Dr-Sipkin-and-family

Jennifer Sipkin, D.D.S., P.C.

Dr-SipkinDr. Sipkin graduated from Columbia University College of Dental Medicine at the top of her class in 2004, and was immediately accepted into NYU’s prestigious orthodontic residency program. As a proud lifelong New Yorker, she considers it a privilege and an honor to have studied under some of the greatest orthodontists and craniofacial specialists New York has to offer. Loving academia, she has taught dental students at NYU and Columbia, and has performed and published research on numerous scientific topics ranging from craniofacial disorders to periodontal disease. Her most recent publication can be read in The Angle Orthodontist journal, and studies the efficacy of Invisalign® treatment on patients with periodontal disease. She has been featured on CBS news for her experience with Invisalign.

Dr. Sipkin prides herself on keeping her bustling office full of warmth and personal attention toward her patients, and enjoys treating both children and adults of all ages. She is a mom first, and the mommy instinct kicks into her decision making and treatment of all patients under her care.

“It’s a big responsibility…people are trusting you with their kids. I take that very seriously. I have very high standards for how I expect doctors to treat my girls, and I wouldn’t dream of giving less to my patients. And when the mom of a patient ends up asking me to do her Invisalign…that is always a personal highlight for me.  It means a lot to me when they are thrilled with their experience at my office.”

Dr. Sipkin has been president of her PTA, leads her school and neighbors in frequent community service fundraisers, and proudly serves on the board of Project Broadway in NYC to help bring an arts education to children in underserved communities. She is a mom to 2 beautiful daughters, and spends her free time taxiing them around to their various sports and arts activities. She stays active in the American Association of Orthodontists, and truly considers it a privilege to serve Valley Stream, Lynbrook, Oceanside, Rosedale, and surrounding communities each day, creating beautiful smiles for all!
