MEET The TEAM

Andrew Pleener M.D., Psychiatrist
Dr. Pleener is a Board Certified Integrative Psychiatrist who believes that medications are just a “single” tool in an entire tool box to help heal. He works uniquely with each individual to uncover the root cause behind their symptoms while bringing forth a stronger understanding of mental health. Part of this process involves educating his clients on the impact that stress has on the nervous system, and how if left alone, can influence neurobiological outcomes such as hormonal imbalances, inflammatory changes, and various medical complications, resulting in disruptions of our natural bodily rhythms further impacting the way we think feel and function. Dr. Pleener aims to create a customized plan with each client to help re-wire the nervous system, restore rhythm and promote mental wellness and fitness. This often involves the use of various non medicative healing modalities such as breathing, yoga, nutrition, psychotherapy and meditation.

As her body was healing, it was simultaneously rejecting re-growth. The healing process lasted nearly two times longer than anticipated and resulted in countless hours in rehab facilities.
If she could take one positive thing away from this experience, it’s that it challenged her to constantly show up as the best version of herself day in and day out even when she didn’t want to.
Coming from a family of healthcare workers, Teresa has long been a student of what it takes to get healthy and stay healthy. Her thirst for knowledge on diet, exercise, sleep, and resiliency is insatiable.
