After nearly 30 years in the dog training business, I have decided to retire and pursue other passions in my life. But no worries, I won’t leave you without assistance! For the past few years I have been transitioning my classes and lessons over to Tasha Suda and Maria Eguren. Both are very knowledgeable and skilled dog trainers, certified and licensed and with many years of experience. I have received countless fabulous reviews about both of them from a variety of clients. I’ve worked with Tasha and Maria over the years at various occasions and have always liked their upbeat personalities and style. Please see their bios on our group class page. It is my intention to officially transfer ownership over to Tasha in early 2022.

It has been my pleasure (for the most part 🙂 ) to work with so many clients over the these past decades. Wishing you all the best!

Martina has always been an avid animal lover; before coming to America, she spent most of her summers on a farm in her native Germany, bottle-feeding calves, piglets, and anything else with four legs. She walked her neighbors’ dogs and cared for other people’s cats. When she moved to the United States in 1989, Martina immediately became interested in animal rescue organizations, and soon thereafter adopted her first dog from Peninsula Humane Society. She also started fostering newborn puppies and kittens until they were old enough to be adopted. Of course, if you’re involved in rescue work, your house is soon full of animals. Martina and her husband have lived with, at various times, six different dogs and two cats, all from various animal shelters and rescue groups. You can read about Martina’s dogs here.

Martina started training her own dogs in 1990 and quickly became involved in training other people’s dogs, just for fun. Martina began working as a volunteer dog trainer at Pets in Need, and soon realized she’d found her calling. She officially started her own training business in 1997, and has worked full-time as a dog trainer and behaviorist since then.
