Two decades of design and construction across South America and China — now bringing that craft to homes across Maryland.
Maincare Services was founded in Maryland by Jeronimo Betancur — a Colombian-licensed architect with an international career spanning residential and large-scale projects across South America and China. Over twelve years in Beijing with the German engineering firm Obermeyer and his own studio, Equilibrium Architecture, Jeronimo led the design and delivery of roughly thirty projects in fifteen Chinese cities — from a winning entry in the international competition for the 2008 Beijing Olympics indoor stadium to the Beijing ABP Shopping Mall Complex (北京总部基地), now built and operating.
Back in Colombia, as Team Leader at Findeter, he supervised the delivery of approximately one thousand low-income homes through Housing Ministry programs across the country, managing schedules, budgets, and design compliance across ten to twelve concurrent projects each year.
Beyond architecture, Jeronimo holds a postgraduate specialization (Especialización) in Urban Law from Colombia — a credential that has translated directly into U.S. land-use practice. Since relocating to Maryland, he has guided clients through the full regulatory pathway on real Maryland projects: a Montgomery County residential variance and permit retrofit closed in 2023, and a multi-discipline commercial tenant improvement permitted by Prince George's County in early 2024 — both handled end to end, bilingual English and Spanish, no attorney required.
Jeronimo brings the rigor of formal architectural training, two decades of built work, and a regulatory toolkit honed across two legal systems to every Maincare project — from a first-time homeowner's bathroom remodel to a full coastal addition or a commercial tenant fit-out.
Jeronimo is a licensed architect in Colombia and is not currently licensed as an architect in the United States. U.S. architectural licensure with NCARB is in progress. Maincare Services operates as a residential design and design-build studio; where a professional seal is legally required, work is coordinated with a licensed Maryland design professional. Maincare Services is not a law firm and does not provide legal advice.
What you get with Maincare: the attention to detail of a boutique design practice, the coordination of a builder, and the cultural care of a team that treats every home like it's their own. We take on a small number of residential projects each year — so every conversation is direct, and every project gets the depth it deserves.
Great building starts with careful design — proportion, light, sequence, and how the space is used day to day.
You'll always know where your project stands — what's done, what's next, what it costs, and why.
Materials, finishes, fasteners, and fit-and-finish all matter. Coastal Maryland is unforgiving; the details earn their keep.
Every project is a chance to make daily life a little better — quieter mornings, brighter rooms, easier hosting.
