I have worked closely with IRS over the past year, and I am very pleased with the services they provide. I regularly refer patients to IRS to test and be treated for sleep apnea. My patients tell me that their experiences with them are positive, and this is important to me. I strongly recommend that Physicians use IRS to test and treat patients they suspect have sleep apnea. IRS strives to find ways that they can add value to my practice, and this differentiates them from their competition.
