Dr. Whirter is my 2nd sleep Dr. He helped me fix problems that plagued,me for years. He listened to my complaints and help me get the relief I needed. I highly recommend him.

He Doesn't Listen to me. Didn't prescribe what I needed. Didn't review my medical record, didn't check my breathing rhythm. Lousy Doctor!!!!!!!! Do not use!!!!!!

I was charged $323 for the visit with a nurse practitioner that lasted approximately 10 min. I was not informed this would be the cost. After my discount I still had to pay $109.44 to speak to the girl. I did not get a sleep study. I will never, ever recommend this doctor's company (Tranquility Sleep Specialists PLC) to anyone. I never met Dr. McWhirter but clearly he thinks it's okay to code a mere consultation as an Outpatient Procedure and then charge you thusly. Shameful!
