This is what I tried to enter above:DR. JEGA has exceptional medical expertise, gives attentive care, and has a genuine dedication to patient well-being. He takes the time to listen, explain clearly, and ensure I feel supported throughout my visit. I would never think of going to any other doctor and I have the very best in Dr. Jega. All his patients feel this way, I am sure. Thank-you for having him with Trinity.
