I chose Klein Hornig because its mission and people-first culture align with my approach to HR – clear communication, consistent support, and follow-through that enables employees and leaders to deliver results. I’m excited by the firm’s impact on affordable housing and community development and I would love to support that impact by creating a strong, supportive employee experience.

I’m an HR professional known for a service-oriented approach rooted in kindness, listening, and practical problem-solving. I care deeply about giving back through community service and I’m happiest in a quiet atmosphere—whether that’s reading, traveling, or spending time at the beach. I’m also a proud mom of two teens and a dog mom to a 3-pound Yorkie.
