Review of Dr. Robinson Jr

-Knoxville |

Dr. Robinson is a wonderful doctor. After suffering with sinus infections and nagging coughs for years, I have not had those issues and feel so much better as a result of his prescribed treatments. He cares about his patients and is a great diagnostician. I do not hesitate to give him my highest recommendation.

Review of Dr. Singer


We've seen a lot of Allergists and Dr. Singer is by far the best. He personally calls with test results and truly cares about his patients. His knowledge surpasses any we've encountered and highly doubt one exists that could surpass him. We primarily use the office off Highland and find the staff friendly, helpful, and competent as well.

Review of Dr. Singer

- in Knoxville, TN |

My wife's an MD. I'd been "self medicating" for allergies since we moved to Knoxville 10 years ago. Just thought I'd be miserable from living here, as the allergies weren't "seasonal". Finally made an appointment. He identified my allergies which I'd never thought of, and within 2 days I had felt better than I had in 10 years. Great guy who also treats my kids, and has a great bedside manor for both kids and adults.

Review of Dr. Ellenburg

- in Knoxville, TN |

He is my second choice when consulting regarding my Asthma allergy. He has been treating me since past few years, and all his prescribed medicine works for me. Although, I had switched my doctor for a change to see if I can get better results from a different doctor.

Dr. Singer is a wonderful doctor. He takes the time to talk with you and get to know you. He is very patient and willing to help. My teenage son and I are both patients of his, and my son has never been happier with a doctor than he is with Dr. Singer.
