverse clinical experiences have made me a seasoned and experienced psychiatrist.

Approach to Therapy

I describe my approach as eclectic, incorporating psychodynamic, humanistic, and interpersonal therapies. I explore unconscious patterns from past experiences (psychodynamic), emphasize personal growth and self-fulfillment (humanistic), and improve relationships and communication (interpersonal). I tailor my methods to meet the unique needs of each patient, ensuring personalized and effective treatment.

Personal Life & Motivation

I am a proud mother of two grown daughters and grandmother to two wonderful grandchildren. Outside of my professional life, I enjoy gardening, reading, and spending time with my beloved pets. My passion for giving back to the community is evident in my volunteer work at a hospice, where I nurture a special interest in end-of-life care. My personal journey includes nine years of psychoanalysis, which profoundly shaped my belief in the practice of psychiatry. I find psychiatry fascinating and views becoming a doctor as a path to gaining a deep understanding of life and human beings.
