Syndication is an effective way for investors to pool their financial and intellectual resources to invest in properties and projects much bigger than they could afford or manage on their own. Projects are funded by investors by allocating a percentage ownership based on capital contributed. Properties are acquired when fully funded, and also using leveraged financing when required. Owners receive quarterly distributions based on net income and a preferred return. Hold periods are 5-7 years, where investors also share in the equity appreciation through a capital event like refinance or other disposition of the property. Also, syndication allows investors to diversify into real estate (or self storage) without putting a majority of their personal investment portfolio into a singular investment.
We’ve built a track record of delivering great returns for our investors built on trust in our team and personal approach. Our commitment to promoting the best investment vehicle out there is anchored on our reputation of providing a comprehensive system and platform to make self storage investing as simple and accessible as possible for everyone.

After transitioning into real estate as a side business in 2012, Sergio partnered with his wife Corinn to start Hearthfire Holdings, a boutique real estate investment and property management company. In just eight short years, Hearthfire Holdings has built a portfolio of more than $50M in assets under management and syndicated over $12M in assets, returning more than $2M in profit and 25 percent IRR to investors. Property types have spanned small multi-family, commercial, retail, and self-storage properties. Sergio has also flipped houses and rehabbed properties and multi-family developments.
Sergio began his career in 1994 working in the U.S. Federal Reserve System (FRS). During his 22+ years there, he worked his way up the corporate ladder in all facets of technology, including network engineering, information security, project management and architecture, and strategy. Sergio has worked on projects and implemented systems across the banking and financial industries, with budgets of more than $100M. Notable projects include implementing secure email, mobile strategy for the division of Banking Supervision and Regulation and enterprise collaboration for the entire Federal Reserve System.
In 2015, Sergio was promoted to officer in charge of technology strategy for the Treasury Services Division of the FRS. He developed a strategy to consolidate enterprise storage and enhance treasury operations and support. His experience, IT skills, and ability to navigate the corporate ladder have given Sergio the foundation to build a real estate business and scale it through strong systems, processes, and data analytics.

Sergio and Corinn have been married since 2014 and live in Downingtown, PA. They’re proud parents of their beautiful four-year old daughter Stella. In his not-so-free time, Sergio enjoys RV camping, hiking, skiing, cooking, BBQ, gardening, technology and tinkering, traveling, and self-improvement.
Corinn’s transition into real estate began in 2012. As an individual investor, she acquired a triplex in Philadelphia’s Francisville neighborhood. The purchase was closely followed by additional acquisitions within a few very busy years—acquired initially through syndication with close family and friends. Corinn jumped into her new roles as owner and property manager across a quickly growing portfolio. After navigating a few investment property purchases, landlording, and tackling repairs and maintenance with her now-husband Sergio, the couple knew a formal partnership—in life and business—was in order.
Corinn Altomare is a classically trained musician turned real estate investor. During her professional career as an opera singer, she performed a diverse range of repertoire spanning the baroque period to contemporary, from pop-up locations in city centers to reverent chapels nestled within European countrysides. After spending 13 years as a vagabond musician, however, Corinn was ready for a new challenge. That’s when she found real estate.
Corinn comes from entrepreneurial parents—her mother founded and ran a Montessori preschool, and her father established a family and financial planning law practice. Corinn’s youngest childhood memories are of accompanying her parents on their daily entrepreneurial adventures. This early exposure served Corinn well as she pivoted to the realm of IT project management for five years. In this world, which was vastly different from her previous artistic and entrepreneurial pursuits, Corinn spent her time in growth, training, and development.
After seven years in residential real estate, Hearthfire Holdings made a strategic pivot into self-storage. This decision was based largely on the state of the overheated, overextended market and the recognition of an impending downward correction. As it turns out, this decision came at the perfect time—the COVID-19 pandemic disrupted the global economy in 1Q2020.
Pre-planning for this shift began in 2017, and Hearthfire Holdings sold off smaller syndications 4Q2018-1Q2019. Funds from these sales were consolidated into a successful acquisition of a 25,000 NRSQFT self-storage facility in Lancaster County, PA in 3Q2019.

