The Dallas Center For Sleep Disorders

The Dallas Center for Sleep Disorders was founded in 2006 to help people affected by snoring, sleep problems, or daytime fatigue get the best Sleep Health treatment available, tailored to their individual needs.  Since then, the Dallas Center for Sleep Disorders has expanded its locations and options to better serve our clients in a more convenient and supportive way.  Along the way, we have shortened our name to simply Dallas Sleep.  At Dallas Sleep, our #1 philosophy is to serve our clients and to present you with the best treatment options available.  We are here to meet your needs, as it specifically relates to your Sleep Health.  Therefore, we will never push an agenda on you in any way.  Ultimately, you call the shots. 

We carefully and thoughtfully evaluate our patients before creating a treatment plan that is easy to understand. We are skilled at diagnosing and treating all types of sleep disorders, including snoring, insomnia, sleep apnea, chronic fatigue, excessive daytime sleepiness, restless legs syndrome, sleep walking, night terrors, and narcolepsy. 

Research and clinical experience have proven that sleep disorders contribute to an increased risk of attention deficit disorders (in both children and adults), hypertension, obesity/overweight, type 2 diabetes, cardiac arrhythmias (AFib), stroke, depression, anxiety, dementia, erectile dysfunction (ED), low testosterone levels (low T) and decreased libido.  The good news is that most sleep disorders, when properly diagnosed, can be successfully treated or managed.

Dallas Sleep has been modeled after the Stanford Sleep Disorders Clinic in Palo Alto, CA, which is the world’s leading clinical and research institution in the field.  Our Founder, Dr. Raj Kakar, was trained at the Stanford Sleep Disorders Clinic.  Dr. Kakar’s vision was to bring the cutting edge scientific knowledge and expertise of Stanford to the DFW Metroplex.  Over the years, our evaluation and treatment options to promote Sleep Health have grown substantially as clinical research and technological advancements have moved the medical field forward.
