It's a bit farther down the road (coit and spring creek) but Pebblecreek Montessori is FANTASTIC. My daughter has been there since last August and it's amazing how much she's learned. A lot of 2 y/o know their shapes, colors, and can count but my daughter also understands abstract concepts (things my son is just now learning in Kindergarten!) like heavy/light, bigger than, less than.. etc. I did a lot of research before I enrolled her here and found them to be one of the most traditional montessori schools around. They also have a scholarship program too and as a single mom and college student you'd probably be eligible to qualify.
Good luck
