Lauren Garrett, LMSW

Therapist & Mental Health Professional

IBH offers an integrated model that highlights collaboration between specialties which helps patients get to the root of their problem and heal. It is a model that is much needed in the mental and behavioral healthcare industry.”


Lauren comes to INPS by way of New York, California, and China.  A Licensed Master Social Worker, Lauren earned a BA in Communications from the University of Arkansas and a Master’s degree in Social Work from New York University. She has worked extensively with Psychodynamic and Cognitive Behavioral Therapy, serving primarily international and national adults in the university environment and high-risk youth in residential settings.  Lauren also worked with families of children with special needs in Shanghai, China while pursuing her graduate studies. 


One of INPS’ newer staff members, Lauren provides counseling, individual and family therapy and assists with the Neurofeedback Clinic. With her wide-ranging background in serving the mental-healthcare community, here is what Lauren had to tell us about coming to IBH:


“My experience serving diverse clients with a range of identity factors and mental health symptoms sets me up to contribute a great deal to INPS patients and team members.  I am excited to learn about and engage in the different roles related to neuropsychological services that INPS has to offer. I am learning more and more about the benefits of neurofeedback and the connection between brain health and mental health. I want my patients to understand that behavior is a function of what is occurring in their brain and that their behavior can reinforce the brain's response. The two are related, and the goal is to reach a psychological/physiological balance or homeostasis.”
