  • Dr. Jeff Wittman

    Dr. Jeff Wittman opened Sierra Veterinary Care in 1994, following his dream of owning and operating his own small animal hospital.  Dr. Jeff grew up in the Sonora area, attended Sonora High School and graduated as valedictorian before being selected as œRegents Scholar and going on to UC Davis, majoring in animal physiology.  He then attended and graduated from the UC Davis School of Veterinary Medicine in 1989 and was again awarded the prestigious honor of Regents Scholar.  Dr. Wittman also was SCAVMA president and served on the UC Davis School of Veterinary Medicine Strategic Planning Commission.

    Although Dr. Jeff has a background in both large and small animal medicine, his passion for small animal medicine became his focus and pursuit.  As well as running a successful practice, he has special interests in orthopedic surgery, dentistry and oral surgery.  He has also completed a fellowship at the UC Davis School of Veterinary Medicine in the area of ultrasonography.

    Dr. Jeff currently co-owns the practice with his wife, Debbie, and they have two school-age children still at home on the "Wittman Farm".  Dr. Jeff serves on the local school boards and various other committees in the community.  He enjoys watching his children participate in the local 4-H clubs where he was once a member himself.
