My pup (Gio) and I love Alex!
Gio is now 5 months old and has been doing private training sessions with Alex. She is gentle and patient and most importantly trains me on how to best train Gio.
Gio has also stayed with Alex for a week while we were on vacation and she has the option to incorporate training with her at home dog sitting service. He learned so much during his stay, and I know he was happy there with all of the pictures sent keeping us posted on how he was doing.
Alex is very knowledgeable about different breeds and how to tailor training and behaviors for each breed. She obviously has a strong love for dogs and Gio and I love and trust her!

Top notch boarding and training! GPP is our go-to for several days or several weeks since our 7 pound puppy became 115 pounds this past year and a half. Highly recommend.

I put my 2 dobermans in 2 week Board and Train with Alex. My dogs came back completely different. They both now actually listen to me.
They learned basic obedience: sit,down, stay, leave it, focus, break. They are both now create trained and dont pull on the leash which makes walking way more enjoyable. They also use to chase bunnies, squirrels, skunks, now stare at them and dont chase the them. I dont know why I waited so long to train them.
I am also scheduling meetings with Alex for more 1 on 1 private training session to have my dobies for refreshers courses and advanced obedience. I highly recommend Alex if your looking for a dog trainer. I liked the fact that she is independent as oppose to other dog training facility that boards and trains multiple dogs since they might not get as much attention as a private independent trainer who can provide more focused training.

Alex was so great with Tofu (Goldendoodle). We ended up having her board him for 2 weeks to really work on his walking and general commands. We picked him up on Wednesday and are so happy with the results. We can walk him around the neighborhood without be pulled around and he listens to basic commands now.

Alex is an excellent dog trainer, and has a great connection with dogs. My dog was puppy crazy, and super high energy. He basically ran my life with zero discipline. Alex really helped me build a better understanding of him and guided me through training. I have a better connection with my dog, and the tools to actually lead him. It’s a complete 180 and he’s so much more composed.
