It wasn’t until 2002 that that she began her career in specialty and emergency medicine. While spending her time in emergency medicine, she found that she had a love for long-term client relationships and chronic illness and made the move to Internal Medicine in 2006, where she remained until 2013. She acquired her Veterinary Technician Specialty in Small Animal Internal Medicine in 2010. She also spent a year working in the Neurology service from 2013-2014. She is an active member in the Academy of Internal Medicine Veterinary Technicians (AIMVT), and serves her academy in helping to mentor new and upcoming members in their application process, as well as serves on the application committee. She is also a member of the Michigan Association of Veterinary Technicians (MAVT) and National Association of Veterinary Technicians in America (NAVTA). 
She joined the team at Oakland Veterinary Referral Services in 2014. She started her journey with the OVRS family in the ER Department, then made the transition once again to the Internal Medicine Department where she started up a new doctor department and worked with another one of their double boarded Internists/Cardiologists. During this time, she learned how much she loves diagnostic imaging and made the transition to the newest department - Diagnostic Imaging Department in the Fall of 2017 and plans to pursue her VTS in this area of interest as well. She also serves as a Continuing Education Coordinator for the staff at OVRS. 
She truly believes in making our four-legged family members as comfortable as possible when in her hands and became Fear Free Certified in 2018. 
Her interests include all aspects of Internal Medicine, Neurology, Endoscopy, Advanced Imaging and protecting the well-being of her patients. She still helps out in ER and loves the thrill of the fast-paced ER room as well. She thoroughly enjoys the case involvement the diagnostic imaging department has in the hospital and loves following up with cases of all kinds. She still does relief work for general practice as time permits. 
She enjoys spending time with her husband and two children. She also has 3 dogs (a Pug, a “Pom-Chi” and a “Golden-Doodle”) and 1 cat (Scottish Fold).  In her spare time (when she finds the time!) she enjoys bike riding, kayaking, hiking, gardening, reading, watching movies, craft projects that never get completed and relaxing!
