Donna Front Desk Coordinator

5-Star Dentistry & More

"Those Things That Are Best" is the motto of the fine school where I spent most of my English Literature teaching career, but in Dr. Byron McKnight's dental practice in Mesquite I have found another home for that motto of excellence. I experienced excellence in every part of my visit, from Donna's warm and professional "hosting" and interviewing at the front desk, to Amy's smooth, proficient dental assistance, to Dr. McKnight's intelligent, patient, and comprehensive analysis of my dental health. His expertise and dialogue is absolutely clear in discussing bio-mechanical, chemical, and nutritional elements. I have the confidence that the whole team is working together for my best treatment plan, and I look forward to my next visit. I had another great visit on Tuesday, 23 March 2024. Dr McKnight and Dr Olga Stepanchenko both conversed with me about a tooth repair in the clearest way possible, and Dr Olga again very skillfully performed the repair with her usual professional expertise and personal, friendly style. Dr. McKnight repaired another tooth for me on July 3, 2024, and I want to praise the excellence of his work again, along with excellent interactions with Donna, Amy, and Brook" Richard B. Mesquite, TX

"The staff is professional, friendly and cares about each patient that walks through the door. Dr. McKnight and Dr. Olga are exemplary dentists. They take time to explain the best options for your dental care and let you choose… no up selling. Your experience will be extremely professional with people that really care." Nancy S. Mesquite, TX

"I took my son to Dr. Olga for his dental fillings, and I couldn’t be more pleased with the experience! As a mom, it’s always a concern when your child has to go through any dental procedure, but Dr. Olga made the whole process so easy and stress-free. My son was comfortable the entire time. She was so patient and kind, explaining everything to him and making sure he was at ease. We had such a positive visit, and I’m so grateful for Dr. Olga’s care!" Leis

"I love everything about McKnight Dental from the outstanding customer service to the welcoming ambiance of the office! Dr. Olga is the best, she knew all the answers to my questions, very professional and helpful. I am proud to say I am a new patient" Jornai S. Dallas, TX

“I’ve been terrified of the dentist for 40 out of the 45 years I’ve been alive. That being said, I’ve never felt more at ease than when speaking with Dr. Olga about my treatments, and what we can do to improve my tooth health. I will never go to a different dentist again." David R. Dallas, TX

“My initial intake experience was amazing. The reception staff was considerate and friendly. The initial exam was completely thorough. Dr. Olga was kind, gentle, an excellent listener and understanding of my previous dental history. Her evaluation was thorough and her recommendations very helpful. Dr. Olga's dental assistants are also very gentle and caring. They are knowledgeable and skilled in their roles. My return visit for needed work was consistent with the initial exam. Dr. Olga was as gentle and caring as before. I plan to continue with my dental care from Dr. Olga and her staff. When it is time for my son's dental visit, I plan to bring him as well." Rosemarie J. Dallas, TX

"Dr. McKnight and his staff are so professional! They explained each step of the procedure as it was performed and at the end of the visit Dr. McKnight asked if I had any questions. I have not experienced that with any other dentist. I really appreciate the exceptional care that he and his staff provides." Janet S. Dallas, TX

“If you are looking for the definition of what it means to be "the best," you need only schedule an appointment to enlist any of the many services provided by McKnight Dental. Dr. McKnight not only has made an art form of dental work, he operates from the heart. You sense this the moment he sits down with you and explains the details of what dental work may be necessary for you, and does it in terms you can understand. When the work is done, the follow-up is just as impressive as the work done in the office. Thank you, McKnight Dental! Robert R. Garland, TX

“I was so pleased with my appointment! Everyone was so nice. Sometimes a professional doesn't realize how important their staff is in the eyes of their patients. I felt relieved to have found a dentist that I trust. I now feel I have started getting things back to normal in my life. I honestly feel I am in the good hands. Thanks. Carol A. Dallas, TX

“I've been going to Dr. McKnight's office for many years. Every experience was perfection. The entire office is so nice and caring. Donna is such a joy at the front desk. I look forward to my cleaning with Millie every six months. I'm not surprised that Dr. McKnight has won so many awards. In 2009, Dr. McKnight received the Lifetime Achievement Award from the Academy of General Dentistry, an award which had been given to only 80 dentists in the world!” Mary W. Dallas, TX

“Dr. Byron McKnight and his staff are simply amazing in every way. They are warm, caring, attentive, fastidious, and exceptional. The office is pleasantly inviting and the staff greets you with open arms. Dr. McKnight is extremely skilled and innovative. After dealing with many years of snoring and doing a sleep study and using a CPAP machine to no avail, he suggested he fit me for a TAP appliance. Within weeks my appliance arrived and for years it has absolutely changed my life.” D.F. Garland, TX

“Dr. McKnight is the BEST dentist I've been to beyond a doubt. Honest. professional, conservative and genuinely helpful for the long term. His attention to details and calm reassuring manner is beyond words. He takes time to really know your concerns. Fully recommend!” Mesquite , TX

Being a great dentist is about much more than just helping nearby patients in the treatment chair. Our team strives to be active in not only our local community, but in underserved areas around the world as well! Dr. McKnight has regularly performed free care locally in his office, as well as working with Mission East Dallas (which he helped to establish over 20 years ago) and Mesquite Social Services for patients in need.
