Working with Billy, Kerri and the entire crew of Derian Pools was an absolute pleasure. From the beginning of the project with Billy to the execution and completion with Kerri, the process was flawless. Their crew was always polite, responsible and punctual. We had such a great experience that we extended the scope of works to include demolition, retaining wall construction and paving over a new concrete base that they laid. The whole project was on time and on budget. I would not hesitate to recommend Derian Pools most highly!

We had a great experience working with Kerri & Billy. We live in a mid-century modern home and Billy did a great job visualizing the transformation of our back yard and then developing a plan. Then came Kerri and her great crew to make that plan happen. They are not only very professional in what they do, they are an absolute pleasure to work with. We are loving our pool with waterfall and outdoor kitchen and are very thankful for the work they did to make it happen.

Kerri of Derian Pools made the construction and installation of our pool really stress free. She and her crew were courteous and extremely professional. They offer a complete package according to one’s needs from design to finish product.

This is the second time we’ve used them and will definitely continue to use them for our future projects.

We’re highly satisfied with their work and we highly recommend them.

My wife and I really enjoyed working with Kerri, Billy and her crew on building our backyard oasis! The project was a complete success and came out amazing. They were super helpful in giving us ideas along the way and not being shy on product and color recommendations.

They were extremely hard working and quick, but had just the right amount of attention to detail where it mattered. Kerri was always extremely fast at getting back to us on any questions we had, even on a weekend. She even went the extra mile for us when we had a heater issue months after our project was completed. She handled the the whole warranty process for us and had someone out next day from the manufacture to replace the bad part.

Thanks for everything!

Most people will not recommend their contractors. None of my friends would give their worst enemies the name of their pool contractors. I will . I am actually sad in a way that our project is coming to an end. Final city inspection is tomorrow. What a joy this project of transforming my yard as been. Kerri and her team are so special. They were here every day working long hours and very clean, (since I am OCD that’s important.) They are courteous , honest and work in the time frame promised . All of Kerri”s subs are fabulous as well. Billy does the design work and has a great eye. You wont be disappointed ,they truly are wonderful, and I am picky.

Kerri McCoy of Derian Pools is the best pool designer, builder and innovator in the pool business. Her company can build in easy or difficult locations and her workmanship is flawless. She designed and built our salt water zero edge/infinity pool on time and on budget (pictured on Derian/Houzz page). She even has a crew to do a weekly pool service who are also fabulous.
Our architect recommended several other companies in addition to Derian but we made the right choice with Kerri. We recommend her and Derian Custom Pools with no hesitation and great enthusiasm.

What a pleasure to deal with Keri and her crew. They came in from the start as professionals are supposed to do. The crews where always here when they said they would be and they always did what they told me they were doing. I was always kept informed of the progress ad next step.

Armando who was the lead on the job is a gem. He would always take a moment for a question or any concerns I may have had

The best part of dealing with Derian pools is when I left a call or a text for Keri, a return call always happened.

When we decided to get a pool at our house in West Hollywood near Hollywood Hills, there was a lot of uncertainty–do we have enough space for pool, would city approve pool to be built in the front yard of our HPOZ property, and would we be able to afford it. We embarked on this project with very little knowledge of what it takes to construct a pool, cost of maintenance etc. but knew in this post-covid craziness we need a sanctuary for our two young kids. We started to lookup online and were astonished by so many homeowner’s bad experiences with inexperienced pool contractors with construction taking over 6 months and cheap materials leading to unexpected downstream repair costs. Fortunately with divine grace, we found Kerri McCoy of Custom Derian Pools! They had excellent reviews (as you can tell). Billy from sales showed up promptly, he was super knowledgeable and quickly identified all potential issues we may be facing given our situation. We got a detailed (all-inclusive) quote in writing along with 3D imagery of the pool design. City permits were submitted promptly, but approval took a while. After requiring some modification to original plans, the City approved it (yay). We didn’t need soil samples. Within a week of this approval, Kerri got the whole project rolling. She is a super-woman! Custom pools is what she does along with anything and everything that goes around it (full landscaping etc). She is very very efficient, she has a wonderful team of skilled and courteous workers. Ones the project started, it was like a clockwork…workers showed up on time, worked around the clock, knew what they were doing (without Kerri watching over them), were very courteous, and didn’t leave until the work was done. It started with demolition, then came a mini Bobcat for excavation/dig, followed by steel rebar install, and trench digging for plumbing. Every step of the way Kerri would swing by to make sure project was on time and meeting the standards. We have a number of planned city inspections and passed each one without a hitch. Gunite was the highlight of whole process since it transformed the big hole in the ground into actual concrete pool. Then came the masons. We chose edge-to-edge concrete decking around the pool which made the small space look bigger. We chose black/white “Greek Key” tiles and “cool blue” pebblesheen plaster. We now have our 25×11 heated pool with 7×5 spa and auto pool cover. We chose “black” Poolpro cover which traps heat and in summer we never have to heat the pool. Jandy pool equipment (pump, gas heater, ozone purifier, filter) is very high quality, energy efficient, quiet and all fully remote automated. Whole project took around 3 months after city approval. We got to know Kerri who is an incredibly kind and genuine person. Thanks to her we have a high-end elegantly modern pool and the whole process was exciting, painless and without surprises. We really appreciate you making this so smooth! We ABSOLUTELY LOVE IT!!!

