Find a therapist in Plainview, NY — covered by insurance

Hello , I am a therapist with over 30 years of experience working with teens and adults. I have worked in both inpatient and outpatient mental health settings. My priority is to create a therapeutic relationship in a safe, judgement free space.

As a clinical psychologist, I assist patients in reshaping negative thought and behavior patterns in a judgement free setting.

As a trauma therapist, I help people overcome terrible things that have happened to them in their lives. Abusive childhoods, violence in interpersonal relationships, rape, sexual assault, and cult survivors are my areas of focus. I help resolve the PTSD that often results from these atrocities, by using EMDR and traditional psychotherapy.

The common lie my clients tell themselves is, “It’s not that bad, other people have it worse.” You’re not other people. You’re allowed to get help.

I help college-bound teens and young adults work through repetitive thoughts of worry, insecurities, productivity pressure, people pleasing, loneliness and a range of other obstacles. In the therapy space, clients find their confidence so that they can build healthier relationships with family, friends, and partners. I specialize in working with disordered eating and body image concerns. My approach is warm, open, and straightforward.

Do you notice patterns of behaviors that you are unsatisfied with? Therapy is a significant step towards working through and facing life's most difficult challenges. I have worked with adults, adolescents and children treating issues of adjustment, self-doubt, mood swings, trauma and anxiety attacks. When you approach the therapeutic process with curiosity, you can grow, heal, and thrive.

Welcome!

Mental well-being is a top priority because it is the key that opens the door to a happy, healthy, and stable life. Life can be full of unpredictable circumstances and events that leave us feeling overwhelmed, frustrated, stressed, anxious, or depressed. Experiencing one, or all, of these starts to negatively impact critical areas such as sleep, work, self-motivation, personal relationships, or lead us to start engage in unhealthy outlets. It also makes us feel all alone and emotionally trapped. Reaching out for help can initially feel uneasy and it is a difficult task, but be proud of yourself that you are taking that first step! I have over 20 years of clinical experience working with clients aged 13 to 75 with a main focus on working for you, your needs, and how to achieve your goals to live a happy, healthy, and stable life. Specialty areas include anxiety disorders, depression, mood disorders, Acute and Post Traumatic Stress Disorder, relationships, couples/marital counseling, sexual issues, employees of law enforcement agencies, and forensic based testing.

Hi, I'm Jean-Jeffrey Marcellus, DNP, PMHNP-BC, AGNP-BC, a board-certified Psychiatric Mental Health Nurse Practitioner with over 19 years of healthcare experience. I provide compassionate, evidence-based care for adults experiencing ADHD, anxiety, depression, insomnia, and substance use disorders.

I specialize in Medication-Assisted Treatment (MAT) for alcohol, opioid, benzodiazepine, kratom, and prescription medication dependence. My approach is collaborative and personalized, focusing on creating treatment plans that support each individual's goals, recovery, and overall well-being.

I offer both in-person and telehealth appointments, providing a welcoming, judgment-free environment where patients feel heard, respected, and empowered. I am committed to delivering culturally responsive care and making high-quality mental health services accessible to individuals from diverse backgrounds.

I believe prioritizing mental health is key to stability in life. I know there is a better world out there and people need the tools to connect with their upmost insight for mental well being. In this field I am always eager to research and find healing processes to tailor the need of each individual.
