Denny Grieder


Blake Grieder

Growing up on a fun farm in Farmington, Illinois, Daren’s passion for plants and animals was nurtured by his father, who also embraced his own love and passion for the outdoors.  Daren spent two summers working in the Peoria Park Districts Youth Conservation Corps gaining experience in park maintenance, building and maintaining hiking trails, erosion control and working with the environment.  Daren pursued these passions in college and earned a B.S. and M.S. degree from Southern Illinois University in Forestry and Park and Recreation Management. He served six years in the Peoria, Illinois Air National Guard and six months active duty during Desert Storm.  At Grieder’s, Daren has the opportunity to work for a positive and forward thinking company, with people who share the same passions.  He enjoys working to provide customers with a place they can relax and know that the beautiful environment they've worked hard to create and call home stays looking that way. He has been at Grieders since 2002.

Maintenance Manager

Accounting Manager

Janet came to Grieder’s as the Accounting Manager in June 2018.  Within this role, she handles almost all aspects of the business office, including payroll and employment taxes, accounts payable and accounts receivable.  Although her background isn’t in landscaping, she has over 14 years of accounting experience working in collections, accounts receivable and accounts payable.  Janet loves the outdoors.  When weather permits, she spends time camping and fishing with her husband.  Having never fished as a kid, her husband took her fishing for the first time in 2015.  She now loves fishing and is always looking for the perfect fishing spot.  When she has time to herself, you can usually find Janet reading a book by one of her favorite authors, including Stephen King and James Patterson, or catching up on some of her favorite television shows such as NCIS, Criminal Minds, and the Walking Dead.  Or if she’s feeling creative, she’ll draw, color, or write.
