It has always been Dr. Lehan’s vision to provide treatment to patients in the same manner he would his own family.  This is the driving force that has pushed him to seek over 600 hours of continuing education.  Throughout the years, he has attended the prestigious Pankey Institute, The Dawson Center for the Advancement of Dentistry, The Orofacial Pain Center at the University of Kentucky, and a variety of other CE programs. 

Dr. Lehan’s enthusiasm for education has allowed him the opportunity to return to his alma mater in 1998 to lecture on the subject of halitosis and continues this annually.  In 2004, he became a Clinical Assistant Professor teaching part-time at the University of Mississippi School of Dentistry.


Dr. Lehan opened Dental Care of Clinton in 1997 upon returning to Mississippi.  He is married to the former Diane Brown of Clinton.  They have four children and reside in Clinton.  Dr. Lehan is a member of Holy Savior Catholic Church.  In his spare time, Dr. Lehan enjoys marathoning, biking, skiing, and spending time with his family.
