I've lived in HOU all my life. Not just near the Med Center, but Spring Branch/Memorial City area, Sugar Land, Pear Land, and even Cypress ~ which I love the most because of the demographics, no flooding, & trees/space. Mind you, I commuted to the Medical Center for school and even work. I'm familiar either by working or clinicals at The Methodist Hospital (med center/ Sugar Land / Willowbrook), Hermann Hospital (med center & Memorial), Texas Children's Hosp and Harris County Hosp (Ben Taub & LBJ).
HOUSTON is big and you're in the right place to get as much experience as you can. I wish I didn't have to relocate, but I could go back to the Med Center, I would!!!! I already miss the Southern hospitality, food, & people. Commute is a b*tch... I wouldn't even say that if I didn't live it every day I worked and on my days off. Remember, if you work in the Med Center, you have to take classes/inservices in your hosp; so, factor in another day of driving thru traffic, even if you work nights, which I did a lot. You can park & ride conveniently if you lived in Sugar Land. Otherwise, get a 1000-1800 shift, which I had once.
The Woodlands & Katy area is booming too...
Really, any of the hospitals in HOU is a "good place to work" as long as you find that specialty/unit you fall in love with.
