Although Susan Adams never sought fame, her influence endures in the lives she influenced, particularly in the case of her daughter Mackenzie. In her early years, Susan worked in places where power was felt, most notably as Robert McNamara’s personal secretary, a position that demanded extraordinary intelligence, accuracy, and a level of composure that was nearly unshakeable.
She left that world behind and married John Phillips, a man who, tragically, destroyed his family in private while also defining a generation musically. Like many relationships tied to addiction and fame, theirs deteriorated over time. Quiet but not helpless, Susan went back to her job as a mother in a chaotic household.

She was quiet. She lacked glitz. But by all accounts, she was trustworthy in a life that wasn’t always that way. Even though the walls trembled, Susan chose stability over the indulgence and fame that came with John’s rock star path.
Mackenzie Phillips would eventually have to face the unpleasant realities of her childhood in public, including her father’s long-term abuse. Her thoughts on her mother, however, were colored differently—not with resentment, but with unadulterated grief intertwined with admiration. She wrote about witnessing Susan’s decline into dementia in her 2017 book Hopeful Healing with a kind of painful clarity that few people dare to express.
Losing a parent is one thing. It’s another to see their light gradually fading every day. Susan eventually required help remembering the most basic things after being able to command high-level attention in the Pentagon. Mackenzie was deeply saddened and angry at that decline, which was remarkably similar to watching a light flicker before leaving.
Susan’s routines became more straightforward as she lived in an assisted-living facility in her last years. Knowing that the woman in front of her couldn’t react the way she used to, Mackenzie wrote about going to see her mother and resisting the impulse to say, “I need my mommy.” That instance, conveyed without self-pity, demonstrated how dementia alters emotional geography in addition to erasing memory.
And there was guilt. The kind that waits to be outlived rather than pleading for forgiveness.
Nevertheless, there were brief bursts of humor when Susan’s witty tongue cut through the morphine’s haze. In one such scene, she muttered something so direct, so specifically “Susan,” that it made Mackenzie laugh through her grief as her beloved (or perhaps barely tolerated) cat Bubbles climbed onto her hospital bed. Unscripted, darkly humorous, and surprisingly consoling, it was a profoundly human moment.
Mackenzie characterized her mother’s passing as “sweet mourning.” It was a surprising phrase. It eased grief and created space for thankfulness.
The fact that Susan was sober for eighteen years prior to her death is a detail that is easily forgotten but incredibly impactful. Susan had struggled with alcoholism for decades, and addiction can spread like wildfire in families. It matters that she passed away sober. Her story is reframed as one of quiet triumph as well as decline.
Mackenzie talks about putting on her mother’s sapphire ring or donning her black blazer with an air of intimacy. These represent a bond that was weakened but not broken; they are not memory props. Yes, it is inherited. but earned as well.
Now working as a rehab counselor, Mackenzie guides people through the difficult times her family barely made it through. That decision seems especially creative. She honors her mother not only with words but also with action by taking on the task of recovery. by being there.
Susan Adams is remarkable for her ability to convey meaning with minimal words. She wasn’t looking for a legacy. However, she left one through her daughter’s meticulous writing and her own unwavering recuperation.
Susan’s restraint is noteworthy in a time when everything private becomes public knowledge. Her influence was lived, not announced. Perhaps the most enduring influence is the kind that subtly leaves an impression but doesn’t actively seek recognition.
