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 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. Similar to concierge medicine practices, I also offer conveniences like same- or next-day appointments that start on time. 

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.

Testimonials from patients of Dr. DeRosa

from Suzanne in NJ March 15, 2024 for Joseph DeRosa, MD

Last summer I woke up one morning with tremendous pain in my left side making it very difficult to walk. Dr DeRosa and his staff kept in touch with me daily for several weeks as I sought out several specialists to determine the cause of this pain. As each specialist ruled out their suspected diagnosis Dr DeRosa and staff persisted in finding an answer. When he referred me to a pain specialist… See more

Words cannot describe my appreciation for Dr. Joseph DeRosa's ongoing commitment to my care, and the care of my son. There is never a time I reach out to him that I don't hear back within an hour, most often sooner. Amy and Lisa, his team, are also at the ready to assist whenever I need attention or help. Without Dr. DeRosa's care all of these years, I'd truly be a mess… See more
