Cheryl Naumann, President and Founder

Cheryl has been humanely trapping animals in Maricopa County since 2012. Her first trapping case was a dog named Roxy, a Shepherd mix who had been living along a freeway in Phoenix for several months. Cheryl has been an animal welfare leader for more than 20 years.

Cheryl and her husband, Roger, own a luxury boarding facility, Second Home Pet Resort, which opened in Phoenix 2008. She is a member of the National Animal Control Association, member and past board member of the Association for Animal Welfare Advancement, and was a founding member of the Arizona State Council of the Humane Society of the United States. Cheryl formerly served as President and CEO of the Arizona Humane Society, leader of the Maricopa County Animal Care and Control Animal Care Task Force, Chairman of the Board of Friends of Animal Care and Control (now the Arizona Pet Project), and Chair of the Arizona Companion Animal Spay/Neuter Committee.

“By day”, Cheryl serves as a human resources executive for a billion-dollar national corporation based in Phoenix, Arizona; she has been married to her husband Roger for 29 years, and she has two grown stepchildren. Their animal family includes 4 dogs and a cat. When she’s not rescuing animals, Cheryl enjoys hiking, travel and volunteering at her church.

Cheryl’s passion and specialty within HARTT is creating strategies for the most difficult-to-rescue dogs and utilizing complex specialty traps and electronics to bring animals to safety.  She is also focused on training and equipping the next generation of skilled, compassionate humane trappers so that more lives can be saved.  Twice a year, she facilitates HARTT’s humane trapping workshops – she has taught more than 400 humane trappers across the United States, and in five other countries.  

Linda Bruce, HARTT Board member

Linda Bruce has been rescuing animals for over 20 years and served on the board of Friends of Animal Care and Control (now The Arizona Pet Project) for 6 years. In 2017 Linda completed the HARTT Training class and has been volunteering with HARTT since them. Her most recent rescue was a small, terrified mom and her 5 puppies. Mom was rescued but not able to show us where she had hidden her tiny pups. In an amazing team effort, the puppies were found behind a locked concrete wall, inside of a locked small storage unit, under a wooden blanket covered with an engine. Miraculous! Mom is currently in foster and all pups have been adopted.

Linda has worked for 16 years at Fidelity National Title as AVP, Business Development. She and her husband Ron (also a huge animal advocate) have 6 dogs and 2 cats, and she enjoy hiking, traveling, biking and hanging with their pack. She is proud to join the amazing, experienced team of HARTT in pursuing her mission of “saving one life at a time”.

Mechelle Colby, Tucson Team Leader

Mechelle Colby was first introduced to HARTT through her own personal experience when her furry companion, Tucker, managed to escape from a boarding kennel and was missing for 22 days. Thankfully, her dog was rescued, and Mechelle witnessed firsthand the remarkable skills and knowledge possessed by HARTT in reuniting pets with their owners. Fueled by this experience, she is passionate and dedicated to help share her knowledge to help others reunite with their furry loved ones.

Mechelle works full time and has two beautiful children, with one getting ready to embark on the exciting journey of college life. Mechelle and her husband are proud owners of two adorable dogs named Buddy and Tucker. Whenever she has some free time, Mechelle loves to go for a run on the nearby Arizona Trail, engage in DIY projects, explore new places through travel, and most importantly, cherish moments with her family.

Traci Cook, North Central, Southeast and South Central Team Leader

Traci Cook stumbled across HARTT’s Facebook page after her sister’s dog went missing.  She learned more about dog rescue groups and immediately wanted to get involved.  In December 2018 Traci, became a volunteer at the HARTT shelter and in the spring of 2019 Traci took HARTT’s trapping class.  Since that time, she’s successfully saved many dogs, including several who have been missing for weeks or months.

Traci works full time, has two children and one beautiful grandchild. In her spare time, Traci loves to run trails with her Rhodesian Ridgebacks, Cash and Akina, and spends time with her husband, Nathan.

Charity Cox-Hayden, North Central Team Leader

Charity has been with HARTT since Fall of 2021, working in both field rescue and at the HARTT shelter. She first became interested in joining the team when she learned of the organization and the numerous animals that were successfully reunited with their owners, and the commitment to rescuing injured and emaciated stray animals. As a strong advocate for animal welfare, Charity has worked to secure and care for numerous missing and stray animals in her time with HARTT.

