Training & Approach
Specialized Training
- •Institute for Functional Medicine — Root-cause medicine certification
- •University of Miami Miller School of Medicine — Advanced training
- •20+ years of clinical experience — Specialized in developmental disorders
The problem I solve: Many children in therapy aren't progressing as hoped because underlying clinical issues haven't been addressed. Therapists work hard, parents do everything right—but something is blocking progress.
My approach: I look for root causes—hidden infections, immune imbalances, gut-brain connections, nutritional deficiencies, toxic element exposure, or genetic factors—so the brain can become more receptive to therapy and learning. When we address these underlying issues, children become more regulated, attentive, and receptive.
What sets me apart: I combine the evidence-based rigor of my Institute for Functional Medicine training with a holistic approach addressing body, mind, and spirit. Being natively bilingual (English and Spanish), I can communicate directly with Latino families without barriers.

Heritage & Connection
As a Colombian by birth with lineage through Cuba, Portugal, Spain, and originally Sephardic Jews, I have a deep connection to the Hispanic community. I understand the cultural values, family dynamics, and unique perspectives that shape attitudes toward health and wellness in our community.
Speaking Spanish fluently allows me to communicate authentically with my clients, ensuring nothing is lost in translation when it comes to their health and wellbeing.

Ironman 140.6 Finisher
Completing the Ironman 140.6—2.4 mile swim, 112 mile bike, and 26.2 mile run—taught me about resilience, discipline, and the mind-body-spirit connection. I bring this same dedication to every family I serve.
