Keith Larsen
Attorney Broker
Attorney, Property Manager, and Real Estate Broker proficient in residential and commercial leasing, brokerage, marketing and rent-up of new construction, and repositioning multi-family assets. As a solo legal practitioner, I've represented both tenants and landlords in legal disputes, and helped landlords and homeowners reposition their real estate assets — from resolving problem tenants to finding new ones to listing properties for sale or rent. Consider me a full-service resource for legally navigating your property management issues while achieving effective results in brokerage and marketing. Other legal experience includes closings, abatement applications, discrimination matters, consumer protection matters, contract drafting, and business agreements.
Dianne O'Connell
Sales Agent
Every project tells a story — whether it's about building homes or optimizing operations. I've spent over a decade navigating real estate and project management, finding joy in transforming ideas into tangible results. My journey began with founding DOC Management, where I learned property development while investing in luxury projects with The Heritage Companies. I believe every interaction is a chance to learn — whether managing a luxury apartment complex or overseeing software migrations at Autura, I thrive on building relationships with diverse groups of people. My background as a real estate agent has taught me the importance of understanding client needs, something I carry into every project.
