drs-anna-owren-fayne-jan-cailles-and-john-heidgerdDr. Janisse Cailles and Dr. Anna Owren Fayne met in 1999 when they worked together at Animerge – emergency medicine being of high interest to them both – and Long Valley Veterinary Hospital.

The two women found that their style, work ethic, and dedication were in perfect sync, and their personalities complemented each other well. The dream of practicing together took root.

When Dr. Cailles opened her two-doctor hospital in 2009, Dr. Owren Fayne became her natural choice as second doctor and colleague. Oldwick Animal Hospital has become a wonderful environment for them to provide the professional, compassionate care in which they believe.

To maintain this level of care, and increase convenience for our clients, Dr. John Heidgerd joined our medical team in the spring of 2013. Dr. Cailles and Dr. Heidgerd have been friends and colleagues for over twenty years, having worked together at Martinsville Veterinary Hospital in the 1990’s.

Realizing that times and methodologies were changing, Dr. Kerry Scholz was added to the team in 2016 as an on-call consultant specializing in integrative medicine, allowing us to offer acupuncture to our patients, which has been a truly remarkable addition to our treatment repertoire.

Focused on keeping up with progress in the medical field, we are thrilled to add Dr. Lauren Semanchik to our team.  Dr. Semanchik has worked at Oldwick Animal Hospital since she was a local high school student with an interest in veterinary medicine.  Dr. Cailles appreciated Lauren’s talent and has been delighted to mentor her throughout her college and veterinary school years. We are excited to welcome her home and proud to introduce her as our newest veterinarian.  Having Dr. Semanchik on board exposes us to the advancements occurring in medicine and surgery and allows us to increase appointment availability, while remaining true to our vision of having two doctors seeing appointments daily.

Our professional team is enhanced by each of these doctors.  By drawing upon the strengths and insights of each, we create a solid foundation for all, and an opportunity for every client to find the connection that each pet and owner hopes for.
