As a tenant in a Cornerstone-managed building, I have to say that they're the best! I have never been so happy with maintenance staff in my 2+ decades of renting apartments. I live at Carona Court in Capitol Hill and today Michael came by to replace a light fixture...he's the best. Always lovely and has excellent attention to detail. I'm heartbroken that the portfolios are being reorganized and Michael won't be working in our building anymore. I have faith that others will do a wonderful job as well. more »

Joe S. came by to work on my radiator and did a great job, as usual. I can't say enough nice things about Joe. I am very grateful for all his help. more »

Joe S. came out a week ago to install a new kitchen blind and came back today to sand the spackle where the window was damaged. Also, he changed out a receptacle in my bathroom which he did quickly and efficiently. However, as I put something away under my sink I realized there were 3 inches of water in the boxes that held my kitchen cleaners, so he quickly fixed that. I had an architect's lamp that I couldn't put back into its box and Joe did that for me which was not required of him. He did it just to be nice and helpful. He is excellent at his job and one of the nicest people I have worked with at Cornerstone. I hope management appreciates him as much as I do. more »

I have lived at Wheatly Flats since the end of August 2017 and it has been great! I had a couple of minor maintenance issues in the past month (broken dishwasher, trouble with thermostat) but they were fixed the same day by Jared who is great! My dog even likes him and she is pretty picky. more »

The management over at The Glenwood has been phenomenal. I also want to take a second to really thank Daryl and Daniel the tech guys for The Glenwood, these guys are amazing. They both were so professional, receptive and knowledgeable and they catered to every single one of my service requests. These guys are rockstars and I feel like they’re an asset to cornerstone. Daryl was the one who noticed the condition of our stove and thanks to him, we got a brand new one! He also helped us with installing extra fire alarms which were a request I made and he did it without flinching. I also would like it bring to your guys attention of how Daniel went above and beyond to provide exceptional customer service. When he removed the old stove, there was trash left from old tenants, it was in really bad shape, It was both shocking and disappointing really. I offered to help Daniel clean up the mess left behind but he insisted that it was not my duty to clean this up and he rushed to get cleaning supplies. He then proceeded to clean the entire kitchen floor and left it spotless. Not only did he have to un-install, remove and take out all the old appliances, he also installed the new ones. It was a bit disappointing that Daniel had to deal with this but he is truly an awesome person. I do not know many people who would have cleaned and stayed so polite and professional during the entire thing. more »

Our building property management changed from RedPeak to Cornerstone in 2017 and we’ve been very impressed with Cornerstone compared to RedPeak. Maintenance is superb (bravo Michael!) and problems/inquiries are dealt with quickly. Our only lingering concerns are with the storage units in the basement, which are repeatedly broken into... Cornerstone doesn’t seem to take this recurring problem as seriously as we’d like. more »

Antonio Encinas is a great maintenance technician. Helped me out when I was in a bind- my key was stuck in the lock and I had to take a final in an hour. Got everything done in less than 5 minutes. Thank you, Antonio! more »

Judd did a great job of quickly finding and fixing a leaking drain pipe behind our wall that was causing water to drip from the bathroom ceiling. He had to cut out part of the wall and ceiling to fix it. When he was done it looked as good as new. more »

Big thanks to Judd and Son, part of the maintenance team at the Cornerstone property Tamai Tower at Sakura Square (Downtown Denver). They fixed a difficult plumbing issue and were very accommodating for the brief time we weren't able to use our bath/shower. Judd provided us with a good alternative option. The maintenance team here has always been very responsive to any issues. more »

Rubin (maintenance tech) was such a great help. He assessed some minor damage that the other techs said needed to be replaced completely, and determined that the damage was minor and would just need some small repairs. Saved me some money and I cannot be more thankful for how effective he was. more »

The property management company of our apartment recent changed hands to Cornerstone, and we are SO thankful it did. Cornerstone is everything you could want in a management company; they are courteous, professional, and they work hard to make sure their tenants are happy ones. Any time we've had an issue, Ted (our property manager), responds promptly, and the maintenance tech, Michael Creech, is thorough and provides great customer service. Thank you! more »

Amazing customer service!! I locked myself out of my apartment while I was about to leave for the airport and Calley on the phone was so kind and understanding of the situation and my panic! She called back in less than a minute telling me Mark was on his way to let me in and was there in less than 5 minutes! So amazing and so helpful. I hope they get some props for their incredible help today :) more »

I have lived with Cornerstone in 3 different properties in a 5 year span. Every time there was an issue, it was handled fast and professionally. That leaves a lot of interactions with multiple employees.
My property was taken over by a different mgmt team, and it makes me miss Cornerstone even more.
Once my lease is up, I'll definitely go back to them.

Many of the reviews you will see online about Cornerstone typically comes from residents and their satisfaction with them as a property management company. My tenure with Cornerstone was short, but it made a lasting impact on me both professionally and personally, and I wanted to write about my experience working with Cornerstone.

I came across Cornerstone’s online posting for a new office admin January 2017. I was drawn to apply because I noticed upon researching online, that Cornerstone was rated 4.9/5.0 which is quite the feat for a property management company in Denver. Soon, I came in to interview with Amanda, Calley, and Courtney later to have a follow up interview with the president, Jim Lorenzen. It was a quick interview process, and Amanda, Calley, and Courtney all did a great job in laying out the expectations for my role and answering my questions about company culture. In my 2nd interview with Jim, I just knew that I truly did come across a remarkable place when he told me about the founding of Cornerstone.... why he created this business, his vision for it & his employees… it’s a story you don’t hear often and quite inspiring/admirable. I had never worked in this industry before but knew I had probably landed at the best of the best after hearing Cornerstone's vision.

In my 90 days, every department went out of their way to make me feel like a part of the team and help me in my training period. Never did anyone hesitate to help, and every day I came into an office of smiling faces and people happy to show up to work. Cornerstone employees are passionate about what they do and who they serve. Recently Cornerstone was named one of the best places to work by the DenverPost. There are companies who pay to be featured on lists like the Fortune500 but Cornerstone has truly earned its title for best place to work because of the amazing people and culture that makes up Cornerstone. If you are considering applying, DO IT!
