Dr. Lawrence Peacock, Chief Medical Officer

Dr. Peacock uses his story to illustrate the power of building a life that one is called to live. He grew up in a world that told him to "aim for less." It was sometimes said, but always known, that when you grow up poor and disadvantaged less is the best you'll ever be. However, he rejected that story.

His education on the human mind began as an individual pursuit. He spent many hours in his late teens and early twenties reading about psychology and the human experience. In his 20s, he decided to leave behind his job painting houses and began his pursuit of his undergraduate degree in psychology. He graduated from Rutgers University with highest honors. While at Rutgers, he was a Paul Robeson Scholar and he spent two years studying cognition. He continued on to Harvard Divinity School where he completed a Master’s Degree in Theological Studies. He completed his medical degree at the University of Vermont College of Medicine. He was privileged to complete his Adult Psychiatry Residency at Duke University where he served as the Chief Resident at the Durham VA Medical Center in North Carolina. While at Duke, he learned from the top faculty and leaders in the field. They taught him a sophisticated and nuanced approach to mental health and psychopharmacology.

After residency, he became the Director of ECT Services at UConn Health Center. While at UConn, he also served as the Medical Director of Outpatient Psychiatric Services. As a faculty member, he was heavily involved in their residency training where he introduced Positive Psychology to the UConn community with lectures and talks.

For several years, he was the Vice Chair of the Department of Psychiatry of Eastern Connecticut Health Network and the Medical Director of Inpatient Psychiatric Services at Rockville General Hospital in Vernon/Rockville, CT. Most recently, he served as The Director of Psychiatry at Wakulla Correctional Institution--a level 5 maximum security prison. 

He has received teaching awards at Duke and UConn and recently taught at the University of New England College of Medicine. Dr. Peacock has spent his life working to understand the human experience and how to help others to achieve what he refers to as “their best practice of self.” His interests range from the study of consciousness, religious experience to the biological predictors of human behavior from an evolutionary perspective.
