In 2015, Katie decided to put her knowledge to use by pursuing a career in working with animals! She began as a grooming assistant in 2013 and fell in love with the field.

Marketing & Communications Specialist
Alex grew up in Maryland and had a love and fascination for all animals from the beginning. Her professional pet-care career path started in 2016. She worked front desk at a boarding facility for a couple years before making the jump into the world of veterinary care. Alex fell more in love with the field when she stumbled upon the new Harmony Animal Hospital and learned about Fear Free methods for the first time.

Alex was hired by Harmony during their first year of business in July of 2020. She held the title of lead CSR and worked hard to keep the front desk running for almost 2 years while also managing our social media pages.

Customer Service Representative
Born and raised in eastern Kansas, Caitlin had a passion for helping animals, and learning about their health, since she was 5-6 years old. She graduated from Kansas State University in 2009 with a bachelor’s in Animal Science, with plans to continue on to vet school. When this didn’t work out due to health issues, she turned to admin work for a while. Caitlin later decided to get back into veterinary clinics since she was being asked a lot of pet health questions and realized it was still her passion. She decided to come back to the field as support staff instead (both as assistant and CSR) because she feels it has the best of both worlds when it comes to interacting with the pet and pet parent. She has years of experience in both general practice and emergency care.

She spent some time living in California, where she met her husband in 2016 when he was stationed at Vandenberg AFB. Due to her husband’s active military duty, they moved to Nebraska and lived there for a few years. Now they have moved here to Virginia, where we were thrilled to have Caitlin join our CSR team in July of 2022. She is is a Fear Free certified professional and currently going to go back to school to get her master’s in animal health and behavior. Caitlin loves arts & crafts, watching football, hanging out, and doing fun activities with her husband. She and her husband enjoy sightseeing, winery tours, zoo trips, and of course raising their beautiful daughter together!

Gabby grew up in Woodbridge, VA. Her love of animals combined with her motivation to learn more about medicine is what originally drove her to the veterinary field. She joined the Harmony team as a CSR in October of 2023 and became a Fear Free Certified Professional shortly after. She is currently in school for civil engineering and is also working towards being a veterinary technician one day. She loves being in veterinary medicine because we are a voice for the pets.

Gabby enjoys hiking, kayaking, and playing the violin in her spare time. She has an energetic border collie mix named Yasper and a sassy old tabby named Minina.



Miriam was born and raised in the Northern Virginia area. She attended Northern Virginia Community College and George Mason University where she obtained her associate’s degree in general studies and then her B.S. in Biology. Miriam has always had a passion for working with animals. Her first work experience caring for animals was as a dog daycare attendant.

Growing up in Southern Nevada in a family of animal lovers, Tamari developed a deep affection for animals early on. Her grandfather’s diverse collection of animals, including pigeons, sheep, goats, and emus, provided her with cherished memories and a passion for caring for them. She often found herself getting into trouble with her parents for trying to care for the animal babies.

Given her love for animals, it’s no surprise that veterinary medicine has been a perfect fit for Tamari. Putting her best self forward in this field is all she aspires to do. Tamari joined our Harmony team during the Summer of 2023 as a veterinary assistant and is actively pursuing her dream of obtaining certification in veterinary technology. This step will allow her to further contribute to the well-being of animals and enhance her professional expertise. She also has graciously stepped-up to take charge of the feline boarding we offer here at Harmony.

Beyond her veterinary pursuits, you can find Tamari enjoying the great outdoors with her corgi mix, Ollie. Spending quality time with him brings her joy and relaxation. Additionally, she has a passion for creative expression, and finds solace in experimenting with various artistic mediums.

Tamari is excited about her journey in the veterinary field and the opportunity to make a positive impact on the lives of animals. She believes that her dedication, love for animals, and commitment to personal growth will drive her towards achieving her goals. Tamari is a Fear Free Certified Professional.



Johanna was born in Maine, but moved with her family to the Big Bend region in Texas when she was 9. After 16 years of living in the desert, she decided it was time to start the next chapter in her life, and settled on Virginia.

