A Note from Northport Wellness Center Pediatrician, Dr. Palevsky:

Dear Patients and Friends,

Please join me in welcoming Jennifer Zethner, RN, MS, PNP, to the practice of Holistic Child Health at the Northport Wellness Center. During my leave of absence, Jennie will see patients one day a week. As time goes on, she looks forward to increasing her hours to accommodate your needs.

As a Pediatric Nurse Practitioner working in the practice of Holistic Child Health at the Northport Wellness Center, Jennie is licensed and trained to see your children for regular pediatric visits. She will be able to take their medical histories, perform regular pediatric physical exams, especially to fill out camp and school forms, and prescribe medical treatment programs as needed. For those families who have brought their children to see me for ongoing medical issues, Jennie will also be able to follow your children’s progress in the Northport Office.

Jennie will continue to support and carry on the holistic philosophy that I have brought to the practice, and will also bring her own brand of holistic medicine to the office. Parents will be able to contact her at This e-mail address is being protected from spambots. You need JavaScript enabled to view it. . Please call the Northport Wellness Center at 631-262-8505 to make an appointment to see her.

While I am on my leave of absence, I will be serving as Jennie’s supervising physician. Jennie and I will be in frequent contact about your children’s medical care, especially where it becomes necessary for me to offer additional medical advice. We will work as a team to continue to bring you the type of holistic medical care that you seek for your family. I feel very positive about the experience you will have seeing Jennie in the office.

Take good care.

Lawrence B Palevsky, MD
