Exceeding Expectations, Every Time

She sold my investment property and I am building an ultra luxury estate in Beverly Hills - Catherine is my go to for real estate advice, luxury marketing and advertising PR. From staging to touring construction sites she really does it all.

I'm writing this glowing review in my new house, looking out at a gorgeous view. And I can say this thanks to Catherine Ammann! Because of her expertise, tenacity, patience and experience, we found the home of our dreams.
— Mark C.

— Vinny Z.
Catherine is great! She is very responsive, thorough and is with you throughout the entire process to make sure you feel comfortable every step of the way. Definitely recommend.
— Mala K.
Catherine is an excellent real estate agent. She expertly guided my wife and I during the process of identifying our home. We were buying our first home in one of the most competitive housing markets (summer 2021), and Catherine was the best advocate we could have hoped for. She was on the ball with quick turn times and strategic decisions. She went above and beyond to get us a great deal and guide us through a stressful escrow. Any homebuyer (or seller!) would be so lucky to have Catherine in their court.
— Elizabeth A.
Gigi was so different in her approach. She was patient, professional, highly knowledgeable, communicative, and authentic. We sold our first home with her and made the best decision to choose her as our realtor. She was a relentless advocate yet made the transaction a smooth process. Gigi is incredibly trustworthy and we highly recommend her.
— Mr. & Mrs. Lee
