Dr. Anne Korkis

General Dentist

DDS, B.Sc, M.Sc.
As a graduate from New York University College of Dentistry I have strived towards enhancing Manhattan’s smiles one individual at a time. I continued my education with residency at New York Presbyterian hospital in Park Slope and have since been continuing to do full mouth rehabilitation whether it be by simple fillings to crown/ bridges, or maintaining oral health.

My biggest asset I would say would be my ability to relate to my patients with compassion and empathy with realism while making their experience as pleasant as possible. On my spare time you will find me traveling to Toronto and London visiting my family, or often on the slopes of the steepest mountains plowing through on skis. I’m an athlete by nature, but my greatest strive is giving my patients exactly what they want and as easily as possible.

Dr. Korkis hold various titles and recognitions, including:

Dual certification by both the American Board of General Dentistry and the Royal College of Dental Surgeons in Canada
Certification of General Practice Residency from New York Presbyterian Brooklyn Methodist Hospital
Tulsa Dentsply Award for outstanding clinical skills and knowledge of literature in endodontics from NYUCD
Award of Scholarly Achievement and Excellence by NYU
American Board of General Dentistry - certification badge
Certification Badge of Royal College of Dental Surgeons Ontario

Saloni Angra BDS, DMD

Saloni Angra BDS, DMD

Dental Hygienist

My main goal ever since I started my profession has been for the person sitting in my chair to feel better after their visit and to that end I make sure to be patient and listen to every ailment that is facing my patient before making a decision about their treatment.

I started my dentistry journey in 2007 when I started dental school in India. After 5 years of rigorous training which included treating underprivileged people in rural India, I had the opportunity to move to the United States. Here I worked as a dental assistant for a year while simultaneously applying to dental schools. My dental pursuit took me to Tufts University in Boston where I obtained my DMD .

Following my DMD I worked in an office in greater Boston area, where I treated patients from all walks of life and of various ages.

I am fully aware that people have reservations coming to the dentist’s office but over the years I have learnt the art of patience and being a good listener since I understand it is tough to be vulnerable and open up about one's health. I try my best to make my chair a judgement free zone where I will be compassionate and empathetic about your needs. If there is something that I can do to make you feel better no matter how trivial it might seem, I will do it since my job as your dental provider is for you to walk out of this office feeling like you received the best care possible.

To your forever beautiful smile!

Hello, my name is Lea Carrillo and I am a board certified dental hygienist at ADA. I was born and raised in the suburbs of New York and moved to New York City in 2017. I take great pride in providing my patients with the utmost care and I love educating all of my patients on how to maintain a healthy oral cavity and the link between this and their overall health. I took a liking to dental hygiene when I shadowed an office in Upstate New York and really felt that I could make a difference in the overall well being in a persons health. I also make sure to follow up on all of the most current advances and practices in dentistry that can benefit all of my patient. On my free time I enjoy bike riding, hiking, and the outdoors, I find that it's important to maintain an active life and have a healthy balance between your external and internal well-being.
