Dr. Marin-Rojas leads a practice that is built on a foundational philosophy: every patient is unique, and their dental care should be as well. The practice is designed not just to treat teeth but to care for the whole person, emphasizing education, prevention, and long-term relationships over isolated procedures. The journey at Union Square Smiles begins with a comprehensive consultation, where time is taken to listen, understand patient goals and concerns, and perform a thorough examination using state-of-the-art diagnostic technology. This collaborative approach ensures that every treatment plan is co-created, transparent, and tailored to achieve optimal oral health and aesthetics that align with the patient's lifestyle and expectations.

With a profound understanding that a beautiful smile is a powerful asset to confidence and well-being, she specializes in cosmetic and restorative dentistry that looks incredibly natural and functions flawlessly. Her expertise extends across a wide spectrum, from routine preventive care and periodontal therapy to complex full-mouth reconstructions and clear aligner orthodontics. The practice is equipped with modern technology, including digital X-rays and intraoral cameras, which enhance diagnostic accuracy, patient understanding, and comfort. Furthermore, the bilingual capabilities of the team (English and Spanish) reflect the diverse fabric of New York City, making comprehensive dental care accessible and comfortable for a wider community. Operating in the dynamic Union Square neighborhood, the practice attracts a diverse clientele—from busy professionals and students to families and artists—all seeking a dental home that is both highly competent and exceptionally compassionate. Dr. Marin-Rojas and her team are known for their gentle chairside manner, particularly in alleviating dental anxiety. They create a calming environment where patients, including those who have avoided dentistry for years, feel heard, respected, and at ease. The mission of Union Square Smiles is to empower patients through knowledge and provide dentistry that enhances health, function, and beauty for a lifetime. This commitment to excellence, personalized care, and building genuine trust is the cornerstone of the practice, making it not just a dental office, but a dedicated partner in the long-term oral health journey of every individual who walks through its doors.

My husband and I have been seeing Dr. Nancy Marin Rojas for over 20 years. She is talented, professional and caring. Whenever I have an issue, she is willing to find a way to fit me into her schedule. Her work is immaculate and my children use her as their dentist as well. I have recommended her services to so many people and everyone finds her to be incredibly reliable, trustworthy and talented.

Great dentist, she was able to put in my crown in 1 visit. Looks great, really happy with the whole experience.

So, I read the reviews and was a little skeptical, but that quickly changed from walking up to reception and her relatability, the friendly dental hygienist, to Dr. Corey who could not have been more professional, personable and completely thorough. And yes, the latest technology was a bonus! I recommend Union Square Smiles! 😀✅

My whole family has been seeing Dr. Marin Rojas for more than a decade. She is wonderful: communicative and gentle. She really makes sure that you have a painless experience! Her staff is warm and friendly, and I lover her new office. She is the dentist I refer to anyone who asks me for a recommendation for one.
