Advanced clinical ultrasound has become a standard of care in veterinary medicine and can non-invasively produce results unequaled by any other diagnostic medium.

The results are immediate and the information gleaned can greatly enhance the relationship between the general practitioner and client because of the good results the practitioner creates by enhancing diagnostic efficiency on a wide variety of cases.

Our Team

Amy Mayhew, LVT: I graduated from MSU in 2001 with a Bachelor of Science in Veterinary Technology. After working in a private practice for 2 years, I accepted a job at Oakland Veterinary Referral Services where I was employed for over 15 years. During this time, I worked very closely with Dr. Cheryl Rice in internal medicine and developed an interest in ultrasound. I completed my certificate of proficiency in soft tissue ultrasound with WAVE in December 2018. The objective of this program was to become a proficient and confident soft tissue sonographer, by immersion in soft tissue ultrasound over a 3-month period. Since this time, I’ve worked in a private practice utilizing my comprehensive abdominal ultrasound skills. In November 2020 I returned and completed my certificate of proficiency in echocardiography. I am dedicated to making these advanced diagnostic tools more readily available. In my spare time, my family and I love camping near the Great Lakes and spending time with our many rescued animals in the “Mayhew Zoo”.
