How We Work

We are a small team by choice. It allows us to stay involved, responsive, and invested in every project. Clients work with us directly from start to finish, with no handoffs and no confusion.

We lead the process, provide clear direction, and handle the logistics while always leaving room for collaboration. Our clients trust us because we are transparent, communicative, and genuinely care about the outcome.

Meet the Team

At O.M. Design Group, every project is shaped by a collective of thoughtful, skilled professionals who bring depth, clarity, and intention to the design process. While each team member offers a distinct perspective — from architectural insight to global sourcing expertise to decades of industry experience — we share a commitment to creating spaces that feel personal, grounded, and beautifully lived in.

Our work is built on collaboration. We listen closely, think holistically, and approach each project with a balance of creativity and precision. Whether we’re refining architectural details, curating materials, coordinating logistics, or guiding clients through the design journey, our team is united by a belief that great design is both an art and a service.

Together, we bring vision to life — thoughtfully, seamlessly, and with a deep respect for the people who call these spaces home.

The O.M. Design Group team

Trust and Transparency

Design works best when trust is established early. We are upfront about scope, process, and expectations. Projects vary widely, so pricing is never one size fits all, but clarity is always the goal.

Our relationships do not end at installation. Many of our clients continue working with us for years as their homes evolve.

In Their Words

JoEllen is simply fantastic. She understood my vision for a complete interior remodel of my home and helped me make it a reality. She did the research, sent me photos, found the materials, worked within my budget, and followed through until completion. JoEllen has the scope and reach to assist you, no matter your taste and style. JoEllen is the consummate professional. If she says she’s going to do something or be somewhere, you can count on her. I consider myself lucky to have worked with this amazing designer. Awesome customer service and awesome results!

We have had the great pleasure of working with JoEllen of O.M. Design Group for the last two years. JoEllen is a not only a highly professional designer, but also a really lovely person which immediately puts clients at ease. She has an impressive way of immediately being able to visualise the bigger picture, whatever the size and scope of the project. This is reflected in the stunning portfolio of houses she has designed across the valley.

I have had the privilege of working with JoEllen on two projects. One in AZ and the other in CT.

My Desert Mountain home needed some updating and JoEllen was respectful of the items I already owned and also understood that there was a budget in place for changes. She worked with me replacing outdated furniture, upholstery needs and accessories, pushing me a bit out of my comfort zone with great results. We totally renovated a bathroom and she had a great vision. Her contacts in the trade saved me money and provided quality work. Some of the decisions needed to be made after I had returned to CT for the summer and JoEllen was always available by email or phone. Friends that have visited since the updates have raved about the changes. My husband is also a fan!

The time had come to “do” our master bedroom. We had lots of pictures and lots of ideas, but weren’t really sure how to make it all happen. Lucky for us, we found JoEllen. JoEllen was able to take all of our thoughts and wishes and translate them into the bedroom we always wanted. At the same time we also decided that it was time to refresh our living room. Our living room had gone through a couple of transformaitons, but it just wasn’t what we really wanted. Once again, JoEllen was able to take our wishes and make them a reality. JoEllen is able to identify with her clients and to deliver their dreams. In additon, she is lots of fun to work with and to just “hang out with”. We are looking forward to finishing and refreshing several other rooms in our house. It will definitely be with JoEllen by our side!

JoEllen Sessa is not only a consummate professional but is also delightful. We hired JoEllen in 2013 to help us with a total demolition and design remodel of our Master Bedroom and Bath. She was always on top of the project and managed to work easily with all of the contractors. She came with great ideas, has impeccable taste and has an excellent eye for color and design.
We have continued to work with JoEllen on other design projects throughout our home with pleasing results. Furthermore, we have had no hesitation to recommend her to other Desert Mountain residents. She is the complete design package!

I worked with JoEllen Sessa, to re-design and redecorate my four bedroom home in Scottsdale. This project involved a major architectural, and structural redesign, as well as complete redecoration. JoEllen was both highly professional and fun to work with. She offered me a wide array of design/decorating choices, in terms of both style and price points. What I loved best is she brought great ideas and creativity to the project, but always listened to us and respected our priorities. I have worked with designers on projects at our homes in London and Sydney, and my most positive experience has been with O.M. Design Group.

JoEllen Sessa is a top-notch designer. She is talented and stays current with decorating trends attending many building and design product conventions. She listens to her clients to create and enhance their visions by introducing innovative and creative ideas. In 2023, JoEllen worked her magic during our home renovation which included extensive demolition and reconfiguration of interior spaces: kitchen, living room, dining room, bar, and master and guest baths. She melded both the contractor’s and our visions for the remodel. She clearly understood our design preferences. Her recommendations for lighting, flooring, plumbing, cabinetry, paint colors, etc., were spot on. A year later, we couldn’t be happier. JoEllen truly exceeded our expectations, and you can count on JoEllen to bring your project to an strikingly beautiful finish.
