Albert Heffez, DDS & Jennifer Lombardo, DDS

When Jennifer Lombardo DDS and Albert Heffez DDS first connected at New York University -School of Dentistry, they knew that they shared a passion for enhancing oral health. What they didn’t know then was how that connection would grow into a marriage, a family, and the thriving dental practice of Windsor Dentistry.

After completing their undergraduate degrees, hers in Biology at SUNY Stonybrook , and his in Psychology at NYU, both doctors completed dental school and moved onto their residencies. Dr. Lombardo served as a resident in General Dentistry at Lutheran Medical Center. At the same time, Dr. Heffez served as Chief Resident in Dental Surgery at Brookdale Hospital Medical Center.
While residency and countless hours of continuing education afforded both doctors the opportunity to develop their clinical skills, they dreamed of a way to help patients more personally, with a focus on preventive care and overall wellness. With those values in mind, Windsor Dentistry began.

Today it’s a family focused practice where people of all ages can get the dental care they need, compassionately and with consideration for their lifestyle and whole-body health. Most patients see both Dr. Lombardo and Dr. Heffez at some point during their years of care, since they each have advanced training in specific areas, making Windsor Dentistry a dental home for patients with varying needs.

Dr. Lombardo focuses on Preventive Dentistry, Minimally Invasive Restorative Dentistry, Cavity Control, Cosmetic Dentistry including Veneers, Invisalign and Dentures.

Dr.Heffez focuses on Implants, Sleep Apnea Therapy, TMJ Therapy, Cosmetic Dentistry, Veneers and Full Mouth Reconstruction. Both doctors work together to maintain a friendly, proactive practice focused on building relationships and elevating overall health. 

Since their days at NYU, they’ve grown together to have many other common interests: two daughters, a dog Otis, renovating their neighborhood home. But it’s still the drive to help others on their journey to achieve optimal health that ties them together.

One patient, one mouth, one healthy smile at a time, they’ve built a practice that’s one of the best in Brooklyn.
