Dr. Kendra Westerhaus

Position: PhD, Child Phychologist
Specialties: Behavioral Health
Locations: Pocatello Pediatrics
Languages: English

Dr. Kendra Westerhaus, earned her doctorate in clinical psychology in 2012 from Idaho State University and was licensed the following year. She specializes in providing therapy and assessments for children and adolescents. Prior to working for Health West, Kendra spent six years in private practice at a local mental health clinic.

Dr. Westerhaus chose the field of psychology because she enjoys helping people become the best versions of themselves that they can be. Because children are still malleable, that is where Kendra believes she can make the biggest difference. Dr. Westerhaus is a past president of the Idaho Psychological Association and is an active member of the American Psychological Association.

Dr. Westerhaus was born in State College, Pennsylvania, and attended undergraduate school in Cleveland before moving to Pocatello in 2005 to work on a Ph.D. in clinical psychology at ISU. She has traveled extensively, including throughout the United States and Europe. She also visited Thailand a few years ago, where she took classes on Thai cooking. In her spare time, Dr. Westerhaus enjoys spending time with her family, singing in a community choir, crafts, and enjoying Idaho’s great outdoors

Dr. Greg Kostur

Position: MD, Pediatrician
Specialties: Pediatrics
Locations: American Falls, Pocatello
Languages: English, Spanish

Dr. Greg Kostur, Pediatrician was born in Buffalo, New York, and grew up in Florence, South Carolina and Charlotte, North Carolina. He graduated from The Citadel in Charleston, South Carolina with a B.S. in Biology in 1995. He then attended the Uniformed Services University of the Health Sciences in Bethesda, Maryland and graduated with his M.D. in 1999. He completed a Pediatrics Residency at Keesler Air Force Base in Biloxi, Mississippi in 2002.

He served in the United States Air Force until 2009 as a Pediatrician at Lackland Air Force Base in San Antonio, Texas, and Keesler Air Force Base. He has been a PALS and NRP instructor. He received the Air Force Meritorious Service Medal and was also awarded Medical Student Teacher of the Year for Pediatrics in 2006. He worked as a pediatrician in La Grange, Texas and San Antonio, Texas until 2019 before moving to Pocatello, Idaho in March of 2019. He left San Antonio because it was “too hot.”

Dr. Kostur has several hobbies but is always looking for new activities to experience. Currently, hiking, snowshoeing, backpacking, alpine and cross-country skiing are his favorite activities. He is also planning on embarking on a long-distance backpacking trip of over a hundred miles within the next couple of years. He enjoys classical music and is endeavoring to become a cellist in the Idaho State Civic Symphony in Pocatello. He enjoys cold weather, especially if it makes his “nose hairs freeze!” With that in mind, he also plans to try ice fishing, snowmobiling, ice climbing, and winter camping.

His outlook on children is holistic, encompassing the social, psychological, genetic, and physical components of their health. He aims to treat the “whole” child. As such, he is pleased to be part of Health West because it offers integrated behavioral health in its clinics. The Health West Pediatrics clinic includes a child psychologist and other behavioral health providers in the same clinic. His interest in early literacy led to the Health West Pediatrics clinic starting a “Reach Out and Read” clinical site, where all children under 6 years of age get a free book at every well child check.
