For me, it is vitally important to establish a close and respectful connection with the people I treat, as well as to provide a space where they feel safe to delve into their own process.
I have collaborated with ICEERS and BeckleyMed as a research assistant in studies involving Ayahuasca and have contributed to several scientific publications regarding the results of these studies.

I understand health in a holistic and profound way and believe in the potential of an integrative approach to illness and emotional distress that places the person at the center and includes all their dimensions: physical, emotional, and spiritual, with a respectful and humane perspective.
Throughout my personal and professional journey, altered states of consciousness as a therapeutic tool have played a very significant and transformative role. In this journey, I have trained in transpersonal psychotherapy and in supporting altered states of consciousness, delving into, among other therapeutic resources, dream integration and focusing.
Licensed Psychologist (Registration No.: M-35210), General Health Psychologist, and PhD in Pharmacology, specializing in the treatment of prolonged grief from a constructivist psychotherapy approach. Currently, I combine clinical practice with scientific research and teaching.
Over the past decade, my work has focused on studying the therapeutic potential of psychedelic substances in grief processes following the loss of a loved one, as well as their capacity to foster post-traumatic growth. Supporting these processes has allowed me to witness the extraordinary resilience of the human spirit and its ability to continuously learn.
I strongly believe in the importance of integrating the existential and relational dimensions within the therapeutic process to gain a broader perspective on the challenges we face in Western society and to promote connection with oneself, others, and the world.

Thanks to this, I was awarded the Trevarthern Award by the University of Edinburgh in 2019.
I have completed certified training in Acceptance and Commitment Therapy, which employs a functional and contextual view of mental health. I firmly believe that psychology should have an open perspective, investigating the cultural and social context as well as the individual.

I founded the Arizona Relationship Institute (AZRI), an integrative therapy center in the United States, to provide therapy to clients while also offering training and supervision to fellow therapists. I served as its owner and clinical director from 2013 to 2020 and continue to serve as Director of Psychedelic-Assisted Psychotherapy Training and Intensives. My contributions to relationship therapy and therapist training have been published in professional journals, and I present regularly at conferences including ASKP3, AASECT, ICEEFT, and Mindvalley University.
Through this work—supporting clients in their healing journeys and equipping other professionals with integrative skills—I developed Soul Surfing™—an integrative approach to psychedelic-assisted psychotherapy. I’ve also developed a corresponding online preparation program for clients and their therapists: Soul Surfing Psychedelics: Resiliently Riding the Waves of Life. This framework supports clients and therapists in effectively integrating psychedelic medicine with trauma-informed therapy models and holistic healing practices, thereby optimizing psychedelic-assisted psychotherapy (PAP) experiences and outcomes. Clínica Synaptica in Barcelona serves as the international base for this work.
My passion lies in curating and facilitating personalized psychedelic retreats tailored to each client’s intentions. These retreats integrate psychotherapy with breathwork, meditation, somatic practices, time in nature, and visits to historical and sacred sites.
I also offer PAP training retreats centered on experiential learning for practitioners. Rather than relying solely on lectures and academic study, Soul Surfing trainings guide participants through the very processes they will later facilitate for clients—learning through personal experience and live, supportive consultation to attune sensitively to individual needs.Look for my forthcoming book, co-authored with Danna Skoy—Ketamine Curious: How This Legal Psychedelic Medicine Can Transform Your Trauma into Healing & Growth—scheduled for release in Summer 2026.
