In 1987 Jim Murphy and Jay True created the partnership that we now know as JMA. The fundamental principle behind their partnership was to prove to the industry and themselves that a construction firm could be run with integrity, honesty, fairness and still be healthy and profitable. This mission was the reason that the company’s culture was founded in stewardship; truly listening to clients and sincerely putting their best interests above their own. They soon realized that this principle virtue would be the foundation of the company, the source of their strength and the inspiration behind the idea of truly being an uncommon builder.

Today the mantle is carried by Jesse Malone and Steve Ronchelli. While their formal partnership started in 2016, they have served JMA’s clients for a combined 40+ years. JMA now includes over 40 employees, all of whom share a sincere commitment to our culture of stewardship. To all of us, stewardship means we accept not only the responsibility to perform our work in the best way we know how but also placing the needs of others before our own. Construction is a collaborative process that requires paying attention to every detail. We show this by taking note of the feelings and reasons behind words spoken during client interactions, treating our clients resources with care and approaching each task with humility.

### Typical Job Cost

$2.5 million - 50 million

JMA’s new residential estate home building costs typically run $600-$1000/square foot — and as much as $1100-$1200/square foot. That’s exclusive of land, infrastructure and soft costs (architectural fees, consultant fees, permits, etc.). Our typical remodeling costs are comparable, depending upon the scope. Commercial/winery projects range so widely in scope and complexity, it is impossible to state a range here.

### All 6 reviews

**★ — HU-769980850, Oct. 2025**

> Low quality firm - mixed quality of work, missed every deadline and significantly over budget in adding to aggressive upsell and over charging

**★★★★★ — Werner Maassen, June 2017**

> “In my 30 years as an architect, I’ve never had a better experience with a general contractor. JMA’s effort was well beyond my own expectations, those shaped from years of working with contractors of all types and capabilities. From early in the design process through property management after construction completion, JMA embraced the process with quiet but effective leadership, and forward thinking in regards to both client and architect needs and desires.”

**Comment from JMA (Jim Murphy and Associates):**

> Thank you, Werner, for your kind words. It would be great to work with you again.

**★★★★★ — Stephen Juelsgaard, Feb. 2017**

> I couldn't speak more highly of Jim Murphy and Associates. Everyone I worked with from JMA were professional, knowledgable, thoughtful, friendly and service minded. The quality of construction of our new residence was excellent as was the attention to detail. Our job superintendent, Jesse Malone, was absolutely wonderful to have in charge of the project. We couldn't be happier with the end result.

**Comment from JMA (Jim Murphy and Associates):**

> Thank you for your kind words, Stephen. It has been our pleasure to serve you.

**★★★★★ — Kim Edwards, Jan. 2017**

> We used JMA because the company provides an outstanding level of quality, attention to detail and on-site personnel.  Additionally, if there is a problem even 10 years down the road, they come back and fix it.  They are a company in which the "boss", Jim Murphy, sets the culture of high integrity, quality, and honesty which results in a great home.  And they're easy to deal with.
>
> We've used them to build our home and for and addition 10 years later.

**★★★★★ — mel9361, Jan. 2017**

> We recently toured the Kistler Vineyards Trenton Roadhouse and just wanted to compliment you on an incredible restoration of the historic roadhouse. All the details are a wonderful expression of the JMA focus on quality and aesthetics. And, after a year of living in our JMA-built house we are incredibly thankful that we chose to work with the JMA team for our wonderful home.  We appreciate your craftsmanship and attention to detail every single day!

**★★★★★ — Prema Behan, July 2014**

> JMA is the absolute top of the line. I was the client rep on a construction and preservation project that they did - their attention to detail is stunning. The project included the retrofit of an adobe home that was built in 1842 and required intense precision. The outcome has been nothing short of mastery! This adobe will live in perpetuity and it retains it's historical integrity and cultural importance to Sonoma. They also came in on time which was against all odds with this property and it's scrutiny by the city and county. Job well done!

**Comment from JMA (Jim Murphy and Associates):**

> Prema,
>
> We have not met.  I am JMA's marketing manager.  The houzz.com comments/reviews/questions come to me.  Thank you for taking the time to provide a review on houzz.  And, I really appreciate your enthusiasm for the work we accomplished with you and the design and construction team.  I look forward to seeing the finished project soon and would enjoy meeting you when I do.
