Hello, and welcome. My name is Darius Brittingham, and I am a mental health and substance abuse therapist with a Master’s degree in Rehabilitation Counseling. I am passionate about helping individuals navigate life’s challenges while building the skills needed to create meaningful and lasting change. My professional background includes working with individuals experiencing mental health concerns, substance use challenges, stress, anxiety, and life transitions. I strive to create a supportive, respectful, and non-judgmental environment where clients feel comfortable exploring their thoughts, emotions, and goals.

Clients who seek counseling may feel overwhelmed, stressed out, frustrated and anxious. My warm, compassionate demeanor coupled with a straightforward approach creates a supportive environment in which clients learn skills and receive guidance to become more engaged in their lives.

I also understand that the workplace can be rewarding, but also challenging, impacting a person’s happiness. Client’s leave therapy with coping strategies, helpful problem-solving abilities, and hope for the future.

I have been a practicing therapist for a decade and I have special interests and certifications in addiction and perinatal mental health. I received my masters degree from the George Washington University and have a perinatal specialist certification from Postpartum Support International.
