Dr. Isaak
Moving to the United States as a child, Dr. Isaak felt self-conscious about his oral health and appearance. His ability to access quality dental care was impossible in his former country; however, once he met with a caring and compassionate orthodontist at 13 years old, he began to witness the positive changes occurring inside his mouth.
After graduating from the New York University College of Dentistry with high honors, he served as a member of the Omicron Kappa Upsilon National Dental Honor Society. He completed a general practice residency at New York Methodist Hospital in Brooklyn, NY, – a place where he fell in love with orthodontics. He eventually pursued an orthodontic residency at St. Barnabas Hospital in the Bronx.
Simpli the best! Feeling blessed to have met Dr Yelizar. I got braces 3 times (span of 25 years), Dr Yelizar is my 4th ortho and he finally fixed my issue. He is a problem solver, perfectionist, and extremely passionate about his work. Followed Dr Yelizar on Instagram for 2 years and thought he was in Connecticut. After 2 years, I checked again hoping he relocated to New York City. To my surprise, he was always in Forest Hills. So I am very glad he is now my orthodontist. I highly recommend Dr Yelizar !

Both braces and clear aligners can straighten teeth, but the best option depends on your bite, tooth movement needed, and lifestyle. Aligners are popular for aesthetics and removability, while braces can be better for more complex corrections or highly precise movements.
Yes, many of our patients travel from nearby Syosset neighborhoods for orthodontic care. We regularly welcome families from Elmhurst, Forest Hills, Corona, and surrounding areas.
If your child is developing bite or spacing issues, early orthodontic guidance can help prevent bigger problems later. Early interceptive orthodontics may address concerns like protruding front teeth, underbites/overbites, and crossbites that can contribute to uneven jaw growth or excessive wear.
We accept the vast majority of orthodontic insurance plans. Even if you don’t see your provider listed on our website, it’s worth calling our office to double-check your coverage. Orthodontic insurance can reduce your out-of-pocket expenses, after all, and you won’t have to worry about paperwork – we’ll handle your claims on your behalf.
