Providing you with an experienced

clinical staff for the most advanced care

Our Diagnostic Centers


While patients sleep in one of the bedrooms at our Sleep Centers, technologists supervise the recording of a myriad of physiological functions and measures using state-of-the-art diagnostic equipment. We study the quality and distribution of sleep, brain activity, heart rate, cardiac rhythms, breathing patterns, muscle and limb activity, and other parameters. 


The results are documented and analyzed by our credentialed, registered polysomnographic technologists and interpreted by our Sleep Specialist Physicians at the highest levels of clinical competency in sleep medicine.


Up to 70 million Americans suffer from sleep disorders. Sleep apnea is the most common sleep disorder, affecting more than 40 million adults.

Unfortunately, more than 80 percent of sleep apnea remains undiagnosed, and in some areas of the country, less than 5 percent of adults have been tested or treated for the condition. There is a critical and growing need for timely and accurate screening, assessment and treatment of these disorders.

We are here to help.

Our Patients are Saying...

“Everything, from scheduling the appointment, to the study itself, to the results, was very easy. The night of the study, the staff did everything they could to make sure that I felt comfortable. I felt bad that Kim, the technician, had to listen to me snore all night. The study confirmed what I had suspected, that I have a severe case of apnea and that I stopped breathing

60 times an hour. 
During the follow up to try the CPAP mask, Eddie was very patient and made sure that I was comfortable. The result? The first time in 15 years that I woke up rested. A great experience from start to finish. Pit changed my life and was so easy!”

“5 star rating for Wellfirst :) You will be treated like a Queen/King. Ask for Kim as your tech she was so pleasant and made the procedure actually pleasant!”

“Very nice facility! Friendly staff. Don't wait or be nervous about going."

“You never know what to expect when you do something for the first time. I thought I was going to be in an all white hospital room with wires hooked up all over me and a bunch of people standing around me with clipboards. 
It was NOTHING like that!! It's a very nice homey atmosphere and the rooms are just like a bedroom with super comfy beds and pillows. Kim was my technician and she instantly makes you feel so comfortable. I HIGHLY recommend this to everyone!!!”
