As a dentist myself, I chose Dr. Chae to do my dental work because i've been following him for…read moreyears on Instagram and have seen that he does exceptional dental work and diagnosing. Couldn't be happier. I had to have a couple fillings redone that that were acceptable, but not the best. He took pictures along the way to show me the before and afters and I can attest that he takes pride in his work. He's a perfectionist, which means he may diagnose a few more fillings than your average dentist, but as a dentist myself, I would agree that all the fillings diagnose were valid and needed to be done (even if it was a small problem) and the result was something much better after. I'll be back for any other dental work.

Choosing orthodontic treatment for your child is never a small or simple decision for a parent…read more The treatment can take a long time, and there are so many things to worry about. Will my child be in pain? Will she feel scared during the process? Which orthodontist can I truly trust with my child? Before starting Elena's orthodontic treatment, I had many concerns and carefully considered all of my options. After giving it a great deal of thought, I chose Steve S. Lee, MS, DDS, and now I can say with complete confidence that choosing Dr. Lee was one of the best decisions I could have made for my daughter. From our very first consultation, Dr. Lee never rushed us or overwhelmed us with complicated medical terminology. He carefully explained Elena's current dental condition, why orthodontic treatment was needed, and how the entire treatment process would proceed, step by step. He explained everything thoroughly so that I could fully understand as a parent, while also speaking directly to Elena in a gentle and child-friendly way so that she would not feel frightened or overwhelmed. That was one of the first things that truly impressed me. Even adults can feel nervous sitting in a dental chair, so I can only imagine how intimidating it may feel for a child. The sounds of the dental equipment, unfamiliar tools, and having something placed inside the mouth can all be uncomfortable and frightening. However, Dr. Lee never rushed through the appointment. Before doing anything, he calmly explained to Elena what he was about to do. He would gently tell her what was happening and reassure her throughout the entire process. He repeatedly asked her, "Are you doing okay?" "Does anything hurt?" "Are you uncomfortable?" "If anything bothers you, please let me know." Throughout the treatment, he continuously checked on Elena and carefully watched her reactions. Whenever she looked even slightly uncomfortable, he paused and made sure she was okay before continuing. It was clear that he was not only focused on placing the orthodontic appliances correctly. He was also taking care of my child's emotions and making sure she felt safe. As a parent, those are the moments that bring the greatest sense of relief. Dr. Lee did not treat Elena as simply another patient in the chair. He treated her as a child who might feel nervous, scared, or uncertain, and he showed genuine patience and respect toward her feelings. His kindness never felt routine or superficial. He took the time to make sure Elena understood what was happening. He patiently waited for her when she needed a moment, answered every question, and explained things again whenever necessary. He also listened carefully to my concerns as a parent and never dismissed any of my questions. His explanations regarding the treatment were extremely detailed and clear. He kept us informed about Elena's current progress and what to expect in the future. Because of his careful communication, many of the worries and uncertainties I had before beginning treatment slowly disappeared. Most importantly, watching the calm and caring way he interacted with Elena gave me complete confidence that we had found the right doctor to guide us through this long journey. Orthodontic treatment is not something that is completed in one or two visits. It is a long process that requires trust and cooperation between the child, the parents, and the doctor. Because of that, I believe a doctor's character and communication are just as important as professional skill. Dr. Lee truly has both. Elena was able to stay calm and cooperate throughout her treatment because he continually reassured her and carefully checked whether she was experiencing any discomfort. As I watched him notice even the smallest changes in her facial expression, I quietly felt grateful over and over again. I kept thinking, "We truly found a wonderful doctor." "I made the right choice for my daughter." For any parent who is wondering where to begin their child's orthodontic treatment, I sincerely recommend Steve S. Lee, MS, DDS. He is warm and gentle with children, clear and thorough with parents, and genuinely attentive throughout every part of the treatment process. We feel incredibly fortunate to have found a doctor who does not only care for a child's teeth, but also cares for the child's heart and emotional comfort. We still have a long way to go in Elena's orthodontic journey, but I feel completely comfortable moving forward because I trust Dr. Lee. Thank you, Dr. Lee, for always speaking kindly to Elena, for carefully checking whether she is in pain or uncomfortable, and for easing the worries of a concerned mother. Out of all the decisions I had to make regarding Elena's orthodontic care, choosing Dr. Lee was truly one of the best decisions I made. I am deeply grateful, and I wholeheartedly recommend him to every parent searching for a kind, trustworthy, and exceptional orthodontist for their child.
