MANDI Certified Dog Trainer/Owner

My passion for animals started when I was a small child. Research, courses, and working alongside other trainers is how I began my journey after realizing being a Veterinarian Technician was not for me. I love training, helping families find joy, and watching them succeed in a fun and positive way with their dogs. What matters more to me than my studies or my certifications, is my hands-on experience. I attribute most of my success to the thousands of dogs and handlers I have had the pleasure of working with over the years.

My goal is not only to help owners work with their dogs but to help them understand why they are doing it. That is what creates better relationships, stronger bonds, and amazing success within each dog and handler. I am building my dream team, a team of trainers who have trained their dogs with me and are now training/studying alongside me.

All Dogs is my passion. My clients on both ends of the leash, matter to me! We are not just trainers here at all dogs, We are your coaches, your cheerleaders, and your friends. Your success matters to us!

ALEX – Trainer/ Office Manager

Animals have been a huge part of Alex’s life. Over the years she has worked in the veterinary field and has been involved with different rescues. She loves all animals but says there’s something special about that bond with your canine best friend.

Alex started training with Mandi when she brought home her 8-week-old bulldog Fudge, a little 7lb meatball who started to excel. She soon realized this is what she wanted to do and started getting certifications and experiential learning. Alex is looking forward to growing with All Dogs and helping clients get a trustworthy bond with their dog.

Alex’s favourite thing to do with Fudge is agility! She just started entering him in agility trials and is also looking forward to doing some dock diving.



As long as I can remember I have loved dogs; I grew up always having dogs in my home to love and care for.

I went to school to become a Dental Hygienist but there was always a part of me that felt like I belonged around dogs. In the last couple years I have had the privilege to foster a couple rescue dogs. As a result of working with dogs that have severe behaviour difficulties, I have developed an appreciation and passion for the importance of early puppy socialization and training.

Now I’m currently working on my dog training certification with my German Shorthair Pointer (GSP) puppy. I hope to learn and grow with you and your four-legged friend at All Dogs!


Growing up with dogs, Katana always had a love for Australian Shepherds. It wasn’t until her adult years, with experience raising and loving dogs, that Katana knew she was ready for a high-energy working dog and found the perfect breeder to bring home her first Australian Shepherd; Arlo.

Arlo and Katana began training at All Dogs when Arlo was a young puppy, and their love for each other, their sense of adventure, and fun-loving dispositions set them up perfectly for dog sports. Katana is excited to introduce her love for agility to All Dogs students and hopes to see you and your dog in an agility course soon!
