Here, Dr. Berezny has built a busy and successful family oriented practice based upon health, wellness, and prevention. His practice continues to grow on account of the great results his patients experience and on their referrals of friends and loved ones who they wish to experience better health and wellness, naturally, through chiropractic care.

If you haven’t personally experienced the benefits of better health through chiropractic, you may call my office, our initial consultations are always free to answer your questions.  We would love to see you at one of our Health Talks.  If our office is not convenient for you and  you need a referral to a local chiropractor, you may visit to locate a convenient office. A world of better health awaits you!” – Dr. John J. Berezny

Kathy joined the staff of Berezny Chiropractic in September 2001. She is a New Jersey native. Prior to joining the team at Berezny Chiropractic, she was a hairstylist for 34 years. Ultimately, she was looking for a career change.

"I was a chiropractic patient before coming to work for Berezny Chiropractic. I live in Flanders with my husband Basil and my four children Caitlin, Ryan, Craig, Eric and my grandson Cody. We all live a healthier and happier life because of our regular chiropractic care. And I figured I wanted to be a part of Berezny Chiropractic, not just a patient."


Angie, a mother of three children - Amanda, and twins Alicia and Jilian -- was a hairstylist for 35 years prior to joining the Berezny Chiropractic team. As a hairstylist she spent the majority of her days standing working with clients. Over the years this led to having severe sciatica and shoulder pain.

"I came to Berezny Chiropractic and became a patient of Dr. John. Following Dr. John’s care plan I was not only relieved of my pain, but have also experienced other health benefits and have continued with regular chiropractic care for myself and my family. I joined the staff of Berezny Chiropractic in November 2003."
