Mary Marasovich, M.A./CCC/SLP

Jack_Russell_Puppy_Eddi   Graduated from California State University, Stanislaus with a masters in speech pathology and a special education credential. I brought my experience in the public schools, hospitals, private practice and home health with me to Hawaii in 1986. Some of my specialized training includes PROMPT (Prompts for Restructuring Oral Muscular Phonetic Targets), the Lidcombe Stuttering Program, Lindamood/Bell Visualizing and Verbalizing, SpeechEasy anti-stuttering device dispenser, various accent modification programs, and continuing education in many areas. Over time I have developed many special interests which currently include Autism related disorders, Auditory Processing, Apraxia, Cleft Palate and Stuttering. I believe in patient driven treatment with family involvement and use approaches that fit the individual. I have a passion for all things speech related and contribute to the future of my field by training master's level interns and clinical fellows from all over the world. In January of 2015,  I completed a Clinical Supervision CEU course to sharpen my skills.   I served for many years on the Queen's Cranio Facial Board and provided video voice studies at Straub Hospital. While I enjoy my reputation as a workaholic, I do take advantage of living in this healing and magic place by kayaking, paddle boarding, walking and sailing with my husband and our dog, Mochi. While my profession is a joy, I am most proud of raising my 3 children to be wonderful adults and know that parenting has given me a compassion and caring for the parents and children who come to our clinic for answers.
