Dr. Marissa Mueller joins Florissant Animal Hospital from Columbia, MO where she graduated from the University of Missouri with her undergraduate degree in Biochemistry in 2020 and her Doctor of Veterinary Medicine and Master of Public Health degrees in 2024.  

When Dr. Mueller isn’t treating her patients, she can be found running and exploring hiking trails or getting lost in a good book. She is looking forward to traveling and checking out as many national parks and scenic camp sites as possible in the future.  She also loves spending time and cuddling with her three cats: Belle, Robin, and Fiona.
