Since 1988, our dental home has practiced unwavering commitment to improve our patients' oral health and well-being. We place individualized attention at the core of our practice so that we may get to know you, your family, and your unique dental needs and goals. You will never be rushed in our office. My staff and I value the importance of spending time with you to ensure your understanding of treatment options and why they are necessary, as well as ensuring the quality of treatment. We take pride in meeting and exceeding your expectations so that you always feel confident with a healthy smile. We strive to provide you with a stress-free and comfortable dental experience by offering a warm greeting, personalized conversations, updated technology, and follow-up calls. We also provide amenities, such as free wifi and a coffee bar in the waiting room, and the option for relaxing music, movies, or cable TV in the operatories.

It is our mission to educate and provide our patients with the best dental care in Flushing. For that reason, we've designed this website to provide you with all of the important information you need to make healthy decisions about your oral care. We encourage you to browse our reviews, office page, service details, and patient education library to familiarize yourself with our practice and services. Please feel free to contact our office with your questions. For your convenience, you can also request an appointment online and download patient forms directly from our website. We want all of our patients to have the dental health they desire, so let us help you maximize your insurance benefits or inquire about our flexible financing plans through Care Credit.

We look forward to showing you the difference between a dental office and a dental home
