Welcome to Our Practice Welcome to Southlake Dental! Our dental practice has a long history rooted in the beginnings of dentistry in Northwest Indiana, going all the way back to 1932! Today, Dr. Chris Lukasik is proud to carry on the tradition of nearly 100 years of excellence that our patients have come to expect when visiting our Merrillville, IN dental office. Most of our patients have been with us for more than 20 years, and they are part of our extended dental family. We enjoy treating patients of all ages, from toddlers to seniors, and we look forward to welcoming your family to our dental home.
