Dr. Jeremy Sewell, DMD has been working in the dental industry since 2009. He chose dentistry as a career because his dentist, as a child, changed his life through giving him a confident smile. In addition, he loves working with people through health care. Dr. Sewell goes out of his way to show his patients the respect, comfort, and quality dentistry that he gives to his own family.

Dr Sewell’s passions in life revolve around quality time with his children and his enthusiasm for the performing arts. His son and daughter help keep him level headed and compassionate in life. Dr Sewell has also been a dancer since High School. Dance and fitness are his therapies allowing him to feel great physically. He performs locally with the Temecula city sponsored dance company Avocado Dance Theater.

He has given back to the community through the Give Kids a Smile program, as a volunteer counselor for the YMCA, and missionary work in Greece.