Charity is a Registered Nurse of more than 20 years specializing in surgical services. She presently works full-time for Atlas Healthcare Partners as the Chief Nursing Officer and maintains a board seat for the Arizona Ambulatory Surgery Center Association. When she isn’t working or volunteering for HARTT, she can be found caring for her personal rescue pack of 8 dogs and 2 cats, fostering at risk dogs, and spending time with friends.

Sheri Dreyer, Program and Communications Coordinator

Sheri has always been an animal lover!  Her pets, many of whom were strays, have included cats, dogs, horses cockatiels, rabbits, reptiles, a turtle and even a squirrel.  While attending school to earn a degree in the medical field, Sheri took a part-time job as a kennel tech for a rescue and fell in love with the work.  She earned her degree but knew that she was meant to help animals – she’s now been involved with rescue for 10 years.  Sheri previously worked for a rescue that partnered with HARTT and was amazed at the incredible dedication shown by HARTT volunteers.  When HARTT posted a full-time position, she knew she needed to apply.  Sheri has now been with HARTT since 2021 she enjoy every day of it.  Her job is diverse – she provides guidance to the public on the first critical steps to take when a pet is lost, and she routes all incoming help requests to our team leaders across the community.  She manages all of our shelter and veterinary animal records, and she assures that all of our donors are recognized for their contributions.

Sheri lives with her husband, four rescue dogs, and a cat that showed up at her door almost 20 years ago.  She also has 2 grown children and a grandpup that they raised when she was abandoned at 2 weeks old.  In her spare time, Sheri enjoys reading, knitting & taking road trips.

Donna Kelly, West Team Leader

Donna came to HARTT in August of 2019 through first-hand experience, when a very skittish Maricopa County Animal Control foster dog escaped.  She worked alongside our West team and fortunately, after 35 days on the run, “Eddie” was successfully located and humanely trapped.  And, several months later, “Eddie” became “Eddie Kelly” and was welcomed into Donna’s home.  Donna was in awe of HARTT’s processes, and the strategy and skill required to recover lost and at-risk animals and so, she decided to join our team!  After serving as a member of our West valley team for 2 years, Donna became our West Team Leader in 2021.

Donna is one busy woman!  After being raised in Phoenix and spending nearly 20 years in the hospitality and entertainment industries and managing celebrities, she decided to leverage her relationship-building skills within the real estate industry.  As a successful, high-producing real estate agent, Donna takes pride in helping her clients find the perfect home for their families.  When she’s not selling homes or trapping, Donna enjoys singing on local stages, shopping and dining out.  She shares her home with the love of her life, Brett, and her 19 year old son, Nicholas (who is also a HARTT trapper and his mom’s partner in the field!).

Eva Livesay, Northeast Team Leader and HARTT Board Member

Eva has been a volunteer with HARTT since completing her trapping workshop in 2017. She is passionate about helping all animals and most importantly getting lost dogs reunited with their owners. When she isn’t hanging lost dog flyers you can find her hiking, baking or reading. She lives in Scottsdale with her husband and 3 sons (…and 3 fur babies and 2 desert tortoises).

One of her first cases she took on for HARTT involved a brindle pittie mix that had been living on a golf course for some time. She was fairly easy to trap since she was consistently coming to the same area for her food that the maintenance workers were providing. Eva’s youngest son named her Penny because he said she looked like a copper penny. Penny was eventually adopted by a young lady that was looking for a companion that could be trained as a seizure response dog. Penny is now with her new family, living her best life ever!

Tina Wilcox, Director of Operations

Tina has always had a passion for saving animals. She joined HARTT in 2020 and after trapping a little dog, she was hooked! She had the amazing opportunity to join the HARTT staff and manage our shelter operations in September 2021.  Her responsibilities include overseeing shelter staff and volunteers, coordinating incoming animals with our volunteer team leaders, overseeing facility repairs and maintenance, and assuring that all protocols are followed for the health, safety and wellbeing of our shelter animals.

Tina has five dogs. Jazzy (Dachshund), Sammie (Pitbull mix), Porsche (Australian Shepard mix), Cactus Jack (Poodle mix), and Penny (Terrier mix).  When she’s not making life great for our shelter dogs, she loves spending time with her family, hiking and organizing!
