Dr. Yost takes a family approach to patient care. He realizes that each child and each family is unique, with individual concerns and circumstances. Dr. Yost brings over 35 years of experience, working with different children and adults in a variety of settings. He continues today, consulting to CP Rochester. As the psychologist for the Arc of Monroe County, Dr. Yost also works with adults with developmental disabilities. For families with older children, this is often helpful.

Dr. Yost is a board member and officer of the Genesee Valley Psychological Association. His evaluation skills are recognized nationally as one of four Gold Standard Neonatal Research Network evaluators, certifying quality evaluations in different research sites across the country. Dr. Yost has also trained evaluators for ongoing research in the Seychelles Islands. He is a member of the research teams for the Seychelles Child Development Study and the Neonatal Research Network.

Dr. Yost realizes that this can be a difficult time for parents; they are concerned about their child. There is much confusing and conflicting information available online, in the news and in the press. Dr. Yost takes both the care and the time to help parents obtain the information and resources to help their child grow.


Dr. Yost is the Psychologist/evaluator for URMC's participation in an NICHD long term follow-up study of extremely low birth weight (less than 1000g) babies, mostly due to extreme prematurity.

Dr. Yost is interested in cognitive patterns of children with autism spectrum disorders as evidenced in the Leiter International Performance Scale II, a test of nonverbal abilities.

He is currently involved in research on sleep patterns and/or disorders in both children and adults with developmental disabilities, as well as children adopted from foreign countries in a general pediatric practice. Preliminarily, these groups have a higher than average rate of sleep disruption which contributes to emotional and behavioral functioning in other areas of their lives as well as those around them.

Dr. Yost is part of the Seychelles Child Development Study, a long-term study examining the effects of methylmercury in ocean fish on children's development.
