Greetings! I'm Dr. Jhonatan Marte. I'm an openly neurodivergent psychiatrist who cares deeply about providing neuroaffirming care.

I provide personalized therapeutic approaches to foster resilience and emotional growth in my clients. Through empathy, communication, and evidence-based interventions, I tend to create a safe space for individuals to process their experiences, build confidence and develop healthy coping mechanisms. I have experience working with individuals as young as 6 to 55 years of age.

I am a therapist specialized in working with children, adolescents and adults. I am skilled in helping individuals navigate through the emotional and psychological impacts of trauma. I help individuals gain their voices back. With my extensive experience in family therapy, I work to strengthen family dynamics and support healing within the home as well.

Therapeutically; I understand that certain circumstances or life events may have impacted you, however I believe your past shouldn’t control your future. “Just like history; your story continues”, meaning don’t let anything or anyone end your story for you. “In order to see progress, you have to trust the process and believe you will overcome these hurdles”.
