About Weinmayr-Jay Assoc. Inc.

Weinmayr and Jay

Weinmayr/Jay Associates was established in 1969 by Michael Weinmayr – one of the last employees of the Olmsted Brothers firm. With roots that stem back to Frederick Law Olmsted, “the father of landscape architecture” himself, this distinctive foundation has led us to serve hundreds of clients over the past 50+ years.

Awards & Honors for Landscape Design

We are proud to have received numerous honors and awards for our landscape designs, including: planned unit developments and cluster subdivisions, healthcare facilities, eldercare facilities, parks, playgrounds, public housing renovations, private residences, commercial, institutional, and historic sites.

Weinmayr/Jay Background

As a Fellow of the American Society of Landscape Architects, Michael Weinmayr specialized in behavior modification through site design in public housing renovations. He was also particularly dedicated to maximizing the healing power of gardens at health and eldercare facilities.

David Jay, ASLA, LEED AP O+M, joined the firm in 1988, adding expertise in sustainability and historic work. He achieved the role of Principal of Weinmayr/Jay Assoc. in 2004 and assumed full control on Michael's passing in 2012.


Our philosophy is to listen. To understand each client’s desired site improvements, budget, aesthetic, and timeline so we can design a maintainable landscape that meets or exceeds all expectations. To ensure the decision-making process is as seamless as possible, we offer several schematic options for the general organization of the site. We also make suggestions on materials selections, the predominant forms for paved surfaces, and the general character of the plantings.


As one of the most experienced commercial landscape design firms in the area, we deliver on-point landscape architectural plans that lead to faster approvals, reduced time to market, and a higher return on your investment. Having been in the commercial landscape design business for over 50 years, odds are we have successfully completed a project just like yours.

Health Care & Elder Care

It is proven that a pleasant, stress-free environment can promote healing when a patient is brought to a moderate state of relaxation. Maximizing this healing power of gardens and outdoor spaces through landscape design is a unique specialty at Weinmayr/Jay Associates. Through the years, we have developed a learned understanding of the mindset and limitations of the elderly and infirmed that enables us to design safe and comfortable spaces that invoke the soothing stimulation of the senses.
Healing Garden design by Weinmayr/Jay Landscape Architects


One of the greatest challenges when working on the architectural design of historic properties is meeting accessibility requirements without compromising the historic integrity of the structure and its landscape. After a thorough review of the interior and exterior of the building, we outline any limitations on grading and architectural modifications. We then explore all feasible options and determine the best course of action – one that is up-to-code, safeguards the integrity of the space, meets all client criteria, and results in a beautifully renewed outdoor space.

We achieve this by carefully listening to your vision, property requirements, desired level of maintenance, and style preferences. We then review the natural assets of your site and draw on our expertise to develop three schematic design options that will transform your outdoor living area into your own personal oasis.
