About
RestAssuredRx strives to eliminate the adverse effects of Sleep Apnea and help you live your best life.
RestAssuredRx was started to help people live their best life by making sleep testing and care affordable while offering it in the most convenient location for the patient; their home. We provide an easy to use, convenient, low-cost approach to the diagnosis and treatment of sleep conditions. Lack of quality sleep can lead to loss of work productivity, moodiness that can lead to strained family tensions, and other serious health complications, including high blood pressure, stroke, and type 2 diabetes.
Better Sleep Equals…
Better Health and a Better Life
Far too many people underestimate the value of sleep. A good night’s rest is not just something that helps you get through the day; it is a vital part of your health. If you consistently have difficulty sleeping through the night, you are at risk of developing severe health conditions like heart disease and clinical depression. At RestAssuredRx, we want to help you obtain the peaceful sleep you deserve to live a better, healthier life. Our Sleep Disorder practice offers consultations, in home sleep studies, and treatment options for individuals who may be affected by a sleep disorder, including obstructive sleep apnea. The practice is made up of physicians whose medical areas of focus are in general medicine, neurology, and sleep medicine. We are also equipped through our partners with an on-site sleep lab for additional diagnostic testing.
We welcome you to better sleep, which leads to a healthier, happier, and more productive life.

Dr. Mastrin, MD
Marcia Mastrin, MD is originally for Chery Hill, N.J where she was in General Practice after her residencies in Internal Medicine at University of Medicine and Dentistry of New Jersey now known as the Rutgers Robert Johnston Wood Medical School in Camden, N.J and at Jefferson University Hospital for Radiation Oncology. She had her own thriving General Practice for 15 years in N.J. She fell in love with the Arizona while still in Medical school so when she and her husband became “empty nesters” they decided to get out of the cold and moved to Arizona where they could enjoy the sunshine and ride their horses all year long. She has been in Arizona practicing medicine for 18 yrs now and still loving it here.
She went into General Medicine because of her compassionate and caring nature. In this field, she could encourage patients to care for themselves, watch them get healthier both physically and mentally and hold the hands for those who would not. Also, in this compacity, she could wear many hats and treat patients with all kinds of conditions and be knowledgeable about them. Her main goal and dedication is teaching patients those preventive tools that will lead to a longer and healthier life style, which became foundational to her entering into sleep medicine. She is a grandmother of 2 lovely boys and 2 wonderful step-granddaughters. She no longer rides but still loves horses, she is an avid reader and tries to stay healthy herself by exercising and eating well, so she can continue to serve her patients.
