Testimonials

"I always had trouble getting up in the morning. I never felt I had enough sleep and was sluggish in the morning. I also had trouble falling asleep. My primary doctor referred me to Dr. Hartlieb to get fitted for the sleep appliance. I am happy to report that I now wake up feeling energized and with a clear mind."

So YoungElmhurst, IL

" The Somnomed oral appliance has completely changed my sleep pattern. Before, I would wake up 10 to 12 times every night. Now, I wake up once per night and frequently not at all. I know I am sleeping more soundly, because I have dreams all the time, something that has not happened since I was a child. Most important, I feel far more rested during the day."

BobWinnetka, IL

"After my wife complained about my snoring. I was tested for, and diagnosed with moderate to severe sleep apnea. I was fitted with a custom oral appliance and it has worked wonders. I no longer snore or gasp for air at night. My wife is happy because she is sleeping better at night too!"

MikeHoffman Estates, IL

"My oral sleep appliance is the greatest thing in the world! I love it! I hated wearing my CPAP machine. I couldn't get comfortable wearing it and it would keep me awake at night. My dental sleep appliance is comfortable, it's easier to pack when traveling and I feel better. I feel peppier and refreshed all day long"

BillBartlett, IL

"Last year I was diagnosed with moderate apnea. Dr. French has been the quarterback for my entire treatment plan from start to finish. She successfully fitted me with a custom oral appliance that has cured my apnea, enhanced my sleep patterns at night and given me renewed energy during the day. I highly recommend Dr. French."

JeffCarpentersville , IL

"I wore the CPAP for 6 years and my wife and I really got tired of it. The noise, facial discomfort, and the feeling of always being tied to a hose really wore thin. I decided to try an oral appliance made by Dr. French. What a difference!! I feel well rested and actually sleep better now that I'm not attached to anything. My wife says I have the energy of a 20 year old. Life is good."

WarrenPalatine, IL

"To know something is going on with your child and not knowing how to fix it is the worst feeling in the world. Through much research and guidance from Dr. Pittsley, we are now on the right path. He is a different little boy! He no longer snores, he feels rested all day and has energy to enjoy each and every day to the fullest! "
