Meet Our Team
The talented designers at AHS architects provide expertise in architecture, planning, programming, interior design, and sustainability.
By renovating and reusing existing buildings, or designing spaces that heal or planning new places for people to work and play, AHSa designs projects that protect our environment and improve people’s lives.
Starting with the vision set forth by each client, our team designs a complete solution that best serves building owners and users. Working across markets and industries, our designers bring their experience and expertise to deliver that vision.
AHSa promotes a culture of service through volunteering, donations, and participation in organizations and events. From annual office outings for O’s games to design competitions that benefit local charities, the AHSa team strives to make an impact in our community.
