These guys were professional and courteous. The owners -- Oliver and Oscar both provided expert advice and maintained a professional--yet friendly demeanor at all times. The work team who did all of the work were equally as professional. You could really tell that they were at the top of their game. I had a really, really, really tall tree. Even though they did not have space to use a crane they were in complete control at all times. I would highly recommend their service to others. Also, I was impressed at how they kept the customer in mind..they will work with you. and provide expert advice to ensure that you make the right decision. I would suggest including O&O in your decisionmaking process. O&O came out to see the job the same day I put out a request for estimates. Their offer was unbelievable. I cancelled all other appointments. From prior experience, I knew that O&O was giving me a fair deal, any other estimate would have been too good to be true. My tree was really, really, really tall..I knew what it would require to cut it down. I'm actually grateful that O&O came by first. I lucked out. These guys and their team are superb in all aspects of the job.
