In 1983, Dr. Sangal opened his practice in the Warren-Troy-Farmington Hills metro area of Michigan.
Three years later, he opened the Sleep Disorders Institute in Pontiac. He soon moved it to the Beaumont Medical Building in Troy. In 1992, he opened the Attention Disorders Institute. In 2009, the Institute moved to a new office in Sterling Heights. It is across the bridge from the Beaumont Hospital in Troy. Four years later, the Sleep Disorders Institute and the Attention Disorders Institute combined. We are now called the Sleep & Attention Disorders Institute. Rhema Management Group purchased the non-clinical assets of the practice on December 31, 2025, followed by M Shaffi Kanjwal, MD purchasing the pratice, and Dr. Sangal retired. We treat patients of all ages. Whether you are one or 101, we can diagnose and treat your sleep or attention disorder.
In our busy facility, we conduct in-center sleep testing. When you come for your sleep test, you will immediately understand why people come to our center. This isn’t a hospital setting. The rooms are decorated like beautiful hotel rooms. We have comfortable beds and bedding. We have the best equipment. We use the correct sensors. We know you aren’t joining us for a vacation. A sleep test is serious business. However, we want to make you as comfortable as possible. We can also help you with in-home sleep apnea testing. We are located in the corner of Sterling Heights, Troy, Rochester Hills, and Shelby Township. Warren, Clinton Township, and Macomb Township are nearby, as are Pontiac, Royal Oak, and Bloomfield Township. We treat all sleep disorders, not just sleep apnea.
Attention Disorders: The common attention disorder is Attention Deficit (Attention-Deficit Disorder or Attention–Deficit/Hyperactivity Disorder). People suffering from ADD or ADHD can be easily distracted. They often do not pay attention to details and cannot stay on task. They have trouble organizing activities. They may be forgetful and lose things. They may be impulsive or hyperactive. All of these symptoms can make home, school and work life difficult.
About 10 percent of males and two percent of females suffer from attention deficit (a brain disorder). It occurs in children and adults. Sometimes, hyperactivity improves with age. The inability to pay attention usually continues into adulthood.
