About The Practice

CNS Medical Group, APMC is an independent psychiatric medical practice that offers a comprehensive and individualized approach to whole person health and wellness in a confidential private practice setting. Our patients include adolescentsadults and families with an emphasis on both medical management and psychotherapy. 

The practice was founded on the core values of providing a high level of personal dedication within the professional relationship and the belief that excellent patient care begins--first and foremost--with a relationship of trust. This relationship, combined with academic excellence and technical skill, provides the foundation for the highest level of care.

Additionally, he is a Fellow of the International College of Neuropsychopharmacology (CINP, Collegium Internationale Neuro-Psychopharmacologicum) in Scotland, United Kingdom--a presigious global organization dedicated to encourage and promote international scientific study, teaching and the application of neuropsychopharmacology. 

Dr. Kostalnick was born and raised in Avon, Ohio and Littleton, Colorado. Dr. Kostalnick attended Columbine High School in Littleton, Colorado and he moved to the San Francisco Bay Area in 1990, where he attended and graduated from Valley Christian High School.

He earned a Bachelor of Science degree from California Polytechnic State University, San Luis Obispo in Biological Sciences with an Individualized Concentration. He attended the University of California, Irvine, College of Medicine where he earned the degree Doctor of Medicine. His internship included training in Pediatrics, Internal Medicine, Neurology and Psychiatry at the University of California, Irvine. He attended residency training at the Department of Neuropsychiatry and Human Behavior where he received additional training and education in both psychopharmacology and psychotherapeutic practices under the direct supervision of internationally recognized leaders in both medicine and psychiatry.

Additionally, Dr. Kostalnick was honored to have additional training at the University of California, Davis in the department of Child and Adolescent Psychiatry. He also spent time training in the Medical Investigation of Neurodevelopmental Disorders Institute (MIND Institute)--A collaborative international research center focusing on education, clinical care and research at UC Davis that provides comprehensive evidence-based assessments of children with neurodevelopmental disorders, i.e., ADHD, Autism/ASD, Down syndrome, fragile X syndrome, chromosome 22q11.2 deletion syndrome. 

This educational background provides for a comprehensive and developmental view of the whole person--both adolescent and adult.

Dr. Kostalnick and his family enjoy traveling and "Dr. K" is known for his humor and disastrous backyard gardening projects. 

He is also widely recognized for his shameless endorsement of cinnamon roll and donut consumption, much to the dismay of his physician colleagues in primary care, endocrinology, and cardiology.
