I'm proud to introduce my nutritionist who took the time to discuss various aspects of pet food and the science of nutrition. He has been working in the field of multi-species nutrition for almost forty years with clients like The San Diego Zoo. As you watch the videos, it becomes obvious Mark has a high level of expertise and is passionate about his craft. I thank him for his time since I want anyone considering a Kumpi product to know that they are in the hands of a seasoned professional. These bring scientific clarity and give you some basic knowledge about pet food formulation and how many moving parts there are in the process. If you don't go with Kumpi, you at least have a different set of skills when considering a choice. Obviously, I hope once you have listened you will consider the Kumpi 100% buy back guarantee and realize you have nothing to lose and so very much to gain.
