Hi I dont know anything about the hospital but Kearny Mesa is ok. It depends where in Kearny Mesa. There is a lot of traffic durring the rush hours on the side streets, a lot of stop lights. Tons of businesses, plenty of places to eat and tons of car dealerships. It gets really hot there too durring the summer. Its not a bad place if you are just going to and from work but its not the most beautiful place in San Diego either.
