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

John and I are so pleased to be patients of Dr. DeRosa. As senior citizens, it is so reassuring to know that Dr, DeRosa is there for us 24/7 and that we are not just names and ID’s.

He is always available for appointments, to speak to, to text and to email. He is genuinely interested and concerned about our health and well-being.

Recently, Amy called to ask how we were. Dr.… See more

from Gloria in NJ June 11, 2020 for Joseph DeRosa, MD

Dr Joseph DeRosa has always gone above and beyond. The comfort this gives me is truly priceless especially for me and my personality.
His bedside manner and his knowledge is way beyond the norm of the Doctors and practices I have been to in the past. During the Covid 19 crisis he has sent emails everyday ( that I looked forward too) to explain and help us sort out what in the world was… See more

from G in NJ March 13, 2020 for Joseph DeRosa, MD

On a recent vacation to Bermuda I came down with a horrible sinus infection in the middle of our vacation. What was I going to do? Pay a lot out of pocket to see a doctor in a foreign country for a prescription? What to do- I emailed Dr. DeRosa a detailed message of my symptoms. At 7:00 in the morning on a Saturday I got his response: “Penicillin would be perfect!” “Find out if I can fax a… See more

from Michael in NJ March 3, 2020 for Joseph DeRosa, MD

We have have been patients of Dr. Joseph DeRosa for five years now. He has brought a focused attention to preventive medicine and improving our health that had been seriously lacking. When we are healthy, he helps us improve. When are ill or have concerns, he treats us with skill, care and compassion. Dr. DeRosa and his team are great.

from Steven July 22, 2019 for Joseph DeRosa, MD

I have a very thorough annual exam with Dr. DeRosa including EKG, Ultrasound, etc. The doctor is very good about communicating results in writing and with test results. I have these in my email inbox and they came in handy the other night. I was admitted to the hospital with chest pains and feared a heart issue (turned out to be GI-related). My EKG at the hospital was irregular and they… See more

from Maureen July 22, 2019 for Joseph DeRosa, MD

In an age when health care is on everyone's mind, my family and I are blessed to have an extraordinary doctor and man take care of us.While preventative medicine is his ultimate goal, he is equally concerned with the chronically ill. Dr. Derosa is brilliant; he diagnoses maladies long before the ologists have weighed in. In addition. his compassion, concern, and attention are unmatched… See more

from Paul May 5, 2019 for Joseph DeRosa, MD

I have been a patient of Dr Joseph DeRosa for close to 20 years, even before MDVIP. My 68 year medical history includes the last 54 years as a Type 1 Diabetic (minimal complications). With this background, I have had treatment by numerous doctors and specialist besides the typical Endocrinologist. General Practitioners and Internal Medicine professionals have their place, but through my… See more
