In-home, lifestyle-focused sessions for babies typically 5–21 days old. I come to you — no studio, no props — just your baby, your home, and the quiet magic of those first weeks. I work around feeding schedules and fussiness. No rushing, no stress.

The Approach

Photography that looks like your actual life.

No stiff poses. No forced smiles. No chaos — just you, your people, and 45 focused minutes at a beautiful location in Marin County or San Francisco. I work quietly, follow your lead, and document what's real. The sessions that produce your favorite photos are almost never the ones where everyone behaved perfectly. They're the ones where something genuine happened.

What Families Are Saying

Session photo for Morgan — Maternity + Newborn photography in Marin County
"I just want every moment to be captured by Cass because of her deep understanding of art and the human experience. She makes works of art with her photos. I love her way of looking at individual moments. It felt like Cass introduced me to a new version of myself during our maternity shoot. She has gained a client for life!"

"Cass is an amazing photographer. I could not believe how many gorgeous shots she got — I was in tears when I received the gallery! She is also such a caring, warm and kind photographer that put us at ease. The session felt really natural. We HIGHLY recommend Cass!"

Session photo for Courtney — Maternity photography in Marin County
"After looking at the portfolios of at least a dozen maternity photographers in the Bay Area, I knew Cass was 'the one' for us. She captures all aspects of the beauty of the moment — the people, the emotions, the environment — and her style makes them even more magic."

Session photo for Alexis — Newborn photography in Marin County
"We look through the pictures all the time, and I am so glad we will have these to reflect on and to share with our baby when she is older. We felt immediately comfortable with Cass in our home — she was so respectful and put us and our babe at ease. We felt like we were hanging with a friend who happened to be photographing our baby. She is truly a gem!"
Alexis / Newborn
Session photo for Anna — 7 Year Old Birthday Party photography in Marin County
"Joy, movement, silliness, community, and cheer. Cassy beautifully captured the essence of my 7-year-old's birthday party. It was so nice to be present, knowing that Cassy was documenting the day. She moved around the party like a ninja, taking photos of people in the moment. It was also great to see me in the photos, enjoying time with my kids! I'm so grateful to have these photos to remember the day."

About Cass

Photography has been my passion since 2007. I'm a mother of three and a longtime Marin resident, and I've been documenting the beautiful chaos of local families since 2018.

Whether we're shooting a newborn mini session in your home in San Anselmo, a family session at Old Mill Park in Mill Valley, or a maternity shoot at Baker Beach, my goal is always the same: finding the visual poetry in your everyday life.
