About Cedarbrook Veterinary Care

Welcome to Cedarbrook Farms

Cedarbrook Veterinary Care values our patients as family members and we provide a level of care and experience we’d 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 patients 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 patient 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.

For this reason, and for the holistic health of our animals, Cedarbrook makes the whole animal well-being a priority - not just their physical health but also how our patients 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 that connection we have formed with our patients carries them through the trauma to a healthy recovery or peaceful passing.

Cedarbrook Veterinary Care was founded by Hannah Mueller, DVM, in 2004 as a one doctor mobile practice and has grown into a multiple doctor practice with the addition of the Cedarbrook Farms facility. Cedarbrook Veterinary Care was named in honor of Dr. Hannah’s canine ‘vet school angel’ Cedar and her daughter Heron Brook. Further expansion has given the Cedarbrook Veterinary Care team the opportunity to better serve our clients and patients through holistic rehabilitation.

Our practice believes a holistic combination of possible modalities is the best way to provide cutting edge care to our patients. Traditional western medicine misses so many valuable treatment options that alternative medicine has to offer, and in many cases the root of the problem. Alternative medicine misses the leading edge of diagnostics and equally valuable medical treatment options. Rather than just considering alternative vs. traditional medicines, our ‘holistic’ practice combines the two to be truly on the forefront of what medicine has to offer. Cedarbrook fully encompasses the word holistic – it is inclusive and provides for the complete high quality care for all aspects of the whole patient — mind, body, herd, environment, nutrition, fitness, etc. The balancing of these energies for fitness/bodywork avails our vets to a higher understanding for veterinary services, bio-mechanics, physical therapy and the like. This experience and intention strengthens our veterinarian’s perception and evaluation abilities to discern both the physical and energy potential of our patients.

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 do this by paying the utmost attention to the individual needs of our patients and their guardians through compassionate care and integrity.

The Doctors

Our doctors have been and continue to be avid horse people. They have personal experience caring for and interacting with horses on a regular basis outside of their practice. This includes barn chores, physical and mental training, riding, showing, teaching and interacting with equines 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.

Hannah Mueller, DVM - Dr. Hannah is a 2004 graduate from Oregon State University College of Veterinary Medicine with a focus on equine sports medicine, lameness, advanced equine dentistry and nutrition. She has continued her studies to include acupuncture, chiropractic, physical therapy, herbs, energy work and more. Read more about Dr. Hannah...

Justine Griesenauer, DVM - 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’s 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. Read Dr. Justine's full bio...

About Dr. Hannah Mueller

Dr. Hannah Mueller is a 2004 graduate from Oregon State University, College of Veterinary Medicine. 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 resides in Snohomish, Washington with her family as well as her dog, cats and horses. She enjoys hiking, biking, guitar, dance, skiing, and of course, riding.

About Dr. Justine Griesenauer

Dr. Justine

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 does the same with 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 that 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’ll spend 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’s 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 on long runs with her Australian Shepherd mix Ruby (she completed her first marathon in spring 2018 and has run 7 half marathons!), getting lost in a good book, or exploring the trails on a hike or backpacking trip. Dr. Justine is a 2018 graduate of the University of Tennessee College of Veterinary Medicine.
