About

NY Legacy Dentistry, co-owned by Dr. Stephanie Alvarez, D.M.D., and Dr. Yannis Koroneos, D.M.D., stands as a beacon of personalized, high-quality dental care in the heart of Astoria, Queens, New York. Located at 31-79 30th St, Queens, NY 11106, this husband-and-wife practice embodies a commitment to 'Smiles for Generations to Come,' a motto that reflects their deep-rooted dedication to building lasting relationships with patients and fostering optimal oral health within the local community.[2][3] What began as an existing dental office was thoughtfully revitalized by the duo, who modernized the space to create a welcoming, non-traditional environment away from bustling storefronts and main roads. This strategic choice underscores their mission: to serve the Astoria neighborhood with a 'neighborhood type office' offering stronger, more compassionate care than the impersonal, corporate alternatives proliferating in the industry.[3]

Dr. Stephanie Alvarez, a native of Miami, Florida, brings a unique blend of cultural fluency and academic excellence to the practice. She earned a Bachelor's degree in Anthropology with a minor in Education from the University of Florida before pursuing her dental training at Tufts University School of Dental Medicine, where she met her husband, Dr. Yannis Koroneos.[2][3] Fluent in Spanish, Dr. Alvarez connects effortlessly with the diverse patient base in Queens, ensuring clear communication and culturally sensitive care. Dr. Koroneos, a proud Greek-American and lifelong Astorian fluent in Greek, completed his residency at the prestigious Bellevue Hospital Center. His local roots and bilingual skills make him a natural fit for the community he calls home, allowing NY Legacy Dentistry to cater effectively to Astoria's multicultural fabric.[3]

The practice's history is one of intentional evolution. Taking over a pre-existing dental setup, Drs. Alvarez and Koroneos transformed it into a modern haven focused on patient comfort and trust. Unlike corporate offices backed by private equity groups—often criticized for prioritizing profits over people—NY Legacy Dentistry prioritizes a person-centered approach.[3] They recognize common barriers to dental care, such as anxiety and financial concerns, and address them head-on with empathy, transparency, and no-pressure consultations. As Dr. Koroneos aptly puts it, 'We like teeth, but we really like people,' encapsulating their philosophy of treating patients like family rather than numbers on a ledger.[3][5]

At the core of their services is comprehensive general dentistry, complemented by advanced specialties that set them apart. Offerings include Cosmetic Dentistry for aesthetic enhancements, Restorative Dentistry to repair and renew smiles, Implant Dentistry for durable tooth replacement, Invisalign for discreet orthodontic alignment, and even Botox treatments for therapeutic and cosmetic relief.[2] This diverse portfolio ensures that patients receive holistic care under one roof, from routine cleanings and preventive measures to transformative procedures, all delivered in a comfortable, friendly environment by a team of experienced professionals.[1][2]

What truly distinguishes NY Legacy Dentistry is its unique value proposition: genuine, community-driven care that contrasts sharply with the 'corporate style offices' dominating the market. The doctors' personal involvement—as spouses and partners—infuses every interaction with warmth and attentiveness. They emphasize optimal oral health without upselling, building loyalty through exceptional patient experiences that encourage repeat visits and referrals. Operating Monday through Wednesday from 9am to 5pm and Fridays until 6pm, the practice maintains accessible hours for working professionals and families alike.[3] Their innovative, patient-centered methods, highlighted in local features, position them as 'the Astoria dental team everyone's talking about.'[3]

In an era where dental visits can feel transactional, NY Legacy Dentistry redefines the standard by blending cutting-edge expertise with heartfelt service. Whether addressing dental anxiety, providing multilingual support, or delivering results that last generations, Drs. Alvarez and Koroneos have created a legacy of trust and excellence. Patients aren't just leaving with healthier smiles—they're gaining partners in their lifelong oral health journey. This commitment to quality, community, and compassion ensures NY Legacy Dentistry remains a cherished cornerstone of Astoria's healthcare landscape, inviting new patients to experience dentistry done differently.[2][3][5] (Word count: 612)

I had been seeing my previous dentist for years and was always very satisfied with his cleanings and fillings. When he retired last year, he referred me to Dr. Koroneos at the same office. Dr. Koroneos took great care of me right away — he did a cleaning and a small filling, and everything was excellent. Later, my fiancé also needed a cleaning, so we went back to the same office. By that time, the practice had been transitioned to Dr. Koroneos’ wife, Dr. Alvarez. Since December, we have both been regular patients there. We’ve had cleanings, fillings, and even whitening treatments, and we’re extremely happy with the results. One of the things I love most is their new technology: you can see your entire mouth in 3D on a touch screen, rotate it with your finger, and view your teeth from every angle with amazing accuracy. It makes everything so much clearer and more interactive. I also want to mention their receptionist, Eleni. She is incredibly kind, warm, and professional. She always greets us with a smile, calls ahead to confirm our appointments, and makes sure everything runs smoothly. Her friendly presence adds so much to the welcoming atmosphere of the office. Dr. Koroneos and Dr. Alvarez are excellent professionals — friendly, approachable, and very thorough. Their team is wonderful, and the whole experience is top-notch. I highly recommend them to anyone looking for a dentist who combines experience, technology, and genuine care. Ευχαριστώ

My periodontal surgeon highly recommended Dr. Yanni Koroneos in Astoria, which is not far from where I live. I went for a cleaning and he spent so much time with me explaining all of my dental issues and what I should look forward to in the future. This is not a corporate dental Mill where they seem to just want to do more and more procedures for the money. I felt very relaxed and comfortable in this office. This was probably the best dental visit I’ve ever had!

A True Professional with a Heart of Gold Dr. Koroneos is hands down one of the best dentists I’ve ever had the pleasure of visiting. I came in with a problem molar, and not only did he do incredible work, but he also went above and beyond to make sure I was comfortable every step of the way. From the moment I walked into his office, I felt like I was in good hands. He took the time to explain everything in a clear and reassuring way, and you could tell he genuinely cared about getting things right—not just quickly, but perfectly. His attention to detail, steady hand, and compassionate approach made what could have been a stressful visit feel smooth and even pleasant. It’s rare to find a dentist who combines skill, professionalism, and kindness the way Dr. Koroneos does. If you’re looking for someone who will treat you like more than just a patient and truly care about your experience and outcome, I can’t recommend him enough. Five stars all the way.

Dr. Stephanie is amazing! I went in for a cleaning today, and after getting it done by her, I realized I never had a proper cleaning before from any dentist! She is very detailed, patient, and caring. She took her time - did an amazing job - I did not feel rushed out of the office at all! They have very high tech tools in there, she showed my treatment plan on the tool it was very easy to understand. I'd recommend to anyone!

Love love love this office. Dr. Koroneos and Dr. Alvarez are true professionals! The office is clean and staff is friendly. Helen at the front is the best and will go out of her way for you. This is NOT a big box corporate office that will make you feel like a number. I always feel comfortable here and have referred all my friends and family that are in Astoria.
