Taneshia Crenshaw
Realtor ®
The Harrington Team
A proud Michigander, born and raised in Kalamazoo, I bring a passion for people and a deep love for my community. With over 20 years of customer service experience, I’ve developed a strong skill set in authentic connection and communication.
My background includes leadership roles in management and business ownership, as well as nearly a decade working at Kalamazoo’s largest law firm—specializing in litigation, corporate, patent, and real estate law. During that time, I earned multiple certifications and learned the importance of precision in legal contracts—an asset I bring into every real estate transaction.
I began my real estate journey in 2020 with Century 21 Affiliated. I proudly transitioned to full-time real estate with Keller Williams Realty – Blue Horizon Group. I’ve successfully closed millions in real estate transactions. What fuels me most is helping clients navigate one of the most important decisions of their lives.
Whether you’re buying, selling, or investing, my priority is to deliver an outstanding client experience inclusive to ALL people.
Outside of real estate, I enjoy spending quality time with my family, yoga, reading, trying exotic cuisine, and traveling the world to experience new cultures.
I’m honored to serve Greater Kalamazoo and the surrounding areas. I look forward to helping you with your next move!
