The P.E.T.S. Staff works tirelessly to implement the P.E.T.S. Mission in every task they take on. Customer service means making sure you love your visit. It also means making sure your pets are cared for like family. When it comes to your furry family members, our staff would probably take each one home if you’d let them.

Leslie Harrelson

Founder & CEO

Leslie Harrelson founded P.E.T.S. Low Cost Spay and Neuter Clinic in July of 2007. Leslie graduated from Midwestern in 2000. She is currently the President and CEO of P.E.T.S. After spending 11 years running the day to day operations of P.E.T.S., the growth of P.E.T.S. demanded that Leslie focus on larger goals for the organization. She spends her days overseeing all service and program operations while focusing on clinic growth and fundraising.

He also manages fundraising strategy, donor software, donor communications, clinic software, and tech related training for the organization. 

Lisa Pettijohn

Director of Marketing

I started as a volunteer even before P.E.T.S opened. I saw a plea from Leslie needing help with a fundraiser to get P.E.T.S. started. Knowing our community had a serious problem with pet overpopulation, I knew in my heart that P.E.T.S is where I wanted to be. Fast forward to 2015, when I was able to become the Marketing Director and Public Relations representative for P.E.T.S. Both of these involve so many different aspects, from all things marketing, to building relationships, to fundraising and to letting everyone in our community know the P.E.T.S name. If you know me, you know I absolutely love my job and couldn’t imagine being anywhere else. On a personal note, I have 5 fur-babies, 4 human children and 2 human grandchildren. The little guy pictured with me is the love of my life…the one and only Jimmy Choo.

Trixie is 14 and in the photo with me. 4 kitties: Spike, Lewis, Dilly and Loopy Fiasco.My idea of a good time is sitting by my backyard fish pond on a sunny day reading a book. I love to garden, hike any great nature area, and travel.

I’m the Development and Social Media Assistant for P.E.T.S. Pit bulls are definitely my favorite breed. I have two spoiled ones that own me. Gita a rescue and Spirit a birthday present. I  volunteer more hours than I worked because it’s just in me to help. I like making a difference in our wonderful community.

I support P.E.T.S. because I believe every animal should have a loving home and we make sure our animals in the community have just that.

Lukas Pettijohn

I have been at P.E.T.S. for a little over a year. I had volunteered previously before I got hired on. I support P.E.T.S. because what we do here is very much needed in animal welfare, and it feels good being able to make a positive impact in our community. One fact about me is that I play video games competitively in my spare time, I have reached as high as the top 1% globally in rocket league. I have 4 animals at home. Rally, Beatrice, Jimmy Choo and Manola they are all dogs.

Stephanie Floyd Bennett

I started as a volunteer in 2014 after relocating from East Texas. P.E.T.S. is so much more than a spay/neuter clinic. It allows me to take care of not only to animals but the people who love them. I could not do this w/o my family’s support. I have been married to Nick for 25 years and have 3 wonderful daughters. Lanie is at Baylor Law School, Regan is at Texas State University and Rilee is at Rider high school. I would much rather have a book in my hand than watch TV! I am also a die hard Saints fan living in Cowboy territory.

Kai Marcos Liriano

I have my Masters of Buddhist Philosophy from the University of South Wales. I’ve worked at P.E.TS. 6.5 years and support P.E.T.S. because I believe animals are awakened beings and this gives me the chance to assist their path. Fact: My pops once spit on a frogs head, sitting on a park bench, to impress a girl.

Kari Banahan

I have 6 dogs at home Buddy, Snowball, Maggie, Fred, Karma and Luna seen in this photo with me. I used to be the ACO in Electra and I am still actively involved with the animals in town. I also volunteer as a foster for dogs through TPC and UE. I am a Colorado native so I love my mountains, all 4 seasons, nature and all dogs of every breed.

Esly Pimental

I have 2 dogs. Mako is my 2 year old rescued lab seen in the photo with me. Korra is also 2 and a husky. Both were fixed at 4 months old and are 2 peas in a pod. My girlfriend Andrea is my son Liam’s mother. We both enjoy family life and our dogs. She also works with animals. I have been with P.E.T.S. for over 2 years. I was a volunteer first because of my best friend and dog Nova. When she passed 2 years ago, I promised her I would help save as many animals as I could for as long as I was breathing. P.E.T.S. is who I am!
