That is how her Coldwell Banker biography opens, and it is fair. She has been licensed since 1984, was the Austin Business Journal's #1 selling agent for four straight years, ran the #1 selling team in 2002, and has handled multi-million-dollar transactions on Lake Austin and in Westlake ever since. What she is known for around town is more particular: waterfront. Her direct line spells 789-LAKE. Her sold record runs from a 7,110-square-foot Rob Roy waterfront estate to a Tuscan-style house on 1.2 flat acres of Lake Austin, and the portfolio on this site is thirty years of the marketing pieces she mailed for them.

The Tosca Gruber group listened to all of my wants and needs and went above and beyond to make sure I was more than satisfied with the result. Coming from GA to TX mid-Covid in this market was a nightmare enough, but they made sure I found a reasonable price point for a side of town that will increase my home value once the surrounding commercial areas are fully developed. They showed me this whole experience doesn't have to be completely stressful. Courtland L.Bay City, MI (moved from GA) · Dec 2021[on Yelp](https://www.yelp.com/biz/tosca-gruber-coldwell-banker-realty-austin) Thank you so much for all of your help in our home purchase! We are so grateful for all of the hard work, process knowledge and most importantly the kindness you all exemplified in the process of our home transition. Not only did you help us sell our home, but truly find our dream home as well. We are endlessly grateful to have you all as our real estate team and couldn't be happier with the way everything worked out! Megan H.Leander, TX · Nov 2021[on Yelp](https://www.yelp.com/biz/tosca-gruber-coldwell-banker-realty-austin) Had a great experience working with the Tosca Gruber Team these last few weeks. They were professional, very knowledgeable about the city and the local businesses, and were an absolute pleasure to work with. They called every morning while I was searching for a place with MLS sheets ready to go, and found a great central location at an excellent price. The team was very quick and communicative when it came to questions about move in documents, and the whole process was easy and educational. Couldn't recommend this group more! Ben L.Memphis, TN · Dec 2021[on Yelp](https://www.yelp.com/biz/tosca-gruber-coldwell-banker-realty-austin) As a first time home buyer I don't believe the process could have gone any smoother. Tosca and the team were very helpful in walking me through all the steps and did everything on their side to make sure I got the house I wanted on the closing date I wanted.
