She is now a photographer based in L.A. She doesn't look much different now than when she was acting back in the 70s.

Here she is, then and now:

I think these days she looks a lot like Marcia Strassman (Welcome Back, Kotter).

She has aged very gracefully! She looks beautiful and I agree there is a definite resemblance to Marcia Strassman!

She also has a son who is a doctor, according to her Search For Tomorrow co-star, Maree Cheatham. Her SFT husband was Joel Higgins, who went on to play the dad on Silver Spoons. Anne was also Mark Hamill's first love - they broke up around the time Star Wars came out. Here's a picture and blurb from a July 1977 issue of People:

Then followed 89 guest parts on prime-time TV and a run in the soap General Hospital, where his "sister" on the series, actress Anne Wyndham, was his lady offstage.

Now she's in New York starring in another soap, Search for Tomorrow. "I've always been in love with her, but it's rocky," Mark confides. So in L.A. he recently decided, "Quick! I have to find somebody who really likes me before Star Wars opens." Like Mrs. Ladd, she's a dental hygienist. But Hamill's career and romantic pendulum may be veering back east toward the stage and Anne. "At big Hollywood parties," he says, "I watch what happens to my personality, and I don't like it." Then there's another problem about the Coast. He hasn't bought another car yet.

P.S. Mark Hamill ended up marrying the dental hygienist in 1978 - Marilou York. They are still married after nearly 34 years of marriage!!
