John Olson
Founding Partner + Advisor
extension 262

John was born in central Minnesota somewhere west of Lake Woebegon. His parents put him on a train to college in 1960 where he discovered Boston weather was incredibly mild, so he stayed. He now lives in Manchester by the Sea in a 1900 vintage carriage house with his wife Jane and a ragdoll cat. They are currently proudly following their daughter Alex’s career as an artist.

As a Sputnick era high school grad, he planned on going into Physics. John’s physics career ended after the first day of calculus, so he pursued his lifelong interest in architecture. He graduated from Harvard with a Bachelor’s Degree in Visual Studies, a Master of Architecture and a Master of Architecture in Urban Design. After graduating, he joined Stull Associates for 12 years working on multifamily and elderly housing and public schools.

In 1980, John founded the firm which soon became Olson Lewis. Beginning with hospitality projects for Sonesta Hotels, the firm expanded into residential, educational and life sciences areas of expertise.

He has been an avid golfer since the age of 10. Collecting is also a hobby. Collections over the years have included robots especially Gobots, an antique rose collection, a Swedish glass collection, golf and tennis sportscards from the 1920’s and 1930’s and contemporary art that fills the carriage house.

John is still actively working on OL+ projects.

Art Dioli
extension 254

Originally from the Berkshires in Western Massachusetts, Art and his wife, Betsy, are longtime residents of Ipswich MA.

Arts first interest was in construction, and he gained his Bachelor of Science in Building Construction Management at Utica College of Syracuse University, Utica, NY, and he then went on to complete his Master of Architecture in Ohio.

The combination of design and construction skills have given Art a deep understanding of the construction process and designing within its parameters.

Art and Chris first met when they both attended Miami University in Ohio. Some years later they coincidently ended up living in the same small town on the Northshore of Boston. After re-connecting, Chris also got a job at OL+ where Art had been working since 1984, and the rest is history!

Art and Betsy sold their family home of 30 years - an antique from 1740, located in this historic district of Ipswich - and downsized, buying a ‘summer cottage’ a few miles away, on Little Neck in Ipswich.

One of Arts favorite projects has been the design of their brand new home on the existing footprint of the cottage. This beautiful shingle style house is packed with modern amenities, including heat!

As well as playing soccer, Art also coached his kid's soccer and lacrosse teams for many years. He continues to ‘walk the sidelines’ supporting his daughter, who now coaches teams at a university level. He now plays in the ‘over-the-hill’ soccer league!

He has grandchildren who live locally and bring the Dioli’s much joy whether they visit the beachside cottage or the summer lake home in Maine.
Chris Doktor

Many of his projects include facilities for the Academics, Arts, Athletics, Science, and more recently for Innovation and Collaboration.

Melli is a southern belle who arrived as a puppy from an Arkansas shelter in 2019.

She comes to the office everyday with Art and can be quite enthusiastic, even boisterous at times! Being young, she tends to lose focus, forgetting to follow commands as she bounces around thoroughly enjoying her life!

She attends doggie day care a few mornings a week, playing non-stop with her friends. When she gets back to the office she barely has the energy to say hello to anyone, and just sleeps for the rest of the day!

Melli is delightful to be around. She brings a a cheeriness to the office, greeting everyone as though they are the most special person ever!
