Our Administrative Staff

• A native of Whiting, Indiana and a graduate of Indiana University and ASU with degrees in Biology and Respiratory Therapy, Mark has been in the respiratory field for more than 32 years and spent several years working at St. Margaret's hospital in Hammond, IN where he specialized in Neonatal ICU, Adult ICU and Trauma; later focusing on epidemiology, as well. Mark was raised in Whiting, by entrepreneurial parents; his father, Marvin Finkelstein owned a successful shade and awning company, where Mark worked from the time he was eight, and Rose Finkelstein was the daughter of a grocery merchant. After moving to Phoenix in 1980, due to the colder climates affecting post-surgical arthritis in his knees, Mark worked for Scottsdale Memorial Hospital - Osborn, now part of the Scottsdale Healthcare System. After experiencing the staffing difficulties and lack of customer service with current providers firsthand, Mark founded IRS, where it quickly grew to be the premier agency of choice for hospitals and families seeking care in the home. Now married for 19 years, he has three children - a seventeen year old daughter, and fourteen-year-old identical twin boys.

• Andrea is a native of sunny Phoenix, Arizona.  Born at St. Joseph's hospital and the wife of Mark for over 19 years, her father owned the most renowned rare stamp and coin store, Phoenix Stamp and Coin, with his two brothers.  And, both of her parents were known to own quite a bit of real estate in the valley.  After graduating from ASU in Psychology with emphasis on marketing and advertising, Andrea began EVAN Advertising Concepts.  After building and selling that business, she began to work for MicroAge Computer Stores, and eventually became the Brand Marketing Manager for Compaq Computer Corporation, where she managed a multimillion dollar campaign to grow the brand.  Leaving the computer industry for the auto industry, she quickly became the Fleet Department Manager for Showcase Honda, the largest Honda dealership in Arizona, where she received the prestigious "Gold Award" for the highest in sales and customer satisfaction - one of only a handful to win the award in those years. She left Showcase to work for her husband in 1991.  Together they doubled their already large and thriving  business and created the largest respiratory-only registry in the country.
