Find your space, check with city hall to make sure it's zoned for dental or doctor office, sign your lease after consulting with an attorney, get a no collateral construction and business loan from Schein/Patterson and they'll come by and design the office to your satisfaction for free. Then call an Asian/Mexican builder rather than the one they recommend since they always do it for so much cheaper. It is very possible to build a 2-chairs (but plumbed for 3 or 4) fully operational practice for under $100K. Go to city hall and sign up your business. Sign up with a couple dental insurance companies. Have your wife, sister, mother, or brother work front desk and assist for the first few months. Don't get expensive unnecessary toys like laser, Cerec machine, the Wand, air abrasion, digital xray, camera, complicated dental software, nitrous oxide, digital caries detector, consultants, etc. because they cut deep into your bottom line and further your debt. It would be nice for everyone to have a Nordtrom-type practice, but there aren't too many rich people so having a Walmart-type practice in keeping everything cheap, basic, and simple works just as good and bring in just as much money from the masses.
