Kate Fisher, CRNP

Kate Fisher, CRNP oversees Occupational Medicine Services at Liberty Urgent Care.

Her passion for both patient care and workplace safety stems from her father who is a Philadelphia Police Officer and now suffers from occupational exposures due to the 9/11 attacks in New York, where he responded and assisted. This makes her the perfect match for this role.

Kate attended DeSales University in Allentown and graduated with honors with a BSN degree in 2009. She then began working in long term care, specifically taking care of subacute ventilator patients. This sparked her desire to expand her knowledge base and she became a Nurse Practitioner, graduating from Gwynedd Mercy University in 2014, again with honors. She is currently enrolled in Johns Hopkins University’s Certificate in Occupational and Environmental Health program, with an anticipated completion in June of 2017, and plans to take the certification to become a Certified Occupational Health Nurse as soon as she completes the program.

Kate believes that everyone deserves to be in a safe work environment. She loves the challenge of treating work injuries when they do occur and works with employers and employees to minimize lost work days and expenses. She brings her passion to Liberty Urgent Care and is designing the program around these principles.

When not at Liberty Urgent Care, Kate enjoys spending time baking and decorating cakes and candy, reading, and raising her two golden retrievers, Cody and Tully.

Kristin Avallon, RT

Kristin Avallon is a Radiology Technologist at Liberty Urgent Care. For as long as she can remember, she wanted to be an X-ray tech. Her father works for Temple Orthopedics and Sports Medicine, and her childhood visits to the practice on “Take Your Daughter To Work Day” instilled an early interest in the X-ray room. She also has multiple X-ray/Radiology Technologists in her family, further influencing her career choice.

Kristin graduated from Drexel University’s Radiology Program in 2015 and began working full-time at an orthopedic office in Sellersville. She joined the Liberty team last year and we are so happy to have her! She is continuing her professional development and is currently in training for Mammography.

Kristin is the youngest of 3 children. She has two brothers, one is a Philadelphia Firefighter and the other one is a CPA. Her 2 nieces and nephew mean everything to her. Kristin also has a black cat named Jimmy, named after my favorite Phillies baseball player, Jimmy Rollins. In her free time, Kristin enjoys binge-watching Grey’s Anatomy.
