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.

Hello! My name is Cathy Randolph and I am a Board-Certified Mental Health Nurse Practitioner. I developed my passion for mental health during my journey working with veterans in residential PTSD and Substance abuse programs. My specialties include, but are not limited to treating and managing PTSD, Substance abuse, ADD/ADHD, anxiety, depression, mood disorders, and adjustment disorder. I am also a Medicinal Marijuana clinician.

Mental health is nothing to "work on later" or neglect. This is the place you can be vulnerable, emotional and free of judgement. I prioritize clear, open communication to create a supportive, non-judgmental environment. I practice active listening and will give you opportunities to reflect on your experiences with you as an empathetic partner. If we’re working through something challenging, you can expect me to be calm and patient.

My name is Caitlin Clouse. Licensed Clinical Social Worker is just one of the many titles I carry. First and foremost I am a mom, wife and daughter. Through my own lived experiences—including an estranged relationship with a parent during childhood, as well as experiencing secure attachment within a strong and supportive family system—I witnessed firsthand the impact that difficult and unhealthy relationships can have on an individual’s emotional regulation and overall well-being. I also experienced how supportive relationships and co-regulation within a family system can foster resilience, confidence, and motivation.

These experiences is what led to my decision to attend Adelphi's MSW program. I have always had a passion to work with adolescents to help them feel understood and validated.

I began my career providing in-home support to children and families experiencing crisis. Through this work, I developed a strong foundation in supporting individuals and families through challenging circumstances and transitions. Through my practice in building positive relationships with adolescents, I have been able to assist them in organizing their thoughts and communicating them more effectively to their family and friends. I have been able to see first hand how treating them with dignity and respect allows them to grow their perspectives and become better listeners, which enhanced the family system as whole. No matter the current dynamics of one's family, we all come from one, which is why utilizing Structural Family Therapy and ACT has been helpful in my practice with not just families but individuals as well. Whether you're a parent, daughter, son, brother or sister, I'm here to help.
