We offer a wide variety of pruning options for proper tree maintenance and health of the tree.  Our staff is well trained to remove all types and sizes of trees.  Our fleet of trucks & equipment allow us to access trees even in the most extreme locations.

Stump Grinding


We do stump grinding for trees we remove, as well as any existing stumps you may have.  Gollnick & Sons will contact Diggers Hotline before doing the work.  We have the latest equipment to grind the stump and clean up the excess grindings.

Emerald Ash Borer (EAB)

What to know about EAB (Emerald Ash Borer)


This bug has been in South Eastern Wisconsin for many years, but really started making an impact in the last couple years.  They only feed on Ash trees.  (Ash, White Ash, Green Ash)   Surprisingly they do not attack Mountain Ash trees.  Ash trees that are attacked can die within 2 - 4 years.

How you can protect your Ash Trees


Soil Injections and Trunk Injections to prevent Emerald Ash Borer have proven to be highly effective, with an over 95% success rate.  It is critical to treat you trees annually to protect them from the EAB.  Larger trees respond better with direct Trunk Injections.  We would be happy to check your Ash trees for signs of EAB and recommend a course of action.
