"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."

"Solomon and the guys at Melo Gardens were AMAZING throughout my full front yard renovation!! I replaced my boring, water-guzzling front yard with new modern, eco-friendly landscaping (part of the Long Beach lawn-to-garden program). I couldn't be happier with my finished project! Melo gardens took care of tree trimming, poured a fresh concrete pathway, installed new irrigation, and found some really awesome plants at a reasonable price. Solomon was super attentive to my needs (and trust me, I can be needy lol). He was happy to make adjustments during the installation and also made some really great recommendations. You can tell he definitely knows what he's talking about. All my neighbors have been asking about my contractor I'm happily telling everyone about my great experience!"
