About Us

get to know us

All you want is for your project to go smoothly.

But finding the right team for the job can feel as painful as a trip to the dentist.

You’d rather put the entire thing off rather than endure the painful search for someone who truly believes in your project and wants to see it through to completion.

Is it too much to ask for a dependable, thoughtful, and responsible professional?

It shouldn’t be.

But more often than not, it can be really tough to find that needle in a haystack. Someone who will take care of the entire design process, doesn’t need hand holding, and makes sure no ball ever gets dropped.

Believe me, I know how hard it can be to find qualified professionals who will work on your behalf. There’s not a day that goes by when I’m not confronted with lack of accountability, transparency, and honesty in business.

But you know what…It’s time to quit feeling like your project will never happen because you can’t find the right person for the job, my team and I are here to help!

Hi, I’m Yolanda Lettieri.

Architecture is my passion. 

Thanks for stopping by to learn a little about what I do, why I do it, and who I love to do this for. 

My dream is to solve people’s problems with the built environment by creating spaces where there were none before.

It is my job to engage with cities, government agencies, contractors, and engineers to build what you want, so you don’t have to. But most importantly, it is my duty to make sure your building will be safe to live and thrive in, while saving you money.

YSL Architecture is a professional team committed to bringing your ideas to life, through effective collaboration, communication, and a passion for architecture and the built environment.

So if you’ve been thinking about getting a project off the ground but haven’t found the right professional to make it happen, let’s talk!

My Experience

I have nearly 20 years of experience with architecture firms, both large & small. No matter the project size, the parties involved are typically identical in structure and hierarchy, as well as how they engage with clients and project team members such as engineers, building officials, and contractors.

As an integral part of your project team, my top priority is to turn your vision into a reality. By considering all options and taking care to communicate and collaborate with the entire project team, I’m able to achieve the best results for you.

the secret to a successful project

Communication & Collaboration

Communication is crucial to every successful project, in fact, you’d be surprised at the amount of interaction and authority architects have in a project. But, at the end of the day, I work for you.

My team and I will make sure your vision is translated to other design and engineering disciplines, building officials, and contractors involved in the project so that everyone is on the same page.

your project is our

Number One Priority

As your architect, my primary job is to help you achieve your project goals so that you’re happy with the results. It doesn’t matter whether your project is a simple residential remodel, commercial tenant improvement, retrofit, or new construction.

Advocating for your interests our number one priority! My team and I will take time to walk you through the entire design and construction process, step-by-step so that you can sit back, relax, and enjoy the ride without worry.

You’ll feel pampered knowing your needs, and those of your project will be taken care of each step of the way.

how it works

My team and I will be your project advocate and protector of your dream design, and there will be no question that we will have your back each step of the way.

Your needs will be aligned with results, though the use of effective listening and communication skills to ensure we achieve clarity in the design process.

why i do this

Care & Concern

I do this because I care for our environment. There are countless opportunities for us to improve where and how we live, and I want to be a part of the solution.

My mission is to improve my community by design, one project at a time by creating a legacy of thoughtfulness, mindfulness, caring, and compassion that people need in their lives.

Design occurs when compassion, understanding, honesty and integrity are combined with people that care about building better communities for a sustainable future.

My Personal Story

My life has always been filled with change. In fact, I find creature comfort in an airplane!

I was born in Puerto Rico, but as a toddler, my Dad’s job took the family to the San Francisco Bay Area.  We moved around every few years and I attended many different schools, until the age of 13, when we moved back to Puerto Rico.

Eventually, I found my way back to the United States to attend The Pennsylvania State University, where I earned a bachelor’s degree in Architecture and soon returned to California.
