As a collaborative firm, we carefully build our team for each project based on the specific needs of the project. We have relationships with local engineers, planners and designers to build a strong team for any type of project.

Steven S. Hassevoort, AIA, NCARB, LEED AP

Managing Partner

Steve’s passion is making old buildings and building sites useful once again.  After 24 years with firms in Ann Arbor and Kalamazoo, he ventured out and founded InForm Architecture to allow him to pursue this passion full-time.

Steve enjoys delving into a client’s organization to make sure that  each project fits that organization’s culture and really meets its long-term needs.  With degrees in architecture and business administration (and a couple of years as a music major), he is a true generalist and relishes all aspects of a project from needs assessment, design and detailing to financing, tax credits and technology.

The best part of his job is getting a group of people really excited about their project!

Todd A. Russcher, LEED AP


Todd is our detail guy.  You may see Todd out in the field creating accurate base plans for an existing building.  You may also see him conferring with the contractor during the construction process.  Behind the scenes he coordinates with our specialized consultants and he makes sure the documents we produce are accurate and concise.

Todd also keeps our team up up-to-date on the latest technology to keep our operations smooth and efficient.  He is our BIM (Building Information Modeling) expert and the go-to guy for all things AutoCAD.

Working with the team to develop the very best solution to each challenge is what Todd enjoys most.

Mary Whittaker Duncan, R.A.


Mary is devoted to engaging with groups and organizations who make a difference in the communities in which they work.  She works diligently to understand their needs, their limitations and their opportunities.  Her involvement often begins well before a project is envisioned, and she works to bring the right people (consultants, experts, other collaborators) to the table to encourage collaboration.

A problem-solver at heart, Mary has a knack for working with diverse groups to reach consensus.   Through careful listening and thoughtful questions, she strives to uncover the core values and goals that can be embraced by all.  Very much a team player, she thoroughly enjoys collaboration with our team and our clients.

Contributing to projects that improve people’s lives is what makes Mary tick!

Hannah Knoll

Architectural Technician

Hannah handles a variety of the nitty-gritty tasks involved in projects—drawing up base plans, assembling construction documents or whatever else needs to be done. She knows details can make or break a project and is happy working behind the scenes to get everything in order.

Hannah’s also an artist (because that’s what you do with a physics degree) using acrylic painting, photography and furniture design/sculpture to examine how the structure of our physical surroundings shape human interactions and define our communities (and how communities reciprocally shape their environments). She’s also experienced in organizing and facilitating community-based art and arts-related projects, which she greatly enjoys.

Working collaboratively with others to shape and create spaces of connection within the built environment is what truly motivates her!

Amy Ragan

Interior Designer

Amy is an interior designer who strives to complete her clients’ vision by building a relationship with them, listening to their ideas, and utilizing her expertise.  Her past work experience includes residential design and wood studio design. These aid Amy in understanding how small details in a project can largely impact the end result.  Possessing creative but logical thinking in the design process allows her zeal for design to show through well-organized proposals.

Amy is full of energy and her ambition is driven by her clients’ satisfaction and confidence in her.  Her passion is to be personally involved in projects and envision beyond her clients’ desires, creating a result that exceeds their expectations.

Whether a project is big or small, Amy loves to see design and function come together to make a desirable space that is useable and unique.

Sherry McAllister

Architectural Technician

As the newest member of the InForm team, Sherry works behind the scenes on all things drawing-related. An achiever to the core, Sherry is motivated to produce documents that are timely and precise. Sherry brings 10 years of commercial architectural design experience from firms in the greater Kalamazoo area and Lansing. Because much of her previous experience is in school design, she is very excited to work on residential projects for the first time.

With 25 years of AutoCAD experience, an eagerness to take on new challenges, and a commitment to efficiency, Sherry is there to help get the work done wherever she is needed.

From field checks to punch lists, Sherry helps keep us on track!

Mitchell Curtiss


Mitchell is currently an undergraduate student at the University of Michigan enrolled in the Architecture program, but has spent the last two summers working with InForm. Although he is still learning the ins and outs of the business, Mitchell contributes on a daily basis to nearly every project that comes through the office.

Drawing up existing plans, updating construction documents, or even just helping out around the office, Mitchell is always available to help in any way the company needs. Working with InForm has been an invaluable supplement to his architectural education, and Mitchell is very grateful for his time with the firm.
