    A Unique Path to His Dental Career

    Before becoming a dentist, Dr. L was a computer programmer, student pilot, and worked with his family in the restaurant industry. But he never gave up on his dream of becoming a dentist. Through plenty of hard work, late nights, enthusiasm, and the support of his family, he became the dentist he had always wanted to be.

    Dr. L graduated from Case Western Reserve University School of Dental Medicine in Cleveland Ohio, where he earned a Doctor of Medical in Dentistry (DMD) degree with Rank #1 in class in terms of clinical experiences. After graduating, he attended a residency, Advanced Education in General Dentistry program at the Dayton Veteran Affairs Medical Center. His residency brought him with much experience in treating a high volume of difficult cases and helped him understand medically compromised patients.

    Dr. L loves all aspects of dentistry, including restoration, crowns & bridges, implants, endodontics, and removable prosthesis, either partial or complete denture. He’s also a certified provider of Invisalign clear aligners.

    Dr. L always treats his patients like his family members, and those patients love him for his competence as well as compassion.
