About Us

Just two farmers with a dream!

Business partners Sam Andrasko and Scott brown stared in October 2017 with a dream and concept to grow specialty organic mushrooms for local farm to table restaurants and stores. 

After a lot of hard work and effort, they arrived

Sam's passion for mushrooms cannot be denied from Oyster mushrooms to Lion mane and many others the farm will strive both seasonal and year long fresh organic quality mushrooms to compliment various menus and recipes for even the most scrutinizing chefs

Local, fresh, and very tight controls

If you simply want the best mushrooms for your menu or meal...It starts and stops here at Creekside Mushroom Farms located in the east county mountains of San Diego County.
