To honor both of these incredible women figures we decided to work with Jefferson Mack Metal to design a gate in memory of both of them. From the design process to the final product it was the most magical experience. I'm not very creative, but had the most fun during this process. Attached are some photos from the actual design to the prototype to the finished product. Honestly his talent is unmatched and if you are looking for a reliable company to install and design a gate, hand railing, house numbers, basically anything with iron steel you have found the right man and company.

We have a 98 year old retail space on Mission St. with an iron door in the sidewalk. The door was developing tiny holes due to rust and we didn't want it to get worse. David cut out the rusty section, removed the handle, then put the handle on a new piece of metal and welded it in place. Fantastic to work with.

The not so good?!?! Older fella came out and he didn't seem too happy to be here. He also had a hard time conveying any design ideas and requirements clearly. He had Hispanic accent which I am no stranger too. (I've worked and managed hundreds of Hispanic folk over the years) We finally came to some design and construction details but I felt like I was given a take it or leave it handrail solution. He didn't offer any other constructive solutions unlike another company I was also trying to get a quote from He did throw a price out there before leaving. So with that rough start I decided not to work any further with them. Too bad Oh well. I give them 3 stars for just not putting the best foot forward?
