About Cedarbrook Veterinary Care


Welcome to Cedarbrook Farms

Cedarbrook Veterinary Care, founded in 2004, values our patients as family members and we provide a level of care and experience we would wish for with our own horses and companion animals, as well as ourselves.

Our doctors understand horse psychology and we use low stress, compassionate training and handling techniques which help our patients understand that we are here to help.

When we work together with you, the client, as a team we can reduce the amount of sedation needed for procedures, such as dental floats and minor surgeries, while improving the safety of the procedures for both your horse and doctor.

Stress can lead to immune system suppression, slower healing times and ultimately poor treatment results, whereas love, compassion and understanding can improve these things. We are mindful of this in every aspect of our patients' treatment plan; minimizing stress is key to obtaining optimal healing.

Cedarbrook Veterinary Care makes whole animal well-being a priority - not just their physical health but also how they experience their vet care. We pride ourselves on the fact that "vet phobic" horses and dogs get less and less vet phobic in our care and eventually come to trust and appreciate us. What a difference this makes in an emergency situation when connections formed with your animal (our patient) carries them through the trauma to a healthy recovery or peaceful passing.


Our Mission

At Cedarbrook Veterinary Care we strive to maximize the quality of life for our patients by providing quality holistic veterinary health care.

We pay the utmost attention to the individual needs of our patients and their guardians with compassionate care and integrity.

We are professional equine veterinarians providing friendly and knowledgeable horsecare for Snohomish, King, and surrounding counties.


The Doctors

We have been and continue to be avid horse people. We have personal experience caring for and interacting with horses on a regular basis outside of work.

This includes barn chores, physical and mental training, riding, showing, teaching and interacting with horses in a connected manner rather than simply considering them to be only a means to an end.

This actual hands-on lifestyle is not only why we are passionate about what we do, it is why we do it so well! It is vital to the essence of our practice and our ability to connect with our patients and clients.

About Dr. Hannah Mueller

From 4-H to the Intercollegiate riding team, she has loved, cared for, ridden and trained horses for most of her life; horses are her passion. Before becoming a veterinarian, she gained experienced as a veterinary assistant, horse trainer, and farrier.

During veterinary school, Dr. Hannah focused on equine sports medicine, lameness, advanced equine dentistry and nutrition. Dr. Hannah was also active in the alternative medicine club and obtained Reiki Level I and II training outside of vet school.

After graduating from veterinary school, Dr. Hannah worked first as an associate veterinarian, then in December of 2004, she started her own practice based out of Monroe, WA. Dr. Hannah continued her studies of herbs and physical therapy, as well as becoming certified in veterinary acupuncture in 2005 and chiropractic in 2006.

Dr. Hannah discovered her gift and love of hands-on healing, rehabilitation, and equine dentistry as she mastered these modalities. In 2010, Dr. Hannah opened the pristine Cedarbrook Farms rehabilitation center facility, where patients can haul in for dental floats, bodywork and other appointments, or come and stay for a few weeks to a few months for a rehabilitation treatment plan.

Dr. Hannah strives to provide the best care possible for her patients and believes her unique holistic approach allows her to do so. Dr. Hannah has a solid foundation in western medicine, dentistry, sports medicine, and lameness. This, along with her training in acupuncture, chiropractic, stretch exercises, massage techniques and other hands on healing modalities, allows Dr. Hannah to rehabilitate horses to their fullest potential. She excels in rehabilitating horses with dental imbalances, lameness, neck and back injuries, and horses with behavioral problems.

Dr. Hannah believes in following holistic principles not only in her practice but also in her daily life. She feels that stewardship to animals, the environment, and to her community is a key element of holistic living. She has a driven, passionate desire to make a difference to all the animals in her care.

Because of this passion and the need to give back, Dr. Hannah also runs Cedarbrook Farms where she enjoys giving talks and teaching veterinary and veterinary technician students how to perform veterinary procedures while providing veterinary care and rehabilitation for rescue horses. Dr. Hannah also regularly writes articles, gives 4-H and Pony Club talks, helps to manage the Equine Facilitated Mental Health and Learning program, and teaches Yoga for Horses classes at the farm.

Dr. Hannah Mueller is a 2004 graduate from Oregon State University, College of Veterinary Medicine.

Dr. Justine

About Dr. Justine Griesenauer

You have your horse to ride, for companionship, to show, to enjoy the lifestyle they bring. Your horse is important to you, as it is for Dr. Justine Griesenauer (pronounced "Grease-in-hour").

When Dr. Justine was sick enough to need a medical doctor, she appreciated the MD took time with the exam; Dr. Justine provides the same compassionate care for your horse, whether for a routine check-up, a dental float, or an emergency colic.

As a lifelong rider and horsewoman, Dr. Justine knows how important your horse is and this is reflected in her care.

Dr. Justine enjoys a good game of Scrabble, but she makes it a point to not use high value Scrabble words to discuss your horse's diagnosis or treatment (but all bets are off during the game!). While colic care, laminitis, or Cushing's disease are everyday for Dr. Justine, she remembers her first year of vet school, how confusing different diseases could be. She spends her time writing up thorough but understandable notes and treatment plans for you about your horse.

Dr. Justine learned to ride Morgan horses as a child in central Connecticut, but she doesn't know your horse like you do. She will ask for your input and seek your opinion in order to provide the best care for your horse. There is nothing like working together as a team to accomplish the same goal, and this is the mindset she brings to every horse she looks after.

When not working as a vet, Dr. Justine spends her free time getting lost in a good book, on long runs with her Australian Shepherd mix Ruby (she completed her first marathon in spring 2018 and has run 7 half marathons), or exploring the mountains on a hiking, rock climbing, or backpacking trip with her fiance, Brad.

Dr. Justine is a 2018 graduate of the University of Tennessee College of Veterinary Medicine and is a licensed veterinarian in the State of Washington.
