Dr. Alexander

Leena Alexander, D.D.S., FAGD


Dr. Alexander is the dentist at Starshine Dentistry in Corinth and recently took ownership of the practice in December 2018. She graduated in 1999 from Marquette University School of Dentistry as a Doctor of Dental Surgery and also holds a degree in Dental Surgery from Annamalai University. Beyond that, she averages roughly 120 credits per year in continuing education. With more than 18 years of experience in general, preventative, surgical, and cosmetic dentistry, her goal is to provide gracious, comprehensive care with a gentle touch that translates into long-term oral health, beauty, and satisfaction for her patients. In that time, she has developed trusting relationships with some of the leading oral surgeons, TMJ specialists, periodontists, orthodontists, and endodontists in the country – helping to create a top-notch dental experience for her patients.

Dr. Alexander is a firm believer that prevention is better than cure, and her diligence and commitment to perfectionism is a big reason why she continues to bring a confident smile to her patients’ faces. More than just a dentist, it’s not uncommon for her to have her hands in all aspects of patient care, whether that be answering and returning phone calls, scheduling appointments at the front desk, and even calling patients shortly after a dental visit simply to check in on their progress.

In her spare time, Dr. Alexander and her husband, Steve, enjoy traveling, spending time with their children, designing semiprecious jewelry, and gourmet cooking. She also regularly integrates mission work into her schedule, particularly when it comes to children living in underprivileged socioeconomic conditions.