Johanna started working with animals when she was 10, volunteering in a shelter’s neonatal kitten and feral cat program. She started working with horses and therapeutic riding around that time as well, then started showing horses in 4H as a teenager. She wanted to go into equine rehabilitation, but after working in a shelter after high school, she fell in love with canine behavioral health. She invested time in the behavior program and found a passion for outreach and support in communities with fewer resources. Giving animals and people compassion is a core value of hers.

While in the shelter world, Johanna was a part of medical, behavioral, and committee outreach teams. She also became deeply invested in community education. At one point, Johanna wanted to explore other species, since she had only worked with cats, dogs, and horses. She had the opportunity to intern at a HSUS rescue ranch to work with a wide variety of wildlife, including tigers, bears and chimps, but still found herself being called back to companion animals.

Johanna joined our Harmony team during the Summer of 2023 as a veterinary assistant and is a Fear Free Certified Professional. She wants to pursue a career in canine behavior, with a focus on strengthening communication, trust, and the bond between pets and their guardians. She currently offers “Cooperative Care” appointments at Harmony where she works with patients to help them overcome specific veterinary fears through cooperative care training!

In her spare time, she enjoys spending time with her border/aussie named Ada and her chiweenie named Cheese. She also enjoys backpacking, cycling, exploring museums and art installations, as well as contradancing.



Megan was a student of Virginia Tech where she graduated in 2021 with a degree in Animal Science. Following graduation, she became an assistant at a veterinary dental specialist in New Jersey where she gained lots of valuable experience.

In 2023, she relocated to Alexandria to be with her fiancé, merging her passion for animal care with personal pursuits. Megan joined our Harmony team in August of 2023 and became a Fear Free Certified Professional.

Megan adores her lizard, Rex, and her Australian Shepherd, Rogan. They both add so much joy and companionship to her life. She has plans to start school in the fall of 2024 to work towards becoming a licensed veterinary technician.



Shurada comes to us from Washington, DC. Growing up, she didn’t even know that veterinary hospitals existed but would often bring home animals off the streets as a child. At 19 years old, a veterinary assistant job fell into her lap and the rest is history. She has been in the field since 2004 and joined our Harmony team in November of 2023 as an assistant. Shurada is now a Fear Free Certified Professional. Once she is able to finish her BBA degree she hopes to go back to school for a veterinary technician license. The reason she is in this field is because she loves taking care of animals while learning new things since medicine is always growing and changing.

Shurada lives a busy life as a mom, a student, and an employee so she doesn’t have much room for hobbies right now. In her spare time, when she is not studying, she enjoys watching Asian TV and spending time with her daughter. She also shares her home with a sphynx cat named Akari and a yorkie-poo named Naomi.



Marina was born and raised in Okinawa, Japan.

She moved to the United States in 2017 when her husband was stationed in North Carolina. Shortly after moving to the U.S., they adopted a dog named Kaiji. When Marina had to take Kaiji to the vet office she could barely understand so she started using a dictionary to translate all of Kaiji’s medical records to understand his medical issues. This is what lead Marina to have interest in veterinary medicine.

Her pet care career path started in 2019. She worked at a pet store in Japan when she went back home for several months. Later that year, she started working as a veterinary assistant at a small veterinary clinic in North Carolina.

A few years later, Marina and her husband moved to Hawaii, where she continued to work as a veterinary assistant on Oahu. After enjoying tropical weather and a beach bum life for a little over 2 years, they moved to Virginia. Marina joined the Harmony team in December of 2023, and became a Fear Free Certified Professional. She’s currently taking a veterinary technician program at Penn Foster to gain more knowledge to better serve the patients and clients.

In her free time, Marina enjoys spending quality time with her husband, her dog Kaiji, and her cat Gigi. Marina loves traveling, snorkeling, hiking, pottery, exploring new places, and trying new food.


Facility Coordinator
Lee’s passion for animals has existed as long as she has. Several of the first photos taken of her included ducks, cats, donkeys, horses, dogs, snakes, lizards, and even snails! Not because she had them while growing up, but because nature always finds a way. That passion has continued through her profession, her many fosters and rescues, and her participation in citizen science projects through the Audubon Association and Cornell University. Her other passions for history, art, and global politics developed while living and traveling throughout the US and Europe as an Army Brat.

