Our Team



Dr. Alex Reznikov


Dr. Reznikov grew up in the suburbs of Chicago. Coming from a family of dental professionals, it was natural for him to develop a passion for treating patients with dental needs. After finishing his studies at the University of Illinois College of Dentistry, he and his wife moved to Milwaukee to pursue a great opportunity to work and obtain hundreds of hours of Continuing Education. After he and his wife found out that they were expecting their first son, they decided to move closer to home to be closer to family, friends and the city they always loved. At the same time, Dr. Reznikov was looking for a practice he could call his own, and luckily the Dental Group of Chicago was ready for a transition.

After enlarging the scope of practice and turning the group into one of the finest dental groups in the South Loop of Chicago, he decided that he would help other practices reach higher levels by implementing management that could allow dentists to concentrate on delivering excellent clinical dentistry. This is why he and his father, Dr. Vladimir Reznikov, became the owners of Dental Group of Bloomingdale. He is currently working on his Fellowship at the Academy of General Dentistry, as well as a membership in the International Congress of Oral Implantologists. He is passionate about education, and provides opportunity for every doctor that he works with to continue their education as well. In his free time, Dr. Reznikov loves to travel, cook with his wife, spend time with his little one, friends, and family, and ski.
