Our Founder
Shamrock Highlands Thoroughbreds started first as a concept of race horse ownership combining all the strengths of established partnerships with a broader vision of ownership going beyond a single stable or region.
Founding partner Jeff Callan established contacts and purchased ownership shares in disparate regions with highly qualified trainers, but working from his experiences both as a businessman
starting his consulting business in 2002 and in the racing business starting 1984 as a standardbred trainer, owner, and driver to his transition to thoroughbreds spending 15 years of
pedigree research to a current owner,, he realized he could link his growing network of contacts in a way that could not only benefit him as an owner and investor, but other prospective owners and enthusiasts seeking the experience of thoroughbred racing.

The Process
How it Works
Discovery
We will look at and review hundreds of horses, eventually yielding 25-30 that we see potential in. We proceed in ranking these, consider veterinary reports, physical review and acquisition costs per the value of the horse. These additional factors will disqualify many of them before we find 10-15 that fit the criteria.
Strategy
Finally, when we execute the acquisition strategy (via private purchase, public sale, or through claims) we close only on assets that have the markers of improving value. After our purchase, we allocate partnership shares on a first-come first-served basis, making offerings that first consider your particular strategy.
why we do it
Our Mission
As people with a passion for thoroughbred racing, our vision was to find a way to dive into the sport with a group of like-minded people who share our passion, but might not have the time to manage a twenty-horse stable, or the raw capital to lease and staff that stable in its formative years.
About Us
What Makes Us Different?
On Investment Availability
The others claim horses and then offer shares or ownership percentages. Some may offer interests of horses in training. These partnerships often use a simple “take it or leave it” approach. The prospective interest-owner is left to pick from horses that are currently available, and is essentially on their own when it comes to developing and implementing a broader portfolio-ownership strategy.
Shamrock Highlands Thoroughbreds will work with your desired resource investment and personal goals to build a strategy, and go to work to put the pieces in place–by seeking out acquisitions available privately, in upcoming sales, our available shares of current partnerships, or claiming opportunities for the partnership.
On Geographic and Scaling Investment Opportunities
The others typically tie a shareholder to a region, a trainer, or a stable.
Shamrock Highlands Thoroughbreds’ structure covers all the major US racing regions. We’ll help you to develop ownership shares in the right place and situation for what you want to accomplish. Our national footprint means that our partnership offers you a broader ownership availability, as well as the opportunity to send the partnership’s horses where they’ll develop best and have the greatest potential, ensuring our partners have the best chance for success and profit.
On Costs and Ownership Portions
The others have roll-up costs and fees, and offer ‘micro shares’ of properties with ownership on paper, but negligible involvement, influence or communication in the stake.
Shamrock Highlands Thoroughbred’s costs are broken down to be straightforward and transparent. Costs are structured to maintain the basic costs of operation, but partners only make money when you do. Our minimum available stake is 10% ownership, which gives you skin in the game, and a real sense of ownership.
On Acquisitions
The others allow you to buy shares in a horse or horses that are already owned by the stable or partner.
Shamrock Highlands Thoroughbreds also offer horses with open available shares for sale, but when making additional purchases, we search and selects horses to match the strategies and goals of our partners. After our homework is done and we’ve ensured it is in line with our strict criteria, we make the purchase by negotiating a favorable price (with exception to claims. [See our Costs page for more details.]) If our partners have their needs fully met, we will always be on the lookout for opportunities. In some cases, the managing partners will make full investment purchases up-front and offer ownership shares at some point in the future.
Like any successful business, the strategic basics are all present: develop a solid plan, commit to due diligence by doing the research and paying close attention to every detail, and execute.
What makes Shamrock Highlands different is that our managing partners will work with you to develop an investment strategy. We will listen to your goals and desired level of investment and have a discussion to develop an acquisition plan that fits your objectives.
While there are many options out there, each with their benefits and spot in the industry, we strived to offer something different and unique in the thoroughbred marketplace. We tailor what we do to what you want to achieve.