Mark McGuire is a lifelong student of the school of hard knocks, taking the road less traveled. He’s unconcerned with academic accolades and Greek affiliations—what you see is what you get. While Mark excelled in academics at both the high school and collegiate levels, he discovered his preferred method of learning is immersion. Real-life mistakes can’t be taught from a textbook. Time and time again, Mark has found that rolling up his sleeves and getting in the trenches is the only way to truly understand something.
In 2008, Mark graduated from high school in the top eight percent of his class. He continued his academic pursuits at Temple University’s Fox School of Business. Mark never graduated from college because his curiosity got the best of him. He dropped out of school to pursue a career in music. The running joke in his family is that he went to college for three semesters nonconsecutively. From 2010-2014 Mark’s band climbed the musical ladder and opened for renowned musical acts, playing at acclaimed music festivals across the country. When Mark wasn’t writing, recording, touring, or performing, he worked a day job in property management.
The disparity between performing for sold-out crowds and plunging toilets kept him grounded. After seven years of relentlessly pursuing a music career through sheer grit, will, and determination, Mark’s band got a recording contract with RCA Records in 2014, but the terms weren’t right. Mark was given a choice: accept weak offer terms or pivot and reinvent himself.
That’s when Mark plunged into real estate sales. After running hard on his own for three years, working 80-100-hour weeks, Mark realized he needed help. He transitioned his real estate practice to Keller Williams in 2017 to learn how to build a real estate business. He hired and fired agents, learned from his mistakes, and then re-hired all over again with a new perspective. Since 2013, Mark and his team have brokered more than 300 homes with a total sales volume exceeding $83M.
Mark’s biggest passion is wealth building and investing. He is a limited partner in six syndications, ranging from multifamily to industrial, hospitality to self-storage. He has invested in multiple private companies in the biotech, finance, and AI spaces. In addition, he currently owns 20 residential units in various real estate partnerships and oversees the management of 130 residential units his family owns. Mark has also executed multiple 1031 exchanges. He’s seen up-markets and down-markets and discovered opportunities in both.

When he’s not overseeing existing investments or vetting new opportunities, Mark can be found snowboarding, fishing, or playing basketball. He also enjoys exploring new places with his wife Leah and his golden doodle Mochi. Mark loves taking things apart to understand how they work. He enjoys listening to podcasts, reading books, and sharpening his axe to perform at a higher level across all aspects of his life.
Isaac Rothermel is an entrepreneur at heart who has poured countless hours into understanding the intricacies of real estate finance and market analysis. He has worked as an employee, advisor, and owner of real estate asset types ranging from single-family rental portfolios to self-storage to institutional apartment and student housing properties. He has a deep passion for urban planning.
Isaac’s first formal job in the real estate industry was as a property manager for a portfolio of 200+ residential and retail units in York, PA. Since Isaac had no formal training in property management, his boss dropped a copy of Property Management for Dummies on his desk on the first day, along with three evictions to be filed.
After working in property management, Isaac accepted a role as an analyst for the dominant self-storage brokerage in the Mid-Atlantic region. While there, he underwrote hundreds of self-storage properties, completed more than 150 supply and demand studies for new development and more than a dozen extensive feasibility studies, and listed six self-storage properties in four months as a licensed salesperson.
Isaac then took a role in institutional student housing as a debt and equity structuring associate, where he analyzed more than $26 billion in real estate assets. He participated in large transactions including assisting Greystar with its $5.8 billion acquisition of the publicly traded Education Realty Trust. He was also the sole analyst for complex transactions, like a $40 million sale of a mixed-use set of three properties that included 300,000+ square feet of student housing, retail and office space, a parking garage, and a hotel—all on ground leased from a university.
His most recent role before joining Hearthfire was as director of acquisitions for a self-storage development company specializing in adaptive reuse projects. Isaac was responsible for sourcing and underwriting all acquisitions, as well as completing all market analysis. He also fulfilled asset management responsibilities for a portfolio of self-storage facilities in lease-up and assisted the company with its goal of raising a $50 million equity fund for further development.
Isaac completed his Master’s in Real Estate degree at Georgetown University to establish a firm foundation of knowledge for all major real estate types. His capstone project was on private sector neighborhood revitalization strategies and how they can be systematically applied to any city in need of renewal.

He is currently invested in two real estate syndications and looks to build a portfolio of real estate properties so he can live a fruitful, exciting life with his family.
Jim has a comprehensive operational and service background in the financial services industry. He began his career out of college in 2010 with SEI Investments, where he administered operational back-office functions for private equity, hedge and alternative investment clients.

In 2017, Jim transitioned his career to wealth management for ultra-high-net-worth individuals and families. He’s currently employed with Legacy Advisors, where he manages the firm’s daily operations and client service functions for the $2 billion RIA and wealth-planning firm.

Relationships are currency in the construction business, and Will has established an abundance of connections over the years—as a project manager, self-storage site manager, and owner of a construction company. As Hearthfire’s Director of Construction, Will manages all aspects of projects, from planning through completion. A significant part of his role includes building and maintaining relationships with contractors and subcontractors.
Will was introduced to the self-storage industry by a family friend who owned multiple self-storage facilities. After pursuing several years of training to become an electrical engineer, Will accepted a position as an on-site manager for a self-storage facility, overseeing day-to-day operations of the facility. Gradually he shifted to project management and spent several years managing construction projects and performing facility maintenance.
These experiences were the catalysts that drove Will to start his own construction company. For five years, Will’s company worked strictly with self-storage facilities. The company handled the construction of new steel buildings and general maintenance.
Will was introduced to Hearthfire when one of their self-storage facilities needed repairs. This came at a time when Sergio and Corinn were searching for someone to oversee Hearthfire’s new expansions, capital improvements, and facility maintenance.
Will is a huge NFL fan (go Colts!). One of his bucket list items is attending a game at every NFL stadium throughout the country.
When he’s not watching football, Will loves hunting and gaming. He’s also a technology connoisseur and has a side gig building computers.
