Dr. Renee Mansfield 


Dr. Mansfield grew up in a small town in New Hampshire where, from the time she was
seven, she began documenting her own dog’s health. She knew she would be a
veterinarian. While she loves all aspects of being a doctor, she finds the bond that
forms between her patient, their family, and herself the most rewarding aspect of
veterinary medicine. It is also through this bond that she feels she can be a better
advocate for her patients and attain better communication with their families.
Her educational background includes a Bachelor of Arts from the College of the Holy
Cross in Massachusetts and a Doctorate of Veterinary Medicine from Colorado State
University. Dr. Mansfield began practicing small animal medicine in 2009 at a six doctor
practice in Denver, Colorado. She moved to Vero Beach in 2013 to work at yet another
large practice. In May of 2016 she joined St. Francis Animal Hospital where she is one
of two veterinarians, and the focus is more on family.
Dr. Mansfield is a member of the American Veterinary Medical Association and the
Treasure Coast Veterinary Medical Association. She has strong interests in both
ultrasound and ophthalmology.
