That passion is also a big part of the way Spencer leads.

Julianna Bedoya Henao is part of the K9 Mania team, where she spends her days working closely with dogs and continuing to grow her experience in the training world. Being around dogs every day is something she truly enjoys, and it shows in the care and attention she brings to each one she works with.

For Juliana, dogs have a special way of lifting people up. Their energy and presence can turn a tough day into a better one. That connection is one of the reasons she loves this work so much.

Her approach to working with dogs centers on patience, observation, and genuine care. Juliana believes dogs learn best when they feel understood, so she takes time to notice what motivates each dog, whether it’s play, affection, or engagement, and uses that to keep them focused and happy during training. Because every dog is different, she adapts her approach to match the personality and needs of the dog in front of her.

Helping dogs feel calm is just as important as teaching them new skills. Juliana pays close attention to each dog’s state of mind and creates moments for them to relax, whether that means a bit of play, quiet attention, or simply allowing them to settle and reset.

Juliana has a deep love for all the dogs. This is personal. She has a tattoo in honor of her rescued dog, Kiara, who she found on the street and welcomed into her life. That experience shaped the way she sees animals and continues to remind her why caring for dogs matters so much.

Karla Stefanny Ozejo Flores brings a unique blend of technical skill and a lifelong passion for animal welfare to her work. Her connection to animals is a deep-rooted family tradition, inspired by her grandmother – a renowned Peruvian actress who currently cares for 14 senior dogs. This background provided Karla with early, firsthand experience in managing large groups and understanding the needs of aging pets, fostering a career built on compassion and responsibility.

With a year and a half of professional experience in pet grooming and hair salon care, Karla has mastered the art of animal handling and comfort. This hands-on experience allows her to maintain a calm and confident presence, ensuring that every dog feels relaxed and safe in her care.

To further her expertise, she is currently studying dog training, specifically canine behavior and handling, under the professional guidance of the instructors at K9 Mania. Her approach centers on building a foundation of trust and approaching every animal with the patience required to truly understand their behavior.

Karla believes that successful training is rooted in knowledge; she enjoys researching the origins of different breeds to better understand their natural instincts and tailor her approach to each puppy’s specific needs/ Whether she is working with her favorite breeds: the Golden Labrador, German Shepherd, and Goldendoodle, or any other variety, she ensures that every interaction is a positive and engaging learning experience. Although she is currently a proud owner of two cats rather than a dog, Karla brings that same level of devotion and professional care to every dog she assists.

Diego is a dedicated Kennel Technician at K9 Mania who brings a breeder's eye to every dog in his care. Having spent years evaluating dogs and their behavior, he knows how to read what a dog is showing him, whether that's confidence, hesitation, or something in between, and adjusts how he approaches each one so they feel comfortable and secure.

That care starts the moment he walks up to a kennel. Diego greets each dog by name, offers his hand to sniff, and gives them the space they need until they understand he means no harm. Once the leash is on and they're out for a walk, he mixes in play and gentle corrections so the dog learns that time with him is fun, while also understanding the limits.

Beyond walks and playtime, Diego makes sure every dog's daily needs are met, from proper food and fresh water to a clean kennel and a calm space to unwind.

He also has a dog of his own, a beautifully mischievous girl named Mabel Von Starkenherz, or Mabi for short. She lives back in his home country of Peru, but the moment she hears his voice, she lights up. That bond is a big part of why he treats every dog at K9 Mania like family.

Hailey is a Content Head and Kennel Technician at K9 Mania, helping keep things running both at the front desk and in the kennel. At the front, she helps keep the space clean, organized, and welcoming. In the kennel, she works hands-on with the dogs, making sure they're cared for, comfortable, and getting the attention they need throughout the day.

That's the part she enjoys most. Every dog that comes through K9 Mania is different, and Hailey loves getting to know each dog's personality, whether it's a goofy puppy or a more serious working dog. She pays attention to those little differences and brings that same care and attention to every dog she works with.

Hailey doesn't currently have any pets of her own, but working with dogs every day has given her plenty of opportunities to appreciate just how different each one can be.
