Pet care experience

Hi, I’m Mary! I’ve always had a deep love for animals and a natural connection with them. I was born in the small town of Saint Clair, Michigan, where I grew up surrounded by dogs, cats, bunnies—and even goats and chickens! Caring for animals has always been a part of who I am. In 2014 I attended Eastern Michigan University with the dream of becoming a veterinarian, but I soon realized that seeing animals sick or in pain was too tough for me. After college, I moved to Charleston, South Carolina and started a career in real estate. In 2016, I began pet sitting on the side and quickly discovered it was what truly made me happy. In 2021, I moved to Denver, Colorado to pursue pet sitting full-time. It was one of the best decisions I’ve ever made—since moving to Littleton in 2024, I’ve truly fallen in love with this wonderful community and am eternally grateful for all of the amazing people and pets I’ve come to know here! At home, I share my life with my playful dog, Mr. Bean, our sweet cat, Buggy, and my wonderful husband, Paul, whom I met in 2023. They all bring so much joy and inspiration, and remind me every day why I’m so passionate about caring for animals. When I’m not working or hanging out with Mr. Bean and Buggy or Paul you’ll usually find me hiking, running, at the gym, or doing something creative. I’ve worked with pets of all ages and personalities, from high-energy puppies to laid-back senior dogs. I also have experience caring for cats and small animals, and I treat every pet like they’re part of my own family. My services include: * 🐾 Dog walking – perfect for getting your pup the exercise they need while you're busy or at work * 🐶🐱 Drop-in visits – for dogs, cats, or small animals; great for feeding, playtime, potty breaks, litter scooping, and some extra love * 🥾🐕 Dog hiking or running – for active pups who need more adventure, movement, and mental stimulation * 🛏️🐕 Dog boarding – providing a safe, loving home-away-from-home for your furry friend * 🐕‍🦺 Doggy daycare – fun, supervised playtime and socialization during the day Visit Length Options: * ⏱️ 15-minute visit – quick potty break, fresh food/water, and a little love * ⏰ 30-minute visit – perfect for a short walk and quality check-in * ⏱️ 45-minute visit – extra time for play, cuddles, and care * ⏰ 1-hour visit – great for walks, play, and more in-depth attention * 🕒 2-hour visit – ideal for pets who need extra company, stimulation, or senior care * 🐕‍🦺 Visits 2+ hours are considered full daycare, providing plenty of time for play, rest, and companionship * 🌙 Overnight boarding – loving care and a comfortable stay with me when you’re away overnight or longer Whether your pet needs a quick check-in or some extended one-on-one time, I’ll make sure they feel safe, happy, and loved every time I visit.

We had never had anyone outside of family dog sit our senior dog before so we were a little nervous about how he would do, but we couldn’t have asked for anyone better to care for him! Mary was so patient and compassionate in caring for our dog. We could tell from the daily pictures and updates that he was a happy boy.
