About

Eating disorders, and everything that comes before a diagnosis.

I am María Laura Marranzini, a clinical psychologist. I consult in Santo Domingo, inside two medical practices.

Food is rarely the problem. It is where the problem shows.

So the work does not start with what someone eats or how much. It starts with what that behavior is solving, because while it is still solving something it does not let go.

I studied clinical psychology at UNIBE and graduated in 2020. That same year I joined CESIC as a co-therapist, and between 2021 and 2022 I trained specifically in eating disorders at Fundación Memorial, facilitating groups under supervision. I wanted to specialize properly, and for that I went to Spain.

I took the Master’s in Eating Disorders and Obesity at the European University of Madrid, with 300 hours of supervised clinical practicum across two national reference centers. One was the child and adolescent unit at Niño Jesús Children’s University Hospital, with inpatients who needed round-the-clock care. The other was Santa Cristina University Hospital, adults and chronic cases.

Part of my work there was preparing parents for the day their daughters left hospital. That marked me. And it left me with the conviction that holds up everything else, which is that what is gained in treatment is held or lost at home.

I returned to the Dominican Republic in 2023 and received my exequátur in February 2024. Since then I have consulted at MIITRAL, preventive cardiology, and since 2025 at the Centro de Gastroenterología Avanzada. Both brought me in as part of an effort to make interdisciplinary treatment include mental health as well.

Working inside a medical practice changes the work. The patient arrives with a diagnosis and a set of instructions, and what tends to be missing is not information. It is how to hold the change once they leave the consulting room.

What I treat

What people come with.

You do not need a diagnosis

You do not need a name for what is happening in order to come in.

  • Anxiety around food
  • Eating to settle what you feel
  • Body image, when dissatisfaction does not shift even as the body does
  • Suspecting something is forming and wanting to catch it early

Most common diagnoses

  • Anorexia nervosa
  • Bulimia nervosa
  • Binge eating disorder
  • Presentations that do not fit cleanly into any category, which in practice are most of them

Obesity and medical treatment

  • Psychological support alongside medical treatment
  • I do not work with weight targets, I work with your relationship with food
  • Psychological assessment and preparation before bariatric surgery
  • Support during GLP-1 treatment, such as semaglutide (Ozempic) or tirzepatide (Mounjaro)

The medication lowers appetite. It does not change what food was doing for you, and that stays waiting.

Families and the people around them

  • Parents, partners and caregivers, as part of treatment
  • Also when the person is not ready to consult yet

Approach

How I work.

Cognitive behavioral therapy
In practice, looking at which thought arrives before the behavior and what holds it in place afterward.
Psychological and psychometric assessment
When the picture needs precision and we need to know what we are working with.
Structured programs with defined measures
To know whether anything is shifting or whether the route has to change.
Groups and psychoeducation
Which is where I started.
Work with the family
Alongside the patient or separately, depending on the case.

I see people in English and Spanish. I do not prescribe or adjust medication, and I do not design meal plans.

Public engagement

Public activity.

If you want a consultation.

Appointments are arranged over WhatsApp. The first is an assessment, and if what you tell me does not warrant treatment with me, I say so there.
