About Me
I am a trained Counseling Psychotherapist and Life Coach with 20 years of experience. I earned a Bachelor´s Degree in Clinical Psychology from SJSU (California) and Master’s Degree in Counseling Psychology from Santa Clara University in 2000. In addition, I count with extesive training in Coaching.
During my training in California, I specialized in mental health issues (such as psychotic, mood, adjustment, anxiety, impulse control and personality disorders), and carried scientific research  in the area of multicultural counseling, as I actively advocated for health issues among minorities and immigrants. Recognizing the importance of family and culture, I completed training on systemic approaches as well as coaching clients (and their families) on communication, parenting and interpersonal skills.

Upon completing my training, I moved back to Spain in 2001 where I licensed as Clinical Psychologist.   For a period of ten years, I specialized in substance abuse issues and Dual Diagnosis, serving as clinician and supervisor of several programs (Ultra-Rapid Opioid Detoxification, Multidisciplinary Relapse Prevention). I have helped hundreds of people in their efforts to overcome addiction to a wide range of substances, including alcohol, cannabis, opioids, benzodiazepines, and cocaine and other stimulants. I have mentored and supervised many psychology interns, provided professional lectures in several universities and professional symposiums, and have appeared on TV and radio programs.

In more recent years, I established my own private practice to further assist clients, and expand my own learning process. One of my latest achievements was to develop and implement a Comprehensive Counseling Program within a Neonatology Department serving parents and caregivers of extremely premature (+24 weeks) and very ill newborns. This pioneer counseling program in Spain, assisted many couples through this arduous and painful process, including, often times, the loss of stillbirth or death of a baby.

Lastly, five years ago I migrated back to Miami with my family, one more adventure, to grant my own children the same opportunities I have enjoyed living abroad and experience the rich diversity and possibilities that Miami has to offer. Currently, I am licensed to practice in the State of Florida and combine my work as Clinical Psychotherapist at Florida International University (FIU), and in private practice. 


  1. I had the pleasure to work with Guillermo at Gardner Family Care Corporation. Guillermo is a skilled mental health clinician with many years of experience working with high risk families. He provided excellent cultural competent mental health services to underserved individuals and their families. Guillermo brought to his work his own personal experience as an immigrant to the United States. His bilingual and bicultural skills were also invaluable. Guillermo is very professional, dedicated, accountable, a team player and well liked by others. Guillermo demonstrated professionalism and strong leadership skills. During the time I worked with Guillermo, he was highly respected by his peers and the administrators.

  2. Guillermo was a valued Supervisor. He was always available to assist patients with their mental health needs, and went out of his way to research any conditions that would help him treat our patient population. What amazed me the most was how some patients at first resisted the idea of psychotherapy, but then we're very sad to see him leave! He is missed.

  3. I had the fortune to meet Guillermo at Care Resource (CR) in 2013 and we worked closely together as the two managers in charge of Prevention programs involving HIV testing, outreach, and behavioral interventions. Guillermo is a very approachable, realistic, goal-driven, persistent, and ethical leader. His communication style is direct, efficient, non-judgmental, and people (clients as well as coworkers) felt comfortable going to him for guidance which quickly made him a very popular and busy man within his initial couple of months at CR. Guillermo is a team player who always volunteers his help even when not requested. He is patient, intelligent, with a natural ability to adapt to changing environments and shifting priorities. I fully recommend him not only as an accomplished professional in the psychosocial field, but also as a man with great morals and a big heart!
