I would like to thank Marcus Curtis and Old World Mastinos for the beautiful Neapolitan Mastiff puppy we received, THANKS MARCUS, for calling and for taking the time to answer our many e-mail questions, not only do we have Cassiopeia but I feel I've gained a friend, Cheers pal. S. Robertson, Toronto, Ontario, Canada.

Since day one, Marcus has been nothing but honest, kind, knowledgeable, and very respectful. Not only does he breed world champion Neos but his customer service and willingness to take the time and help guide you through the journey of owning one of these dogs sets him apart from all other breeders. If your in the market for a puppy I would give Marcus and the Old World Mastinos a rating of 11 out of 10 stars!

Old World Mastinos, was the perfect choice in selecting a Neopolitan Mastiff breeder. Marcus is incredibly knowledgable, very helpful and truly cares about the quality and authenticity of his dogs. Marcus continues to follow up with us and is always available for any questions we may have. We absolutely love our puppy. She is beautiful, healthy and strong. We could not be happier.

I have been wanting a neapolitan mastiff for quite sometime, i looked up Old World Mastinos and talked with Marcus, i informed him about my financial situation, Marcus understood and was willing to work with me, Marcus not only was kind but he was very informative, and he not only sold me a beautiful pup he sold me the pick from the litter, i also told him that i really wanted to do the ear cropping, but i wasn't financially ready to pay for it, so he offered to pay for it for me. Marcus Curtis is not only a reputable breeder but is also i call a great friend. Thank you and God Bless you Marcus

Marcus was and Is a great person to deal with. My wife and I feel like part of a family that Marcus has put together all across America with being owners of these Wonderful massif Neopolitans. Marcus has been there for guidance throughout the entire process of our newest family member we now have "Deimos" and we could not have been blessed to have anyone else. We are looking forward to the endless smiles Deimos will bring us and can't thank Marcus enough for his years of experience with this breed making our purchase flawless and easy. Thanks again Jamie & Sylvia
