Peconic Bay Medical Center’s Hospital Medicine Specialists deliver expertise along with personalized care.
Hospital Medicine Specialists are specialists in hospital medicine, which means they have a detailed knowledge of Peconic Bay Medical Center’s technological, diagnostic, and treatment resources to make sure patients receive the best care possible.
Often referred to as Hospitalists, they are highly trained, experienced medical professionals: Physicians, Physician Assistants, and Certified Nurse Practitioners.
A Hospital Medicine Specialist is not a doctor-in-training like an intern or resident. In fact, he or she is likely to also be a medical school professor or medical-practice educator who lends a hand in training new practitioners.
At Peconic Bay Medical Center, each patient is assigned a specific team of Hospital Medicine Specialists so there is always an experienced medical professional who is familiar with each patient’s clinical plan of care on duty 24 hours a day.
They improve our hospital’s quality of care.
Studies have shown that patients who are cared for by Hospital Medicine Specialists receive better care. They have better outcomes, are discharged sooner, and have fewer post-discharge problems or readmissions.
Call for more information about any of our clinical services or to schedule an appointment with one of our experts. Representatives are available on weekdays from 8am to 6pm and weekends from 9am to 5pm.

I was born and grew up in Ukraine. From my earliest childhood, it was my dream to become a physician, but it seemed an impossible dream. As a result of excellent grades in high school, I was accepted to the National Music Academy of Ukraine. At that time, it was impossible for me to enter medical school, so I was happy to accept the opportunity to gain musical knowledge. I earned a PhD in music, and after graduation I taught musical sciences in high school and played violin in the Opera House Orchestra.
But my dream of becoming a physician never died. Finally, I was accepted to one of the best medical academies in Siberia, and upon completion I was awarded a degree as Doctor of Medicine with honors, and I was recruited as a chief doctor in Obstetrics and Gynecology in that area.
When I came to the USA, I started all over again, and entered the NYIT College of Osteopathic Medicine. I chose Family Medicine as my specialty. After graduation and completion of a medical residency at PBMC, I started working as an attending physician here. I use music—playing piano and violin—for healing and recovery of my patients. This is my mission in life.
