Pawsitive Dawg

Providing your dog with exercise, mental stimulation, and play s


Michael and his wife, Angela, both grew up in Waltham, Massachusetts.  They have always had a love for animals. Working with animals has always been their dream. They both grew up with cats and dogs and currently have two dogs – a husky mix, named Hugo and a lab mix, named Oki. They love to be in nature and go on hikes with their dogs.


Michael was a union carpenter for over 10 years and decided to change his career. He worked in a doggie day care for almost two years gaining valuable experience working with hundreds of dogs, learning all about the different breeds and their temperaments. He loved working with the dogs so much that he realized he found his true calling in life. After always working for someone else, Michael decided to follow his heart and turn his love for animals into a full time career. Nothing makes him happier than being outside with his four-legged friends!

Dog Walker

Maria has always been a lover of dogs. Since she was allergic from a young age, she was never able to have any of her own. However, her best childhood friend had a golden retriever that they both took care of for about 10 years. During that time, she learned the responsibilities that come with taking care of a dog. Despite being allergic, Maria's love for dogs outweighs the actual effect they have on her at times (very mild) and she still plans to have her own one day. Maria studied psychology in undergraduate school, providing her with the skills to build trust and the tools for creating a relaxed and safe environment. These skills come in handy when working with all furry friends!