She’s never afraid to look beyond her immediate surroundings for information on interesting things, which is how she first encountered Fear Free care and Force Free training methods for animals. She’s curated her life to combine all of her passions- working in practice committed to Fear Free processes, living in a diverse community, drawing people’s pets for charity auctions, and continuing to learn new things by traveling to places that are both familiar and new.

Lee has been on our team since October of 2021 and is a Fear-Free certified professional.

Meet our Harmony Specialists!

Dr Emari Yokota, DVM, CVA, ACVCHM

From before the time she could remember Dr. Yokota has had a passion to heal animals. She learned the value of holistic medicines from her mother, whose interest in naturopathic remedies opened her eyes to the value of non-conventional medicines at a very young age.

Only after her own cat, Midnight, began to have issues with severe arthritis, did she realize the potential impact she could have on her future patients with holistic therapies. After completing her undergraduate degree at Virginia Tech , Dr. Yokota enrolled at the University of Florida College of Veterinary Medicine because of their high quality holistic program and relationship to the Chi Institute of Chinese Medicine . While enrolled in vet school, she studied and received her certification in veterinary acupuncture. Soon after, she earned her Advanced Certification in Veterinary Chinese Herbal Medicine from the International Veterinary Acupuncture Society (IVAS).

After practicing in the Northern Virginia area for over 7 years, Dr. Yokota founded Well Whiskers to concentrate on offering much needed holistic care to pets. Harmony partnered with Dr. Yokota in 2020 to provide acupuncture and holistic medicine options to our patients. Working together with our veterinarians, she continuously strives to find the best aspects of both Western and Eastern medicines to find the best care for her patients. Dr. Yokota is a Fear Free Certified Professional.


Acupressure and Massage Therapist

Raquel grew up in Washington State and has had a passion for the well-being of animals since before she can remember. She was always seeking out animals in need of a little extra TLC, from volunteering in rescues to wildlife tracking with Conservation Northwest. From a very young age, Raquel was able to understand the needs of animals by interpreting their energy, body language, and vocal cues. Her Aunt, an alternative healing practitioner for humans, provided Raquel with guidance, as she navigated the world of holistic healing. This helped her gain a strong understanding of herself and her connection with animals.

It wasn’t until her dog KC was diagnosed with Osteosarcoma and given a diagnosis of three months to live, that Raquel turned for support to a well-known acupuncturist in the Seattle area. A three-month diagnosis turned into over two additional years of joy and companionship with her girl, KC. 

After KC passed in 2019, Raquel’s passion for looking after the well-being of animals (and their humans) was reignited and she made a decision to educate herself and obtain certification in animal bodywork. She attended the Northwest School of Animal Massage where she received her advanced certification in animal massage in 2021 and certification in animal acupressure in 2023. She began her Massage, Acupressure, and Human/Animal Bonding practice to help bring balance and harmony into this world, as KCs acupuncturist did for her and her girl.

In addition to her bodywork certifications Raquel has been serving the animal community as a caretaker, dog trainer, and foster parent for over 15 years, and in 2023 she became a Fear-Free Certified Professional.

In her free time, Raquel enjoys traveling, yoga/pilates, hiking with her cattle dog mix (Einstein), reading, creative endeavors, and learning from the new and amazing people she meets.

She has worked in the field since 2008, and has experience in a number of areas including general practice, mobile practice, exotics, oncology (about seven years) and most recently hospice and palliative care.

After joining the Harmony team in 2021, Erica became Fear Free Certified and is a Certified Compassion Fatigue Professional as well. She completed the CAETA (The Companion Animal Euthanasia Training Academy) Master Training Program in euthanasia best practices and end of life care. She is currently finishing an extensive certification program through IAAHPC (The International Association for Animal Hospice and Palliative Care) in hospice, palliative care and advanced pain management, which requires over 140 hours of hospice specific education and training.

Erica is excited to be developing Harmony’s hospice and palliative care service and will be working closely with Drs Fowler, Kuo and Hagner, to ensure that patients receiving hospice or palliative care- and their families- will have their needs met and be supported throughout this difficult process. Erica also has a B.A. in Environmental Studies and a minor in writing.

In her free time she enjoys being outdoors, gardening, reading, writing, visiting National Parks, cooking, traveling, and relaxing with a nice whiskey.