When we purchased our home, we knew right away that we wanted to change/update a few of the areas, both interior and exterior. Being a designer myself, working with someone with innovative ideas was very important! Our first encounter with Derian Pools was with Billy the salesman and designer … he was nothing but professional, super friendly with creative ideas and easy to work with. Once we established what we would be doing to our existing garage and backyard, we were introduced to Kerri. She is super professional as well! Very thorough and knows her business like no one we have encountered. The end result of our projects were nothing short of amazing! Their crew was friendly, clean and respectful! I would recommend Derian Pools and Construction over and over again, as the projects we had done by them have given us many fun memories in our home with our family and friends. Thank you guys!

NOTE:
Projects done …
*converted existing garage into a game room/bar with exterior courtyard
*backyard was flat when we moved in – they created a huge wood deck with barbecue bar, herb garden and outdoor sink, covered spa, built in bali bed and the landscaping surrounding. Built us an outdoor vineyard room as well as fire pit area (great for our kids)

Kerri, Billy and the team are simply fantastic. It’s incredibly rare that you hire ANYONE who does what they say they will do; when they say they’ll do it and for the price originally quoted. THAT describes Derian.

My wife and I have gone through multiple construction projects so we had more than a few experiences with partners. What separates this group is not only their professionalism–every sub was above and beyond–but they were able to add creatively to our vision. What’s more, looking at their other projects, ours was on the more conservative end of the price scale. It didn’t matter. Not only did we feel we received the same attention to detail, but Kerri’s communication throughout was consistent, timely and thorough.

Give this team a call. You won’t be disappointed. (Before and after pictures are below.)

We’ve worked with a lot of contractors in fixing up our single family home, and Derian has been far and away the best. From initial design/pricing stages to project completion, everyone involved was punctual, honest, and respectful. Our pool and hardscaping project was comparatively small but we received A+ customer service and attention anyway.

Working with Kerri to coordinate the project was fantastic from start to finish. She was very communicative and made good aesthetic suggestions for the project. The construction team was easy to work with, very careful with our property, and meticulous in their work.

Kerri McCoy and BillyDerien. Amazing! Professional, timely, fabulous execution! Thank you for the transformation!

From the minute we spoke to Billy, we knew we were in competent and creative hands to help us design and create a backyard makeover! Kerri solidified any concerns with professional and calm reassurance. She came up with minor changes to not only insure the safety for my young grandchildren, but also ideas that would excite and beautify the entire project. The entire Derian crew created an entire new yard featuring a beautiful pool and spa as well as an outdoor kitchen and hardscape. Everyone we worked with were friendly, professional and took pride in their work. Kerri and her crew provided our own little backyard vacation.

Derian was rock solid from beginning to end. In spite of the world-wide shortage on just about everything you need to install a pool during the summer of 2021, they came through with high marks. The pool itself came out stunning, and we used Derian for design too. As well, the rest of the surrounding work they did (deck, hardscape, turf) was equally great. I knew we were going to love the pool. I didn’t know we’d love it THIS MUCH. Great, great job.

Kerri and Billy of Derian GC just helped my wife and I with a complete back-yard transformation which includes a pool, spa, outdoor kitchen and hardscape. They were helpful, communicative and had great advice throughout the process and their crews were friendly, professional and detail oriented. They helped us navigate the complexities of permitting and inspection and we couldn’t be happier with the end result!
