Meet Gerard Valcarenghi, MD, MPH

Dr. Gerard has practiced pulmonary medicine for over 30 years, holding several medical directorship appointments in critical care, including the Medical/Trauma Center's Respiratory Dept., RICU (Respiratory Intensive Care Unit), the Respiratory Rehabilitation program & PFT lab at Enloe Hospital & Medical Center in Chico, CA, St. Elizabeth Hospital & Butte College Respiratory Care Program. He is also credited with developing the sleep disorders department at Enloe.


One particular area of focus & research for Dr. Valcarenghi is sleep disorders. He has spoken to professionals & the public to understand the underlying physiology of sleep disorders, an area of growing incidence & sophistication of treatment for patients.


Dr. Valcarenghi obtained his master's degree in public health (MPH) from Loma Linda University Medical Center in California, researching pulmonary exercise physiology, nutrition & preventive medicine. The physiology of respiration is of particular interest as it relates to the upper airways in concert with the lower airways & how poor physiology of sleep results in system diseases, not to mention neurologic deficits and obesity, which often exacerbates the underlying sleep disorder.


As one of the North State Sleep Lab principles, he has a veritable wealth of experience in Sleep Disordered Breathing or SDB. We are delighted to add Dr. Valcarenghi's wealth of knowledge & expertise to Radianté as a consulting physician.


Dr. Valcarenghi is also an accomplished classical pianist, avid runner & is now constantly running to keep up with his three young children.
