Dr. Dimetry B. Cossich

Graduating first in his class at Buras High School in 1978, Dr. Cossich continued his educational pursuits under a full academic scholarship at Tulane University in New Orleans where he earned two degrees; a Bachelor of Arts in Psychology and a Bachelor of Science in Biology. Upon graduating with honors with a Doctor of Dental Surgery Degree from LSU School of Dentistry in 1987, Dr. Cossich continued honing his clinical skills by spending the next two years in a post-graduate, advanced training program at Charity Hospital in New Orleans. Upon completing this program, Dr. Cossich went into private practice and that is where he remains today.

In 1999, Dr. Cossich earned the prestigious Fellowship designation in the Academy of General 

Dentistry. He is also a member of the American Academy of Cosmetic Dentistry, the New Orleans Dental Association, the Academy of General Dentistry, the Academy for Sports Dentistry, the American Dental Association, The Louisiana Dental Association, the Christian Dental Society, the American Dental Implant Association and the Dental Organization for Conscious Sedation. Dr. Cossich is committed to continuing education and takes many advanced courses each year to enhance his skills to better serve the dental care needs of his patients and provide them with gentle and comfortable dental experience.

Dr. Cossich was born and raised in Louisiana, the son of parents who were both school teachers. Even though education was of the utmost priority during his childhood years, his parents also realized the importance of social interaction and outdoor activities in preparing a child for transition to adulthood. To this day, he credits his upbringing for his love of people and his appreciation for the beauty of the outdoors.

"My immediate family, the church and my dental family are the things that are most important to me," says Dr. Cossich who has also earned certification as a Christian Counselor and who was recently ordained as a minister with his church. After 18 years in private practice on the West Bank of New Orleans, Dr. Cossich moved his family to Covington after Hurricane Katrina struck in late 2005. "I love working with kids, coaching basketball, fishing, mountain biking, and water skiing on Lake Ramsey with my wife and family," says Dr. Cossich.
