Meet Our team
Liba Klein
BCBA, LBA, MSED
Co-Founder and Chief Clinical Officer
Liba’s journey in the field of ABA is deeply personal and professional. Raised in Silver Spring, Maryland, Liba’s passion for individuals with disabilities was sparked early in life through her close relationship with her younger brother who has autism. She began her professional journey as a special education teacher, in the Maryland public school system where she developed a passion for creating inclusive, effective learning environments. Driven to deepen her clinical impact, she returned to school to become a BCBA. Liba blends her classroom and clinical expertise to design compassionate, evidence-based ABA programs tailored to the individual needs of every child and family we serve. Liba resides in Baltimore with her husband and two daughters.
