“RBB Architects has collaborated with Millie and Severson on the Master Plan of the PIH Health campus for the last 25 years. The completion of the Perry Pavilion, Scheifly Breast Center, Pediatrics Unit, Shannon Tower, and the recently completed Plaza Tower, have all resulted in great reviews from the staff, patients, and hospital administration. The success in construction is due in large part to the leadership provided by Millie and Severson, and their ability to consistently deliver high quality, complex health care projects on time and on budget.”
