Executive Team


SUSAN MAY McLEAN, Managing Principal

Susan thrives on the vitality and the challenges of the title industry. Although there is always something new, from the parameters of a deal to the regulations that guide them, for Susan, one thing has remained constant throughout her 20+ years in the business: the importance of maintaining the trust and confidence of her clients.

She earned her industry credentials as Chief Business Development Officer and a banker in the collections and non-performing loan departments at Citicorp and the Dime Savings Bank.

As Managing Principal, Susan believes in providing a level of customer service that extends beyond the actual transaction. “I like nothing better than “connecting” people. Throughout the course of the day, or at one of our well-regarded networking events, I will introduce like-minded business individuals, bring to my client’s attention an opportunity that could help grow their real estate portfolio or suggest a resource that might aid in financing. This is not an extra or for-profit service– this is just part of the Horizon business philosophy.”
