"I consider myself fortunate to have Frederica Tassis as my agent. I had no idea how much a real estate agent had to work for a client. She represented me tirelessly. I had no worries. I also appreciate that she replied to all my questions, and there were many some of them rather elementary, promptly, and expertly. Thank you, Frederica!"

She is always willing to make time for open houses, explain the purchasing process, and make sure you feel comfortable during what can be a stressful time. She knew what we wanted and we happily ended up in the perfect house! She's friendly, knowledgeable, professional, and will get the job done. Highly recommended!"
