Dr Phillips is a nice area. Dr Phillips High school is also a performing arts school-big on acting, chorus, etc but also sports like football.
There are a couple of high schools (depending on where in DP you are) Olympia is the other.
The areas closest to Sand Lake Rd are going to have more traffic as Sand Lake is busy with lots of shopping and restaurants. If you cross over Sand Lake Rd on Turkey Lake Rd down to Wallace. Turn left on Wallace and the areas here are older but nice. You will find a combination of apts on the left and houses on the right.
Firther down as you get closer to Dr Phillps Blvd and also the area of Conroy Rd and Apopka Vineland, houses are newer and a pricier.
(If you stay on Conroy past Apopka Vineland you will enter Windermere which is way up there on some of the houses. It's really a mixture as you will see little run down houses right next door to a fairly new mansion. You will also see that some roads will be paved and some will be still dirt roads.
Also at the corner of Apopka Vineland and Conroy there is a shopping center and a plaza that has a pediatricians office that is very good if you need info. on that.
Your best bet is to call a realtor in an area that you think you want to live in.
There are areas in central florida that are nicer than others and you will have to feel the realtor out as they will say that they aren't allowed to really talk about crime and what certain areas are like- but I will be more than happy to tell you! LOL
I have lived in the area for more than 20 years and have watched it grow and change, slow down, more change and then grow again.
Generally, you won't have any problems in DP area though. IMO
*I just saw that you wanted to move down when your dh retires. Although there are retired folks that live in Dr Phillips, you might also want to consider areas that are maybe a little quieter traffic wise as well. Talk to a realtor about this as well. Maybe an active adult over 55 area would be more fun. There are a few of these out in Clermont on Hwy 27 that my parents are looking at over near Kings Ridge. Nice, reasonably priced and close to shopping.
The people that live in there take their golf carts to Publix and do their grocery shopping, its so close.
