Dr. Crystal Peralta

Dr. Crystal Peralta is a family physician at Square One Health Group.  She holds an Honors Bachelor of Science degree in Human Biology from the University of Toronto and also a Master of Science degree in Anatomy and Cell Biology at the University of Western Ontario. Dr. Peralta pursued her medical degree at St. Matthews University in the Cayman Islands and subsequently trained in the Family Medicine Program at Medstar Franklin Square in Baltimore, Maryland – a program and place that she holds very close to her heart. It was at Franklin Square that Dr. Peralta not only garnered the skills to evaluate, treat, and manage those from a diverse population, but more importantly allowed her to appreciate and connect with the underserved of urban Baltimore. 

Dr. Peralta believes in and practices evidence-based medicine with a focus on preventative medicine and comprehensive care. As a family physician she has a broad scope of interest and enjoys full spectrum medicine ranging from women’s health issues/prenatal care to caring for young families and even further to complex chronic disease management in older adults. Dr. Peralta is also proficient in a number of office-based procedures including joint injections, cryotherapy, IUD insertions, and minor surgeries of diagnostic, treatment and cosmetic nature. 

In her spare time she enjoys spending quality time with those she cares about—whether that’s running around and being silly with her toddler Cruz, checking out a new restaurant with her husband Bradley, taking long strolls with her puppy Franklin, or laughing the night away at a really great games night or movie night with her family and friends.
