As neoplasia is part of our daily practice, we would like to introduce Julia Buchholz, DVM, Dr.med.vet, DipACVR (Rad Onc), DipECVDI (add Rad Onc) who is now available for virtual oncology consultations.

When you are informed as to the most current treatments available, you can help your clients assess their options, instead of, or prior to referral.
