My roots are both in the San Francisco Bay Area as well as Switzerland, and I have no interest in selling or renting anything to you, so I can be a neutral source of objective, analytical information to someone faced with your challenges. (I faced the reverse challenge when I was sent to Germany.)
Where in Switzerland are you coming from? Zurich stadt-zentrum? Pfaffikon-Sz? Lucerne? Winterthur? Most likely Basel, would be my guess... (My family roots are in Uri, Altdorf, and a good friend Cesar, owner of the Hotel Schiff, Pfaffikon SZ, will verify that I am real, should you check.)
The answer to your question of where to live and where to educate your kids...begins with what you are accustomed to lifestyle-wise, what you are comfortable with commute-wise, what you expect, and your level of income. Everything begins with these questions. Depending upon your situation, a list of pros and cons can be developed. Feel free to contact me directly via email and I can be helpful. email@example.com
The same offer goes to others who are considering Pleasanton. It is a **great** community.
P.S. I have lived in San Francisco and Silicon Valley as well as Europe, and here is no place like Pleasanton if you have children to raise.
