The PsychoNeuroPlasticity (PNP) Center is dedicated to revolutionizing the way behavioral medicine is practiced. The integrated knowledge we employ supports our philosophy that patients experiencing brain-based disorders can be empowered to restore mental and physical well-being and can affect positive shifts in their healing processes.

The PNP Center was cofounded by Dr. Lawlis and Dr. Peavey in 2004 because of the importance of adding brain functioning to the assessment of behavioral, psychological and cognitive challenges. Dr. Lawlis retired from the PNP Center in 2022 and the PNP Center has continued under the capable leadership of Dr. Barbara Peavey.

Providing a "brain-basis" in the development of highly individualized treatment plans capable of improving human potential is a primary goal of the PNP Center. The complex territory that is each patient requires a multifaceted assessment from an integrated team dedicated to finding solutions and improving brain health. These medical, neurological, psychophysiological, and psychological portraits enable us to nourish meaningful changes in the treatment plans and lives of those who look to us for hope.
