Glenn Humphress

M.S., PA - 24 Years

About Glenn:

Glenn Humphress did undergraduate and graduate work at the University of California at Berkeley. He worked as a research statistician at Southwest Research Institute in San Antonio, Texas for many years and ultimately led the Human Performance group at the Institute. 

As a second career, he left research for clinical medicine. He obtained a second bachelor’s degree in Physician Assistant Studies from the University of Texas Medical Branch at Galveston and a master’s degree in Emergency Medicine. He practiced primary care and emergency medicine before retraining in psychiatry. 

He now practices as a psychiatric physician assistant for Dr. Lucas. His focus on human achievement has persisted - helping patients overcome obstacles in their way at school or work are key clinical interests.


Accepts Ages 8 and Up


Why did you choose this field?

Here are a couple of ideas about the "bad days" that we have. We all know what bad days are and when we're having one. We don't need to be taught what a bad day is, by teachers or parents - we just innately know. It's interesting that our knowledge about "bad days" is instinctive.

Up until the Civil War, American tended to believe that if they had a bad day that was because they had offended God and the bad day was their retribution.

That view changed with the Trancendentalist writers like Ralph Waldo Emerson and Henry Thoreau in the 1850's. The Trancendentalists convinced Americans that our bad days are on us. Now, most of us accept that we are responsible for our bad days and for keeping them to a minimum. Thoreau wrote that we have a 'moral obligation' to make progress in our lives - to reform ourselves on a daily basis - to turn our bad days into average or good days. 

According to Center for Disease Control survey data, the typical American has five, or fewer, bad days per month. The typical person presenting for their first clinic visit is having 20 bad days per month. So, knowing that the average person is having five, or fewer, bad days per month is key. My goal is to help them get down below five bad days like most of us have. That is what we aim for and that is what, most of the time, we are able to achieve.
