Wynonna and Naomi Judd have been at the top of the country charts but they've also been down a long and bumpy road worthy of a somber country song. And it tested their relationship.

But with the help of a counselor they've been seeing since last year, the five-time Grammy Award-winning mother-daughter duo ? who star in the new documentary series The Judds, debuting on OWN April 15 ? are stronger than ever.

"[Our therapist] said, 'It's a true miracle how far you've come, and that you all are doing as well as you have [been doing],' " Wynonna, 46, told PEOPLE Monday during a conference call promoting the show, which explores their life on tour again and performing together for the first time in ten years. "He said it's one of the top moments in his profession to see us come as far as we have."

In 2003, Wynonna was charged with DUI. In 2006, her sister Ashley went to rehab for emotional issues. In 2007, Wynonna's estranged husband D.R. Roach was charged with three counts of aggravated sexual battery against a minor. And last July, Wynonna and Naomi were involved in a head-on collision.

Naomi, 65, echoed her daughter, saying of their progress, "[Our counselor] said in 25 years of being a Ph.D. psychologist, he's never seen people who love each other as deeply and whose intentions are [so] pure."

The Judd matriarch, who calls the show "real" and unscripted, tells her daughter during the call, "We can agree to disagree ... I support who you are because I love you and I know your intentions are good."

As for Wynonna, "I have been in a healing recovery process since 2003," she said. "And of the most important and sacred things on my list of priorities was to heal my relationship with my mother."
