She used her educational credits and patient contact hours to pursue her dream of becoming a PA by attending DeSales University. She earned her Master’s Degree in Physician Assistant Studies and started her journey of helping those in need.

Laura has a young family that takes up most of her “free time,” but that is just her family’s season of life. Laura and her family love the outdoors, animals, and exploring the different natural wonders around them. They love long hikes, biking, and anything to do with the water. They are committed as a family to do volunteer work and donating to different programs in their communities. They travel frequently with all modes of transport, and love finding little nooks that are off of the well-worn path.

“I had the pleasure of meeting super friendly and professional Physician Assistant Laura McDonough who gave me a very thorough exam, explained her findings, and provided a solution. I will be using this office in the future for any urgent care needs.”

He did not waste time with x-rays or tests, even though most places would have checked if I sprained the ankle or damaged bone or cartilage. In the end his evaluation and knowledge is ending me to the ER may have saved my ankle as I had an infection in the ankle and it only takes a few days to destroy your joint cartilage.

“… In desperation I contacted Advanced Urgent Care and after a same-day virtual appointment with Marisa, PA, she was able to diagnosis an acute sinus infection and prescribed an antibiotic and Flonase treatment. It is now 10 days later and the sinus infection is gone and I can breathe through my nose again. She advised that I continue with Zyrtec and Flonase through allergy season to keep my sinus issues under control. This was really scary for me to be suffering respiratory and sinus issues during the COVID pandemic. Marisa was great and I would recommend Advantage Urgent Care. THANK YOU.”
