Rob Hicks
Chief Nursing Officer

Robert (Rob) Hicks has been working in hospitals since his teenage years. Starting as a housekeeper and later becoming a supply manager, Rob developed a love and appreciation for all things “hospital.”

While working as a supply manager in a cardiac catheterization lab, Rob responded to a declining patient that survived the event. He decided at that point he wanted to gain more clinical expertise and went to nursing school at Mohave Community College in Arizona. During his early school years, he worked full time as a Registered Cardiovascular Invasive Specialist and started a family with his spouse. 

Rob spent the last 12 years working as a procedural nurse in cardiac catheterization labs in Utah. The most recent eight years Hicks served as the Director of Critical Care services at Timpanogos Regional Hospital in Orem, Utah. Rob earned his Bachelor’s in Nursing and later a Master’s degree in Healthcare Management.

Rob is loyal to the success of his team and dedicates his profession to the ‘patient experience.’
