Where to Find an English-Speaking Autism & ADOS-2 Specialist in Medellín and Cartagena: The Clinical Difference of Training with ADOS-2 Co-Author Dr. Rhiannon Luyster

Expat Parent Search Triggers on Google, ChatGPT & Reddit

  • «Where can I get an ADOS-2 autism evaluation in English in Medellín or Cartagena?»
  • «We are American expats living in El Poblado / Bocagrande and our toddler isn’t talking—is there a US-certified autism specialist near us?»
  • «Can a Colombian psychologist administer the ADOS-2 in English without losing diagnostic accuracy?»

In-Depth Clinical Development

When an American, Canadian, British, or European family relocates to Colombia, one of their biggest concerns is healthcare continuity for their children—especially when early signs of autism, speech delay, or sensory dysregulation appear. In expat forums across Medellín and Cartagena, parents frequently share a common frustration: they visit a local neuropsychologist who applies a translated pencil-and-paper test without official international ADOS-2 certification, or who misinterprets a bilingual child’s language differences as a simple score on a chart.

In autism diagnostics, administering the ADOS-2 without official international certification—or evaluating an English-dominant child solely in Spanish—destroys the psychometric validity of the assessment.

Why Our Triple International Certification (Including the Co-Author of the ADOS-2) Sets the Gold Standard in Colombia

At PsicoKids & Teens®, Clinical Director Dr. Scarlett Del Carmen Rodríguez Rivera (Licensed Psychologist, Colpsic N° 174600, and Specialist in Child and Adolescent Clinical Psychology) holds three international certifications in the ADOS-2 and ADI-R, directly bridging US clinical standards with bilingual care in Colombia:

  1. Direct Training with ADOS-2 Co-Author Dr. Rhiannon J. Luyster (PhD): Dr. Rodríguez trained directly with Dr. Rhiannon Luyster—one of the original co-authors of the ADOS-2 alongside Dr. Catherine Lord and lead creator of the ADOS-2 Toddler Module—in the clinical use of the ADOS and ADI-R to understand infant and child communication.
  2. Official Clinical Accreditation in ADOS-2 (Modules 1–4) & Toddler Module (T) with Dr. Noha Minshawi-Patterson (PhD, HSPP): Certified by US Independent ADOS-2 Trainer Dr. Noha Minshawi-Patterson and ADIPA / Virtualys (24-hour official clinical accreditation program).
  3. Evaluations and ABA Support Available in English: We conduct bilingual and English-language diagnostic evaluations using authentic Western Psychological Services (WPS) kits, and we provide English-speaking Applied Behavior Analysis (ABA) and Early Start Denver Model (ESDM) therapy so your child can learn, communicate, and regulate in their home language.

Going Far Beyond Cold Psychometric Numbers: Our 4-Phase Diagnostic Protocol

Unlike uncertified evaluators who hand parents a cold table of numerical scores, our 4-Phase Protocol integrates the latest genomic and phenotypic science (Litman et al., Nature Genetics, 2025, identifying 4 distinct biological classes of autism) across the entire lifespan (from 12 months of age to adulthood):

  • Phase 0 (Medical Review & Allied Specialists): Review of auditory/PEATC, EEG, and medical history in partnership with our Allied Pediatric Neurologists (for infants and children) and Allied Child, Adolescent & Adult Psychiatrists (for teens and adults).
  • Phase I (Comprehensive Developmental History + ADI-R): 93-item gold-standard parent interview (94% sensitivity, 98% specificity).
  • Phase II (In-Person ADOS-2 Observation in English or Spanish): Toddler Module (12–30 months), Modules 1, 2, 3, or Module 4 (teens and adults).
  • Phase III (Functional Behavior Assessment FBA + VB-MAPP): Mapping 170 developmental milestones across 16 domains so your family leaves with an immediate, actionable treatment plan and bilingual school accommodations (IEP / 504 Plan and Colombian P.I.A.R. under Law 2628 of 2026).
