Dr. Lori Hageman, DVM

Just six years after receiving her education from the University of California School of Veterinary Medicine – DVM and gaining some valuable veterinarian experience, Dr. Hageman decided to pursue her dream of opening up her own veterinary hospital. It was in 1999 that she opened up the doors of The Ark Pet Hospital, Inc. This year marks her 21st year practicing veterinary medicine in East Contra Costa County.

An active member of the American Veterinary Medical Association (AVMA), California Veterinary Medical Association (CVMA) and the Association of Reptile and Amphibian Veterinarians (ARAV), Dr. Hageman likes to keep herself busy in and out of the animal hospital. She’s also the past President of the Contra Costa Veterinary Medical Association (CCVMA). One of her many passions is teaching and giving back to her community, so she has served on the Small Animal Advisory Board for the Teaching Hospital at the UCD Veterinary School and is on the Board of Trustees for the Oakland Zoo.

Dr. Hageman has a special interest in surgical cases and has taught at the UC Davis School of Veterinary Medicine in the Student Surgery department. Dr. Hageman, her husband John, and their children Mallory and Lucas live locally and share their home with 1 dog, 2 cats and 3 tortoises. When she’s not at the hospital, Dr. Hageman is at the racetrack or in her craft shop. She’s been driving cars on the big tracks for 12 years and has raced at Laguna Seca, Infineon Raceway, Sebring International Raceway and other nationally recognized tracks. Dr. Hageman welcomes you to The Ark Pet Hospital and looks forward to helping care for your family.

Dr. Don Schlange, DVM

I graduated from U.C. Davis in 1993 and immediately started working in Antioch. After 21 years I still can not imagine doing anything else. My passion has always been in general medicine but I have special interests in Diagnostic Ultrasonography, Dentistry, and surgery.

I live with my beautiful wife and two step daughters. Currently we have 5 cats (Oscar, Gary, Soot, Lex, and Lou), and 12 Geckos. Anybody interested in a baby crested gecko? 😉 My favorite hobbies are spending time with my family, mountain biking, camping, tennis, and taking care of all the geckos.

Francesca B, RVT

I’ve been part of the Ark family for 11 years. When I lived in California, I was the Ark’s lead technician, but since moving to the pacific northwest in 2019, I have now stepped into the practice management role.

Whenever I’m not working, I’m typically out hiking, at a dog sporting event, or nose deep in a book while cuddling with our cats. I also have a big interest in pet photography, so you’ll typically find me behind the lens taking photos of our two huskies Blaze and Stella, and our German Shepherd Jax.

Alora M, RVT

I have been a Registered Veterinary Technician since 1999. I met my husband and his son in 2004 and we married in 2006. I originally came to The Ark Pet Hospital in 2005 but left shortly after my second son was born in 2013. I missed my Ark family and had the opportunity to return in 2020. I am excited to be working with Dr. Hageman again!

My husband and I raise our boys out in the country and we breed Nigerian Dwarf goats. We enjoy our chickens and peacocks talking to us every morning and evening. On the weekends, we are often glamping in the national forests. We are so happy to stay rooted in the Brentwood and Antioch area.

I have always wanted to be a vet tech, there has never been a back up plan! Outside of Ark, I am active in my rescue work. I am happily married with 3 kids, all of which were and are still home schooled. We have 2 Shelties, Hopper and Loki. And a” few” cats!

Hannah A.

I’m Hannah, I’ve been a technician for about 5 years now. I’ve been in the US for 9 years as I’m originally from England. I spent 3 years in Saudi Arabia and I’ve learned so much about animals and different cultures, making me love them more daily! I have a German Shepherd “Cashew” and a 1 year old cat “Pepper” who I absolutely adore. It’s fair to say shepherds are my breed.

Tessa O.

Tessa recently joined the Ark family. When not assisting you with your pet’s needs, she’s a part time student and full time pet mom to a dog, a snake, several fish and a recently rescued chameleon. In her free time she loves to read, bake and spend time with her family and friends (pre-COVID).

Mallory D.

I have been working at the Ark since 2017. I love working with animals and I really like helping people! I have a golden retriever and 2 cats. When I’m not working or studying I love reading and binge-watching old television shows.

Lizzie J.

Hi! I’m Lizzie and I joined Ark just over a month ago and am so happy to be a part of this hospital! I’m currently in my third year of college at Azusa Pacific University where I’m studying Biblical Studies and Ancient Languages. I have 2 kitties, Magic who’s pictured here and Pepper who wasn’t feeling like getting in the picture that day. In my spare time I love listening to and making music, watching movies, and spending as much time as possible with my family and friends.

Carmen S, RVT

I have been in the vet field since 2015, starting as an intern and working my way up to an RVT. I have always loved animals and knew I needed to work with them and care for them. I have 3 dogs, 5 cats and 5 chickens that are all loved very much and make up my fur-mily.
