Clients, awards, & recognition.
Kathi's reputation has been built one engagement at a time. From the country's most prestigious law firms to Pasadena's most discerning institutions to family-held businesses navigating once-in-a-decade decisions.
We could not more highly recommend Kathi. She walked us through a process we weren't familiar with, made us feel comfortable, and reached out long after the transaction was done. There's a reason she's number one — she's one in a million.
What clients keep saying.
Six lines repeat across nearly every testimonial: she answers her phone, she's prepared, she's relentless, she's warm, she stays in touch after closing, and she gets it done.
I admire Kathi for her resourcefulness and creativity in solving any challenge that arises. She is masterful at connecting the dots and marshaling people and assets toward a common aim. She is also fun, genuine, and brings an amazing smile, positive attitude and "can do" mindset into everything she does.
Kathi is extraordinarily hard-working, honest and dependable — a broker that is not easy to find. She is great at what she does and goes above and beyond for her clients.
Kathi Constanzo oversaw the process to successful completion of finding a new office space in Pasadena to fit the multifaceted needs of my company. Her utmost professionalism and expertise proved invaluable throughout the entire process. She is determined, forthright, and incredibly thorough. I couldn't speak more highly of her, and recommend Kathi to anyone seeking commercial real estate.
Kathi's meticulous attention to detail, infectious personality and intense drive to help others are just a few traits that differentiate her from others. She will work tirelessly to meet the needs of her clients and do it with the highest levels of enthusiasm. She is someone you will want to work with and know for a lifetime.
Kathi is great to work with. She is energetic, enthusiastic, and a great provider of solutions whenever an issue came up. She made the process easy and presented our property well. I would trust her again and recommend her highly.
Thank you for "spilling the tea" with us — sharing your wisdom, your real-life experiences, your lessons learned, and your success stories. You didn't just give us information — you gave us inspiration. You showed us what leadership looks like in action.
