"Dr. Shellenberger’s office is very nice. Not crowded at all and completely followed the CDC protocol for the COVID-19 virus. The office staff are very nice and friendly. Mariah, Dr. Shellenberger’s assistant, was impressive, thorough and made me feel very comfortable. Dr. Shellenberger was informative, thorough, and spoke to me in laymen’s terms which was a major help to understand my issues. I would definitely recommend Cross Timber’s ENT office, staff and doctor to anyone needing a Specialist. I left feeling very relieved and happy."



"I'm a newish patient of Dr. Shellenberger. I really like him. He is quiet and kind. He's very knowledgeable. I've had three surgeries with another doctor. Dr. S tried everything not to do another. After several months he decided he needed to. After a few weeks I'm feeling better. He's very knowledgeable and told me about ongoing information of my condition and with that decided to stay away from a problem that could heal itself. Originally we thought he may have to work on it too. "



"Great and friendly staff. Dr. Shellenberger cured my infection that I had for 3 yrs!!"



"Our daughter is a performing artist and Dr. Luke understands the needs and challenges of vocalists. His kind nature and thorough understanding of the relationship of ENT issues to vocal performance was just what we were looking for. He is always efficient, yet doesn't make you feel rushed. He considers conservative measures first, but has relationships with other specialists if needed. Dr. Luke is honest, enthusiastic, and knowledgable."



"The staff is very friendly and professional. Dr. Shellenberger answers all my questions and explained the diagnosis so that I'm able to understand and how he's going to proceed in treating me."
