Joseph DeRosa, MD

My Philosophy and Approach to Wellness...

I have been a physician specializing in internal medicine and primary care for over 20 years. My approach to your care begins with creating and maintaining an environment of comfort, caring, trust and individualized service.

When my patients are at the office, they are the focus of my attention with no interruption, delay or time constraints. The commitment to your health and wellness cannot be rushed. My smaller, concierge-style practice affords my staff and me the time to provide advanced screenings and tests to help identify risk factors and diagnosis and treat issues as early and effectively as possible. We also can focus on planning, prevention and comprehensive coordination of your care. My affiliation with MDVIP has helped me to achieve and improve upon these goals and principles with particular emphasis on cardiac care, bone health, respiratory care, diabetes, fitness, nutrition and more.

Our new state-of-the-art building and facility were designed with overall patient comfort and care in mind. My two long-time nurses, Amy and Lisa, have established personal relationships with each patient, allowing for the highest level of attention and follow-up care.

Having grown up in Westfield, New Jersey, I am an active member of this close-knit community and am proud of my family’s interest and involvement within the community as well. Located in the heart of Westfield, my personalized healthcare practice serves many surrounding areas of Union County and beyond. I am on staff at Overlook Hospital in Summit.

In 2014, I successfully passed my third American Board of Internal Medicine exam. The completion of this rigorous exam underscores my desire as an internist to stay highly trained and abreast of the most current diagnostic and therapeutic modalities in the field of internal medicine.

Although I maintain a small and intimate practice, I am always interested in meeting potential patients who share the same goals for their health - forming a close partnership that promotes open communication, disease prevention, wellness planning and coordination of care between doctor, patient and specialists.
