My name is Nicole Henrich. I just recently graduated from college and joined the Acacia Team. I love working with animals and enjoy caring for them. I have worked with a variety of animals and hope to possibly work with exotics again in the future. I am very excited to see where this adventure takes me!
Howdy! My name is Madison, but I prefer Madi. I was born in Mexico and before you wonder, Spanish is my first language. I immigrated to the U.S. with my mom and brother at a very young age looking for my perfect dream to chase. During my high school years, I developed a passion of rescuing broken, exotic pets from bad situations and gave them a better life. This led me to attending Carrington College only one week after graduating high school to become a Veterinary Assistant. Later on I started working with a fast paced-clinic and off-site spay and neuter for almost three years and I am now a proud member of the Acacia team! When I’m not working, I like cuddling with my two cats and having long imaginary conversations with my snake, Mr. Bubz, and I enjoy traveling to attend EDM festivals and dancing my soul away!

Dr. Olsen is a native Tucsonan, graduating from Rincon High School, and then with Honors from the University of Arizona with a Bachelor’s degree in Animal Health Science.

She and Ron enjoy world travel, scuba diving, cycling, hiking, reading, and fine food and wine. And she loves to tell stories in the exam room, many of which start as, “I remember when…”
Dr. Olsen is delighted to re-join the Acacia family on a part-time basis and is eager to meet you and your furry family members.

Brendan left the corporate world to begin working with animals as a career back in 1998.

Accepting the challenge of managing a new start-up and taking it into the future, Brendan has been here since the very start in 2010.
Brendan is a member of VECCS (Veterinary and Emergency Critical Care Society), of AAHA (American Animal Hospital Association), and he continues to work with local animal rescue/welfare groups.

Hi there! My name is Ginny and this human is my momma Janette! She always talks about how she wanted to work with animals since she was young. Out of high school she went to Pima Community College and graduated from the Veterinary Technology Program where she found me! When I got to my new home I had 2 sisters named Autumn and Noel, who mom calls ‘kitty cats.’ Recently I got a new brother named Tonic, who we call ‘Wild Man.’
Mom joined Acacia Animal Hospital in 2017 and always comes home smelling so interesting. She tells me that she works with exotics and birds but I definitely smell dogs. In mom’s free time we sometimes go hiking or visit people but mostly we play in the yard or cuddle on the couch (she tells me I’m the best cuddler). I hope your furry or non-furry baby loves her as much as I do, I know she’ll love them!
Allie is a California native who began her journey at Acacia in February 2020, after working in a small animal and exotics practice for 2 years in Virginia.

She has 2 pitbulls at home, Chance and Callie, and an axolotl. She is currently in school studying to become a licensed Veterinary Technician, and has a heavy interest in exotics, dentistry, and dermatology.

Customer Service Representatives Supervisor
Misty has always been passionate about helping animals. She has been in Tucson for about 19 years and currently attends the University of Arizona where she is pursuing a Bachelor of Science degree in Natural Resources with an emphasis on Wildlife Conservation and Management. Her free time is spent with her husband, 4 children, 2 dogs, 2 cats, snake, and hammy. She also enjoys travelling, volunteering at the Desert Museum for Raptor Free Flight and helping rehabilitate wildlife. In the future, she hopes to either become a bat biologist or help with conservation efforts through a zoo. She thinks all animals are fascinating but absolutely adores bats and raptors, and of course loves cats and dogs.
I started working with animals when I was 15 and haven’t stopped since! I grew up in Houston, Texas and came to Tucson to continue my degree in Animal Science. I hope to get into disease control and the study of genetics when I finish my degree. When I’m not at work I spend most of my time with my dog, cat, and hamster. I also enjoy hiking, camping, and road trips in my spare time.
