Stephanie was super flexible with my purchasing schedule and was very understanding of timelines/ cutoff for the home search. She was very communicative and proactive with the search and identifying candidate homes during the search. We encountered some minor issues during the inspection on the candidate home and she was very helpful in helping me understand action items and scheduling as well as alternatives to put in the contract if insurance inspection didn't go as planned. Overall great realtor to work with!

Incredible to work with. The "Sherlock Holmes" of realtors.

working with Stephanie is an education. She is a master detective at asking the right questions, interpreting your answers to find the right property and having the ability to negotiate a great price. This was a concurrent condominium sale and purchase. Her knowledge of the area enabled her to find my little gem and she skillfully navigated us through the challenge of both properties closing simultaneously. Perfection!

Patient, knowledgable, helpful, friendly, honest, trustworthy goes out of her way to help.

Stephanie has helped me with multiple real estate transactions both selling and purchasing as well as getting loans. She has decades of experience at many levels and aspects of the real estate industry. To find a broker agent with such a breadth of knowledge from loan to purchase to sales and even more obscure real estate or loan topics is unusual today. Combining her years of experience with her wide knowledge, patient understanding and friendly personality makes her a rare person in the real estate space. She is honest, hard working and genuinely cares about helping people get the most they can get out of any transaction wether its a loan, purchase or sale. This is why I continue to rely on her expertise and understanding. Despite the changing real estate landscape and the advent of social media as well as large .com websites she keeps up with the latest laws and trends. If she isn't certain a
