I know the Dr through a professional relationship and would never recommend her.

I was very happy with the entire staff and Dr. Barker is very knowledgeable and easy to talk to. I would highly recommend them.

I was told I had severe apnea, however the insurance said it wasn't medically necessary. Terrible billing staff, difficult to get a call back, the doctor was full of herself and made me feel stupid. Plus scaring me into my condition being life threatening then denied by insurance. What?!?!? Don't go there. Find another sleep specialist.

She lets for dog roam free in the building regardless of cleanliness issues and potential allergies.
She makes up statistics and makes poor assumptions without thought, exemplified by the claim that my childhood ADHD was caused by fatigue without knowing any details besides the fact that it was in my medical history.
She lies and spreads dangerous misinformation, exemplified by the statement "COVID was engineered to kill fat Americans."
She is greedy and is out to make money, exemplified by how she tried to push me off my sleeping meds, claiming that their use as a sleeping aid was especially addictive and that buying her sleeping meds would magically safer and less addictive for me to use, all without telling me what said medicine was or its composition.
I didn't even get to an actual sleep study, she lost my trust within minutes of meeting her at my consultation, which was after I had finished the staff=acknowledged poorly=written intake forms.

Was sent to Dr, Barker by the VA. She was very informative and really provided me what I needed to get my sleep disorder under control. She told me several things and when I asked her to document those things, she had her staff tell me she would not. I guess she thinks the VA will cut her off. I won't go back and will pay for sleep related appointments on my own from here on out with another doctor. Btw, last time I was there, her staff wanted to schedule me for a daytime study because they said I had indications of a daytime disorder. What a crock of mess and an attempt to get VA dollars. I have never had an issue falling asleep during the day. She also shared HIPAA related info on an employee of mine that was also a VA client that didn't return. She encouraged me to have him come back.....what a scam. I was warned by other medical professionals but gave her a chance. Kind of sorry I did, but still appreciate that I can get decent sleep now.

Dr. Barker only cares about getting your money. Staff lied to me about what insurance covered and then blindsided me with a bill after being constantly reassured that insurance was covering it when it actually was not. When insurance denied certain things, Dr. Barker neglected to inform me and instead gave me those things anyway and then billed me for them later without me knowing. Never listened to my underlying concerns and only tried to add more and more visits to make money for herself.

Dr. Barker is wonderful. She is extremely knowledgeable and thorough in treating my sleep issues and those of my special needs son. I have been a patient with Dr. Barker for over 10 years now. I think she is the best sleep doctor in Knoxville. She is caring and compassionate.

Her lead Nurse was rude after they made me wait forever. Dr. is prissy and more interested in her boots than talking with me. Arrogant and dismissive

East Tennessee Heart Consultants gave my case to Barker after they closed their sleep clinic. Barker lost my records, did not help find them, and apparently has enough business that they do not need mine. I now must start from scratch, going through an entire new sleep study, etc. Total lack of compassion and professional standards.

Did my 2 night study like asked and did all things asked during study. So could find out issues on why can't sleep at night. I came in to apt having questions about results and get nothing but attitude and defense comments. Also says lack of sleep slows down metabolism to make you fat. Why alot of people are over weight. That getting a cpap machine will fix problem of lack of sleep. So everyone who's over weight needs a cpap machine cause that's the problem. When my issue was a hormone problem to which stuck with for life wasted 2000 on getting study, machine, apts done. She doesn't listen to patient at all, she just wants to keep you coming back for more money in her pocket. Horrible bad attitude money gradding doc!!
