In Memoriam – Dr. David E. Lashley

For over 50 years, Dr. David E. Lashley, DVM, has owned and operated Lashley Animal Hospital with a focus on preventative, wellness, and surgical care as well as the diagnosis, treatment, and cure of sick animals. He has received repeated nominations as one of the Top Three Veterinarians in the Belleville News Democrat’s Readers Choice Awards.

Dr. Lashley gives back to his community by volunteering to teach children about domestic animals and wildlife at local elementary schools, and by serving as the founder of the Veterinary Explorer Post for the Boy Scouts of America. He also spent more than 20 years serving as the sole veterinarian for Treehouse Wildlife Center, a nonprofit organization that provides community service to people in southwestern Illinois, who encounter injured or orphaned wildlife. There, he donated his time, services, and supplies to save the lives of a wide variety of wildlife species.

Dr. Lashley has also provided Pro Bono services to the Belleville Area Humane Society, including teaming up with a colleague to donate the center’s first Avid Microchip Scanner to facilitate the return of lost pets to their owners. Additionally, he has served as the President and Vice President of the Southern Illinois Veterinary Medical Association throughout his career.

Having served as veterinarian for K-9 police units in Belleville, Cahokia, Caseyville, Sauget, and Swansea, he is often sought by the handlers and professional partners of working dogs. Dr. Lashley donated a bulletproof vest to the Village of Sauget for one of Illinois’ top performing K-9 officers and provided complimentary care to a local search-and-rescue dog who gave his life to the rescue and recovery acts following the September 11, 2001 attacks at the World Trade Center in New York City.

A 1967 graduate of the University of Illinois, College of Veterinary Medicine, Dr. Lashley was one of the first veterinarians in the United States to learn and perform a Femoral Head Ostectomy – a surgical procedure that removes the femoral head and neck from the femur to alleviate hip pain. This procedure has saved the lives of many large breed dogs who suffer from hip dysplasia.

Dr. Lashley is a Belleville, IL native and has been married to his wife Pamela for 42 years. He has three children: Christopher, Brook, and Sean; and four grandchildren: Caitlyn, Braeden, Kinsley, and Beckett. His household pets include Paddi, an Irish Setter, and Keleigh, a domestic house cat. He is also Granddad to Apollo, an English Cream Retriever who belongs to his daughter Brook, as well as Deus, a Bernese Mountain dog belonging to his son Christopher.

Dr. Hannah Tyrey

Dr. Hannah is a 2014 graduate of the University of Missouri – Columbia School of Veterinary Medicine. Originally from the greater St. Louis area, she knew she wanted to return upon graduation. She had a passion for animals from the time she could crawl.

Her undergraduate work was completed at the University of Missouri – St. Louis, so she could stay close to home and family before leaving, albeit only 2.5 hours away, for veterinary school. She currently resides in Jefferson County, Missouri with her immediate family very close by.

Dr. Hannah enjoys working with companion animals and loves all patients like they are her own. She has a particular interest in soft tissue surgery and would love to focus more on ultrasound and behavioral medicine in the future. She also enjoys teaching and mentoring those looking to get into veterinary medicine or students already enrolled in school.

When not working Dr. Hannah enjoys spending time with her 6 dogs and her Quaker parrot. She loves spending time with family and her 5 nieces and nephews. If not running around chasing and playing with family you can find her curled up with a good book.

Dr. Hannah is available to provide care to new and existing patients Monday, Tuesday, Wednesday, Friday from 9 AM to 6 PM, and every other Saturday, 8 AM to 1 PM.

Dr. Emilia Holzwarth

Dr. Holzwarth is a 2023 University of Missouri – Columbia School of Veterinary Medicine graduate. She comes from a rural town in Missouri located about an hour southwest of St. Louis. She grew up surrounded by a variety of animals and knew she wanted to stay in the Midwest after graduation. She currently resides in O’Fallon, Illinois.

Dr. Holzwarth attained a Bachelor’s of Science in Biology with a minor in Business Management from Stephens College in 2017. She took two years off after graduating to get as much clinical experience as possible before being accepted to Veterinary School in 2019.

While she appreciates all species, large and small, furry and scaly, our companion animals and horses have earned a special place in her heart. She has a special interest in preventative medicine, especially dentistry, and would love to expand her abilities to include soft tissue surgery and special imaging. She also intends to start Equine Ambulatory work after getting settled in.

When not working, Dr. Holzwarth enjoys horseback riding, spending time with her dog, two cats, a horse, and a ball python, and playing board/video games with friends and family.
