“A space to improve the dynamic of the couple”
About Diego
I am a psychologist specialising in couples therapy for more than 20 years. I have worked with many Costa Rican and American couples living in Costa Rica. I see people at Clínica Diego Vega in Grecia, and I also offer virtual sessions and an online relationship assessment. My research interests include problems of trust in romantic relationships and infidelity.
I hold a bachelor's degree in Psychology from the University of Costa Rica. At Colorado State University I completed a master's in Human Development and Family Studies, with an emphasis in family and couples therapy, and a PhD in Interdisciplinary Studies with an emphasis in clinical supervision. I am trained in the Gottman Method at Levels I and II, in EMDR and in emotion-focused therapy. From 2007 to 2018 I directed the School of Psychology at Universidad Latina de Costa Rica, and from 2018 to 2022 I directed its Research Area. I have also taught at Colorado State University and on Semester at Sea.
Couples therapy with me is a space for reflection and evaluation, so the couple can improve their dynamic. I try to rescue and improve the relationship. Sessions are usually joint and last about 50 minutes. I also work individually when that helps, including trauma work with EMDR and relaxation training with biofeedback.
How Diego works
Sessions are usually joint and last about 50 minutes. I give a lot of importance to defining the goals the couple wants to reach. Couples therapy is a space for reflection and evaluation, so we can improve the dynamic of the relationship.
I work with the Gottman Method. That method also guides the one-day relationship assessment: a couple interview, individual interviews, questionnaires, a report and a therapy plan. It is an option for couples who want or need to move quickly in recovering the relationship, in one four-hour session.
I am also trained in emotion-focused therapy and in EMDR. In individual work I use EMDR for psychological trauma, and I train relaxation with biofeedback.
Approaches
General information from Kyan about each method, not a description of how Diego works.
Gottman method
The Gottman method is an approach to couples therapy based on long-term research into what helps relationships last. It works on friendship, handling conflict and building shared meaning, often with practical exercises for the couple. Couples usually begin with an assessment of their relationship’s strengths and challenges.
Emotion-focused therapy (EFT)
Emotion-focused therapy (EFT) sees emotions as important guides that can be understood and changed. It helps you notice, name and work with feelings, including painful ones, so they become less overwhelming. It is also widely used with couples, to understand the emotional cycles between partners and build a closer bond.
EMDR
EMDR (Eye Movement Desensitisation and Reprocessing) is a structured method for working with distressing memories. While you briefly bring a memory to mind, the therapist guides you through bilateral stimulation such as eye movements or taps, which can help the memory feel less intense. It is best known for its use after traumatic experiences.
Relaxation techniques
Relaxation techniques, such as breathing exercises, progressive muscle relaxation and calming imagery, help the body and mind wind down. Practised regularly, they can lower tension and make stress, anxiety and sleep problems easier to manage. They are often taught as skills you can use on your own between sessions.
