Meet Our Doctors

Julie Callahan, DVM
​ Dr. Baker grew up her entire life in the Hampstead area, playing soccer, basketball, and softball and riding horses.  She spent many hours volunteering at Manchester Veterinary Services to gain veterinary experience during her high school years.  She graduated from McDonogh School and then Virginia Tech, playing competitive soccer at both institutions.  She attended the VA-MD Regional College of Veterinary Medicine and graduated in 2004.  She has worked at Manchester Vet for the past 16 years and currently lives in Hampstead with her husband, Dr. Callahan, and their two daughters.  Her primary interests are managing patients with long term medical conditions and hospice care.

Jeff Callahan, DVM
​Dr. Jeff Callahan grew up in Baltimore County.  As long as he could remember, he always wanted to be a veterinarian.  He graduated from Towson High School and attended the University of Delaware where he fell in love with large animal medicine, working on all aspects of the college farm.  He graduated with a BS in Agriculture and went on to attend the VA-MD Regional College of Veterinary Medicine.  He graduated vet school in 2004 and started practicing large animal medicine in southern PA and north-central MD.  After 5 years of large animal work, he and his wife Dr. Baker purchased Manchester Vet, where he adopted the role of small animal vet.  Dr. Callahan's primary interests are surgery and ultrasound.  He currently lives with his wife Dr. Baker and their two children in Hampstead, and spends his free time competing in ultramarathons and obstacle course races.
