I had been on sleeping pills for years but I was still waking up a lot at night. He found I had sleep apnea and now I'm off the pills and sleeping much better with my CPAP. Very nice doctor who knows his stuff.

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!
