Our reviews
Giving Back to Our Community
For over a century, Casper Sippel Electric has been more than an electrical contractor — we are proud members of the communities we serve. From supporting local schools to lighting up holiday traditions, giving back has always been part of who we are.
OCA Annual Tree Lighting
Sippel Electric has donated the spotlights and the 50-foot tree lights installation for the annual OCA tree lighting event since it started in 2014. We install all of the electrical work needed to bring electricity to the tree and included a switch to turn the lights on. The lighted tree and event have become a much-loved holiday tradition in our community.
Maryland School for the Blind
At the Maryland School for the Blind (MSB), located at our western boundary since 1907, a road is named Sippel Lane in honor of all that Casper Sippel has contributed to the school. In 1977, Sippel funded the construction of a much-needed indoor aqua therapy pool for the students. The pool building, visible along Taylor Avenue, is named the Casper G. Sippel Aquatic Center — a lasting testament to our commitment to supporting those in need.
