Hi there. I am Diana Foster, the founder of Assertive K-9 Training and Thinschmidt German Shepherds.

I am a born again Christian and always put God first. He is at the center of everything and has carried and blessed me all throughout my life. I thank Him every day for all that He has done. This thriving business is truly a Blessing from God, and I give Him all the praise and all the glory!

I was born and raised in Nutley N.J., a small little Italian town back East. I was the second oldest of 9 children and left home when I was 18. I moved to California when I was 25 and have lived here ever since. I have absolutely loved dogs all my life, from when I first started to walk. I am so fortunate and grateful that the Lord has allowed my passion and love for dogs to not only support me all of my life, but this amazing business that has carried many others as well.

I have trained dogs professionally for over 40 years now,  and have been breeding German Shepherds for 20 years. I love this journey that I am on and continue to learn and improve my skills and education on an on-going basis. My family has not only been very supportive, but many have joined me in this amazing business, along with very passionate employees which makes it all work and succeed. I could not be where I am today without the hard work and commitment from my family and extremely dedicated and loyal team members!

I have been blessed with 4 beautiful children and 8 gorgeous grandchildren. I absolutely love spending time with them and going places, as we always have a blast when we are together. I love them all so much and we are all very close. I also enjoy quiet times with just me and my dogs. I love the Lord, movies, shopping, theme parks, the holidays, and the beach.
