I am Stanley Okeyemi, the founder of Brighter Light Behavioral Health Services. I am currently licensed as a psychiatric mental health nurse practitioner (PMHNP) in Texas, Connecticut, Florida, Idaho, Iowa, Washington, North Carolina, Nebraska, Virginia and New York. I have been working in the mental health industry for 16 years, but licensed as a PMHNP for four years, with a vast amount of experience and affiliations with over 40 hospitals/clinics combined across the USA

I am a Licensed Professional Counselor with over 10 years of experience helping adults and adolescents manage ADHD, anxiety, depression, OCD, stress, life transitions, and substance-related concerns.

My approach is practical, collaborative, and goal-focused. I use evidence-based strategies, including CBT and exposure-based work, to help clients better understand their patterns, build coping skills, and make meaningful changes in daily life.

I believe therapy does not have to be reserved only for moments of crisis. It can be helpful for anyone who wants to manage stress more effectively, improve relationships, strengthen emotional control, or feel more confident in how they handle life’s demands.

Taking the first step toward therapy can be difficult, but you don’t have to do it alone. I am a Licensed Clinical Social Worker with more than 16 years of experience providing therapy to children, adolescents, and adults. Throughout my career, I have worked in community mental health and held leadership roles overseeing outpatient mental health programs.

I specialize in helping individuals navigate trauma, anxiety, depression, ADHD, infertility, women’s issues, and life transitions. I believe that while our experiences shape us, they do not have to define us. I am trained EMDR and Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) and tailor treatment to each person’s unique needs and goals.

I have been working in healthcare since 2007, working as a certified nursing assistant taking care of elderly patients in long term care facilities and home care. I later graduated as a Licensed Practical Nurse in 2008 and continued to work in long term care facilities caring for the elderly. I graduated as a Registered Nurse from Bridgeport Hospital School of Nursing and went on to taking care of patients ranging from young adults to geriatric with acute conditions, stable chronic conditions and complex medical conditions. In 2018, I graduated as a Nurse Practitioner and worked with patients post cardiac surgery, critically ill patient in the intensive care unit and a mix of neurology, neurosurgery, general surgery, vascular surgery and medically unstable psychiatric patients. After experiencing postpartum, with my extensive medical background, I decided to pursue a degree in Psychiatry to help more people goring through what I went through. I graduated with my PMHNP from Western Connecticut State University in 2025. Through my education, I was able to provide care for patients, both stable and acute, with depression, ADHD, PTSD, Anxiety, and mood disorders.

I am a psychiatric nurse practitioner with a broad background in sociology. In my approach to treatment, I explore how culture, gender, and identity intersect with personality and neurochemical imbalances to produce psychiatric symptoms that impede daily functioning and interpersonal activities. Together with my clients, we determine the best pharmacological interventions to provide relief of these symptoms. I offer psychiatric evaluations, medication management, assessment for post-traumatic stress disorder, Connecticut state registration for eligible clients for medical marijuana, and Suboxone treatment.

I work with adults (26 - 64 years old) to improve the quality of their lives through a collaborative process in which client and provider together devise treatment plans that combine medication and behavioral modification. I am especially interested in men's mental health, but I work with all adults regardless of their gender identity.

In a world that is increasingly busy and complex, life can be overwhelming for all of us at some point in our lives. We all need a variety of ways to decompress. For example, I like to go to a pickleball court as often as my body will allow, where I find activity, community, and friendship. It is at these times when we need to reach out for support. Don't feel you have to struggle alone. I invite you to reach out and make a connection.
