Treelore

This could get contentious but I would say that the tree is slower to push on that side from stress and a reduced ability to translocate because of the loss of fibrous roots due to the cutting. The buds are still swelling and it looks as though they will and are breaking so I would suggest a bit of a nurse back to health programme. Composting of about 2-3 inches followed by Mulch of roughly the same depth out to the dripline or as far as is practicable and plenty of water. I would steer clear of any chemical fertilizers as they are apt to burn. I would also suggest a compost tea application or at the very least vertical mulching to improve the soil component. And without bagging the tree company cause I am not sure of what there objectives were but it doesn't look like a crash hot pruning job so potentially try another company preferably and organic based company obviously with recognizable certs and insurances. I am sure many others will follow with other good advice I am liable to have missed at this late hour.
