    My hugs to Liliana, Alonso and Holly! Judy will always be present in our minds, in our hearts and in our attitudes towards people with different abilities. I am very grateful to my dear “Mama”, who I had the honor of being able to affectionately call her. Judy leaves her legacy and we will continue to follow in her footsteps. Gracias Mama! Saudades!

    Un abrazo Liliana y Alonso. Recuerdo llegar al Sullivan hace 33 años con un diagnóstico incierto y mucho miedo. La dra Judith (así le decíamos ) siempre estaba observando, estudiando anotando mentalmente , dando pautas guía. Respeto, calidad de vida y esperanza eso fue lo que transmitió en mi. Honro su profundo compromiso con nuestros hijos y su fuerza para seguir adelante y siempre encontrar una Luz en el camino. Gracias Judith ! Tus enseñanzas fueron la base para educar no solo a mi hijo mayor sino a sus hermanos!!

    Meus sinceros sentimentos à família da Professora Judith.

    Fiquei conhecendo o Currículo funcional Natural no CASP Peru no Ann Sullivan com a Professora Liliana Mayo e sua equipe.
    Algo que acrescentou muito para a minha vida e para a minha prática pedagógica.
    Muito grata por conhecer essa obra que está beneficiando muito no Brasil.
    Forte abraço,

    Judy, you were an inspiring woman and I am grateful for the time I was able to spend with you. The legacy of caring service you leave behind will continue to improve the lives of so many. I aspire to be even a fraction of the woman you were.
