The analyst behind Amethyst

Mara Karla Sánchez Pérez, M.S., BCBA, IBA · Founder
Mara Karla Sánchez Pérez, M.S., BCBA, IBA, is a bilingual behavior analyst, educator, and doctoral candidate. She built Amethyst Therapy Services on a conviction most prep courses avoid saying out loud: failing an exam is behavior — and behavior has a function you can assess, measure, and change.
“Well-designed systems create better outcomes than individual effort alone.”

Ethical boundaries and accountability
Practical implementation over theory alone
Cultural responsiveness without sacrificing rigor
Why Amethyst?
The method has three verbs
Observe. Analyze. Transform. It runs through everything here: the BILP™ assessment observes, the Peak Protocol™ analyzes, and your data — not a generic syllabus — decides what transforms. It's the same discipline we bring to a clinical case, applied to your certification.
Two languages, one standard
Nothing here is translated after the fact. Every class, template, and letter is written natively in Spanish and in English — because your certification exam won't lower the bar for your second language, and neither do we.
Outcome-Focused
Measurable progress, reinforcement-based teaching, and caregiver empowerment drive our approach.
Collaboration-First
We work alongside families, professionals, and providers to build systems that fit real life.
