Coronavirus imageWe continue to operate with as many people and functions as possible within the guidelines set forth by the Minnesota Department of Health and the University of Minnesota. We are adjusting our availability of tests, both in number and frequency, to spare our key resources of time and supplies. Most of our services have not been affected, but please note the changes below that reflect our current adjustments. We will continue to update our website and encourage you to use that as a resource for up to date information. Please contact me if you have questions, concerns or ideas about our services at 612 624-0497 or
