Cal Halvorsen publishes study in the American Journal of Preventive Medicine

Cal Halvorsen, an assistant professor, has found that wealthier older adults are more likely to volunteer, but lower-wealth volunteers may gain even greater health benefits from the experience. 

His findings were published in the American Journal of Preventive Medicine under the title "Volunteering as an Equalizer: A Quasi-Experimental Study Using Propensity Score Analysis."
