Our Story

New Brand

September 2015 - to better reflect the leadership team and diverse staff, the company was renamed to JOHNSON NATHAN STROHE.

New Principals

Liz McDonald was made Principal and Tom Current, Associate Principal/Business Manager.

Union Station Project

The Crawford Hotel is part of the $54 million transformation of the historic Union Station in the heart of downtown Denver. The hotel has received many national awards and recognized on Forbes’ Top 10 Hotels in the World.

New Partnership

Nicole Nathan and Tobias Strohe purchased ownership stakes in the firm. They represent the birth of a second-generation firm that has grown organically and earned a strong reputation.

JGJA moves to LoDo

In 2012, the firm moved to our current address at 1600 Wynkoop Street, drawing creative inspiration and energy from the heart of LoDo.

First Interiors Project

Metro State Springhill Suites was a milestone project and opened the door to interior design for the firm. We continue to receive referrals from this important project.

JGJA Interiors is born

In 2008, the firm expanded its services and added Interior Design. JGJA was looking to further influence the design of the spaces we create; offering interiors services was a natural next step.

First Project with Dana Crawford

Jack Kerouac Lofts was a significant urban infill project for JGJA. It won a 2005 Colorado AIA Design Merit Award and a 2005 Denver AIA People’s Choice Award. It also began a lasting relationship with Dana Crawford, one of Denver’s greatest forces in historic preservation.

Aspen St. Regis Hotel

This project was a major renovation of a 5-star hotel for Starwood Hotels, our first national client. It was also our first mountain resort hotel, and the spa design was recognized in American Spa Magazine.

Nicole Nathan joins the firm

In 2002, Nicole joined the team as a junior designer. At the time of her interview, JGJA was working on a project for the National Sports Center for the Disabled and Nicole was particularly intrigued based on her long-time volunteer work with the NCSD in Winter Park.

New Identity

In 1999, the firm’s branding was changed to represent the firm’s conscious decision to focus as niche experts in hospitality and housing design.

First Project With Sage Hospitality

Completed in 1999, the Marriott Courtyard hotel in San Diego was the beginning of a synergistic, multi-decade relationship with Sage Hospitality. This award-winning project was a renovation of the former San Diego Savings & Trust Building into a boutique hotel.

JGJA moves to Equitable Building

The Equitable Building was designed in 1892 by Andrews, Jacque and Rantoul of Boston as one of Denver’s first electrified buildings. The firm’s move reflected its interest in the re-use of historic buildings. Over the years, JGJA completed several renovations to the office to accommodate the firm’s growing size, and the firm won its first Denver AIA award for the space.

Tobias Strohe joins the firm

The son of a German architect and a cabinet maker, Tobias moved to Colorado and joined the firm as intern architect after graduating from architecture school in Germany.

Hotel Monaco

This was the first boutique hotel project in downtown Denver, and JGJA’s first project downtown, first historic adaptive re-use/tax credit project, and first national client.

Palomino Park Project

This was the firm’s first large-scale commercial project: a 30,000 SF clubhouse for a 1,800 unit apartment community in Highlands Ranch.

JGJA moves to Larimer Square

In 1996, JGJA moved from downtown Littleton to 1415 Larimer Street in Denver. Jim had always loved working in downtown Denver and was ready to be immersed in the growing business environment and surrounded by inspirational buildings.

First Project as JGJA

The firm’s first project was a 4,300 SF custom residence located on the second green of the golf course at Pinehurst Country Club.

JG Johnson Architects is born

After gaining unique insight to the hospitality industry through working for a hotel company and several architectural firms in the 80s, Jim Johnson started his own company in 1993.

The French Residence

In 1983, Jim designed a 4,500 SF custom house for Mr. David French at the Denver Country Club.

Breckenridge Sports Pavilion

Completed in 1982, Jim designed the Pavilion building for the town of Breckenridge, his first project as J. Gilbert Johnson Architect, the first generation of his own firm (‘81-’84).

The Beginning of an Era

In 1974, Jim Johnson earned his bachelor’s degree in environmental design from the University of Colorado in Boulder, followed by a master of architecture in 1978.

Culture and Values


We believe that great solutions stem from curiosity - by questioning assumptions and continually asking ourselves what we can do better. In keeping an open eye and mind, we look for new and varied sources of inspiration.


We seek to understand and be mindful of the goals, interests, needs and values of our clients and potential clients. We thus aim to share a purpose, enhancing a team approach to projects while challenging each other to excel.


We deliver projects for our clients that create value measured in both financial (occupancy, rents, per-key value) and societal (impact on context, sustainability) terms. Our design and execution enhance the financial value to the client while our strong civic responsibility attends to the long-term impact on the environment and community.
