Hello Pet Parents! I am so excited to be joining the Old Farm Veterinary team! I have been grooming for 9 years and look forward to pampering your furry friend! I started in college as a veterinary assistant but quickly fell in love with the art of grooming. My passion has grown over the years and I look forward to this new journey with all of you. I enjoy spending time with my son and my 13 year old terrier mix, as well as playing softball and hiking. Please stop in for a day of pampering for your pet or just to introduce yourself!
