Dr. Peter Mosites


Dr. Mosites (sounds like “bronchitis”) received his DVM from Ross University in 2015, after completing his clinical year at the University of Minnesota.

He practiced for several years as an ER veterinarian in San Antonio, TX before moving to Florida to open his own relief practice Lone Wolf Veterinary Services, LLC.

He enjoys traveling, spending time with his wife Dr. Reina Hagstrom and their dogs. He also enjoys reading comic books, building LEGO, the Minnesota Vikings and telling himself that someday, he’ll take up surfing.

In addition to his work with Mermaid Vet Hospital, Dr. Mosites continues to practice as a relief veterinarian and serves as a Captain in the Army Reserve Veterinary Corps.

Dr. Reina Hagstrom


Dr. Hagstrom received her DVM from Ross University, after completing her clinical year at the Murdoch University in Western Australia.

She was born and raised in Tokyo, Japan, and moved to Idaho to complete her undergraduate degree.

Together with Dr. Mosites, she practiced several years as an ER veterinarian in San Antonio, TX before moving down to Florida.

Although not common among veterinarians, she is especially passionate about pet dental procedures and someday plans on opening a Mermaid dental clinic.

She enjoys traveling, spending time with the family, keeping up with Orange theory, and of course, transforming into a mermaid in the water!

Dr. Arizona Spencer

Dr. Arizona Spencer


Dr. Arizona Spencer earned her DVM from the University of Florida (Go Gators!), along with a professional certificate in Shelter Medicine.

As a Florida native, she is a proud “Double Gator,” having also attended UF for her undergraduate degree.

Before vet school, Dr. Spencer worked as a cardiology veterinary technician at UF’s teaching hospital. Although cardiology had stolen her heart (pun intended), she found a love for Shelter Medicine, client education, TNVR, and low-cost community services/access to care during vet school.

Dr. Spencer enjoys going to breweries and the beach with her Shih Tzu, Mocha, and her significant other, Sebastian. She also has two cats, Oliver and Samuel, along with a musk turtle named Reggie, that love it when she spends nights at home watching “trash love documentaries” on her streaming services.

Tiffany Besancon

Shift Lead

Tiffany has been a technician for 22 years and enjoys it to this day for many reasons. It is anything but monotonous… Most days you never know what’s going to happen despite what it says on the appointment schedule. She enjoys getting to help our patients grow into healthy adults, and help them when they are feeling ill.

Tiffany also takes a special interest in surgery, especially when it means correcting a problem that prolongs our 4 legged family members lives.

Outside of work, Tiffany enjoys spending time outdoors with her family. Together, they go four-wheeling, boating, camping, and host events with their land conservation chapter of NWTF (National Wildlife Turkey Federation).

Amy Yeatts

Certified Veterinary Technician

Amy obtained her Bachelor’s in Veterinary Technology from Saint Petersburg College in May 2021. She has explored various avenues within the veterinary field, having worked as a Laboratory Animal Technician at the University of Miami, as an overnight emergency technician at a 24 hour ER, as well as a clinic manager at a local non-profit animal shelter. She found her passion within general practice and non-profit work interacting with, and helping, pet parents to provide quality care for their fur babies. 


Amy was raised in Miami, Florida and moved to Sebastian in 2014 to enjoy a more laid back lifestyle closer to the beaches. When not at work, she enjoys spending time with her son, going to the beach, gardening, crafting, running, or simply relaxing at home.


At home, Amy enjoys the company of, not only her son, but their 2 dogs (Indy and Athena), 5 cats (Shark Bait, 2Sox, Iris, Vader and Red Titian) and 2 Uromastyx (Bonnie and Clyde), as well as the fish in their 2 fresh water fish tanks!


Nicole Simonetti

Veterinary Assistant

Hey, there my name is Nicole. I moved to Vero Beach in 2001 from Massachusetts. I started my animal care journey in 2013 at an all-dog boarding facility. In 2014 I gave birth to my son and ended up being a stay-at-home mom for almost a year. In 2019 I started working at a local animal shelter as a kennel tech and worked my way up to a veterinary tech.

My favorite part of my job is meeting and caring for all the fur babies and interacting with clients.

When I’m not working I enjoy spending time at the beach with my son and relaxing at home with our dog Molly who was rescued in 2017. Oh and I’m obsessed with butterflies and Dachshund!!!


Samantha Urrutia

Veterinary Assistant

Samantha has been in the veterinary field for about 4 years as a vet assistant. Helping animals get better is an honor and it makes her feel like she is contributing to society. She takes great pride in being a team player and learning new things every day.

On her day offs she enjoys spending time with her family whether going to an event or just cuddling on the couch watching a movie- she appreciates it all.

She doesn’t own any animals at the moment but your fur babies are her babies.


Megan Vanhouwe

Kennel Assistant at Orchid Island Dog Spa

Megan was raised 19 years in Vermont, then moved to FL for college. She has a Bachelor of Science in Digital Arts & Design and an Associate of Science in Computer Animation. She has always had the love and passion for animals and now gets to work with dogs everyday. To be able to grow up with dogs always around and now get to learn and grow within the pet industry is very exciting to her and she can’t wait to see where it leads her. Megan also enjoys arts & crafts, outdoor activities, photography, cooking/baking, listening to music, watching movies, learning new things, and hopes to maybe travel someday to states/countries she would like to visit.

Kennel Assistant at Orchid Island Dog Spa

I’m Sheena, I was born in Waynesboro PA but, I spent most of my time growing up in FL. I moved to Vero about 6 and a half years ago and was excited to start a new chapter in my life. I’ve always loved animals growing up with Ferrets, Cats, Turtles, Bunnies, Guinea pigs, Snakes, Frogs, Fish, Hamsters, Hedgehogs and more but most importantly DOGS! I love dogs, they’re my favorite animals. I’m a fur mom of two adopted babies my lab, pittie mix and recently I adopted him a sister that’s a hound mix. My babies are my whole world and I like to show each dog that stays at our resort the same love and attention I would want my own dogs to have. I look forward to meeting and helping each of your fur babies to have a great stay at our resort!
