  Casey Mittemiller:

Since joining the team, Laura has learned incredibly quickly, picking up all sorts of technical skills and exhibiting both diligence and passion for working in a clinical veterinary setting. In doing do, Laura’s favorite parts of working with GTVH are the wonderful staff that she is surrounded by, the opportunity to work with a variety of patients and owners, and the ability to bring so much joy to individual people through the care of their pets. Laura loves the outdoors, and on her off time, you might see her two tracking, hunting, fishing, and hiking with her husband and dog "Charlie" (Australian Shepard). 

Erin Krysinski:

Erin Krysinski has been working with Grand Traverse Veterinary Hospital for just over four years.  As the daughter of Dr. Alexander and Dr. Krysinski, veterinary medicine has always been a large part of her life.  While growing up, she worked for many years, first as a kennel assistant and later as a veterinary technician at the family’s veterinary clinic in Detroit.  After graduating from Colgate University in 2013 with a bachelors degree in Neuroscience, she found that veterinary medicine was her true passion and spent the next year in rural central New York, working as the only veterinary assistant for an equine internal medicine specialist and surgical specialist.  When her parents purchased Grand Traverse Veterinary Hospital in 2014, she found herself back in Michigan to further expand her veterinary experiences while also applying to veterinary school.  Erin spends the majority of her off time training her ex-racehorse “Sur” in eventing, but she can also be seen doing a vast array of other outdoor activities, from mountain biking, to kayaking, fishing, hiking, and even snowboarding in the winter.  Though she is currently in her final year of Veterinary School at Michigan State University, you might still see her here helping out during breaks.

Casey Lorence:

Casey is another more experienced member of the GTVH team.  After graduating from Baker College with her LVT degree in June of 2015, she began working as a licensed veterinary technician at GTVH that fall.  Though originally from Standish, Michigan, she moved to the beautiful Traverse City area and has loved it ever since.  Since being here, she’s been able to take advantage of her surroundings by hunting, fishing, skiing, horseback riding and generally enjoying the outdoors. When she’s not playing outside, she can be found hanging out with her 2 adorable cats Socks and Marlow.

Sandy Ball:

One of our most experienced Veterinary Receptionists, Sandy has been working with GTVH for the past 9 years and since has become not only an integral part of our team, but a bit of a jack of all trades as well. Though her primary realm is up at the front check out desk, she can also be seen filling in in back when the other technicians need help. Sandy’s previous experience as an EMT has allowed her to be incredibly patient, calming, and compassionate especially in times of stress, and her warm smile welcomes all that visit. On her off days, she can be seen kayaking and spending time outdoors with her collection of furry friends: two adorable Australian cattle dogs, "Muggsie" and "Della", one cat "Mountain Lion",  and a flock of chickens. Occasionally, you’ll see Muggsie and Della hanging out behind the front desk.

Wendy Foss:

Wendy joined the GTVH team in March 2018, after having been a client for several years.  Wendy grew up on a small farm in Vermont and has always had a love for animals.  Although her life has been somewhat nomadic, she decided to put down roots in the Traverse City region, drawn to the water and woods.  When not greeting clients and pets at GTVH, leisure time will find her pursuing outdoor activities, baking, traveling to explore new areas, and walking in the woods with her one-eyed wonder dog Borts.
