We feel incredibly lucky to have found Nana's Day Care. From day one, it's been clear that this is not just a daycare, but a truly loving, family-run home where children are deeply cared for and known as individuals. Nana and Athos have created a warm, nurturing, home-like environment that strikes the perfect balance between structure and play. The days are filled with activities that support curiosity, confidence, and development, while still feeling cozy and personal rather than institutional. What really sets Nana's apart is the level of communication and partnership. Nana is thoughtful, responsive, and genuinely collaborative with parents. She took the time to understand our child's needs, coordinated seamlessly around appointments, and always kept us informed. We felt listened to, supported, and fully trusted her with our son's care. It's obvious how much love and intention goes into everything they do. Our child was happy, well cared for, and truly known -- which is all any parent can ask for. Nana's Day Care feels like an extension of our family, and we would recommend it wholeheartedly to anyone looking for a nurturing, high-quality, in-home daycare in Marin. read more

Nana's Daycare is a warm, nurturing home daycare. Our daughter attended from 8 months to almost two years old, and it truly became her second home. Nana and Athos are caring, attentive, and very knowledgeable about early childhood development. They provided wonderful support around developmental milestones and transitions, always offering thoughtful guidance tailored to our child. Nana made the transition into daycare especially easy by sharing prompt updates and photos, which gave us real peace of mind. Our daughter grew into a confident, emotionally aware toddler and transitioned smoothly into a larger daycare afterward. Nana runs a well-organized, thoughtful program, and we highly recommend Nana's Daycare to any family looking for a trustworthy and loving environment. read more

Rosana and Athos provide such a loving and nurturing environment. Our son started at 4 months and thrived under their care with a small group of babies and toddlers. We always knew he was safe and well taken care of. read more

We were looking for a sitter for our kids for the day and found Nana's Day Care. This was our first time leaving the kids with a baby sitter and what a wonderful experience it was working with Rosana! She was absolutely perfect and took really great care of the kids! The moment we dropped off the kids, they felt extremely comfortable and enjoyed their day with her! Her place is wonderful as well, clean and very inviting for kids! She is super responsive and is very easy to communicate with. If you are lucky enough to use Nana's Day Care, you will not be disappointed! The kids can't wait to go back to her! Thank you Nana for such great care and service!!! I HIGHLY recommend her and her business!!! read more

This review is long overdue! My 2-year old has been attending Nana's since she was 5 months old. As a first-time mom, entrusting anyone to watch my baby was a little nerve wracking, to say the least. However, Nana absolutely eased my fears with her level of care, competence and communication. My daughter loves going to Nana's and has thrived in their care. Her vocabulary and interpersonal skills have really excelled, and she's made great friends at Nana's! Nana also does fun activities and crafts that are wonderful keepsakes. She and Athos are very nurturing and caring and bring out the best in my girl. As we transition to pre-school, we will definitely miss the support and care that Nana and Athos have provided us and my daughter for the past few years! read more

Our son started at Nana's when he was 4 months old and was there until he was a year old and we moved out of the area. Nana and Athos were amazing and loved our son like he was their own. As first time parents Nana made us feel incredibly comfortable and supported us with each phase, including transition to solids and moving to 2 naps. The space is cheerful with lots of toys while also allowing for safe exploration, which we really appreciated as our son became more mobile. Nana is very communicative and would often send pictures of our son during the day, always with a big smile on his face! We already miss Nana's so much but are immensely grateful for the time our son spent there. read more

We did a drop in for Nana's Day Care while we were on vacation, when we had a few hours of work. Our 4.5 year old boy and girl twins loved it! Nana and Athos gave off very warm and welcoming vibes. Their house is well situated with playground equipment (aimed for younger toddlers) right in the enclosed front yard, and there's a lovely playground right next door. Most of Nana's kids were younger (2ish), but they were so accommodating to our older kids - they did crafts, prepared activities for them, and Athos walked them to the playground while the younger ones napped. Highly recommended! read more

Our 2 year old son has been thriving at Nana's Daycare since he was 9 months old. We are so happy and thankful that we found Nana and Athos! He is our first born, and we were so anxious to have him start daycare as we both went back to work, but Nana and Athos quickly eased those fears. They pour so much love and care in to what they do - and our son was so happy to go to "school" each and every day! He has made lifelong friends, and has truly grown so much in terms of social and emotional growth while in their care. We couldn't recommend Nana's Daycare enough! read more

We could not have a higher recommendation for Nana and Athos! Our 2 year old son spent the past year under their care and he absolutely thrived. They created such a warm and caring environment, fostering his curiosity and growth. It was amazing to watch his development excel during his time at Nana's Daycare. We loved the smaller group allowing more 1:1 attention and it also encouraged great bonds with the other kids. It was so reassuring to know we were dropping our baby off in such good hands every day! As we make the transition to preschool we already miss them so much! read more

Are you looking for child care? One of the challenges that parents have faced during the shelter-in-place order is chaotic child care arrangements. I want to give a big shout-out to Nana's Day Care in Tam Valley for their brilliant program. They're kept us informed throughout the lockdown and will reopen next week, on 1 June. Our 2-year-old son started at Nana's when he was 6-months-old and we've been delighted with the support and care he's received. As parents, we've always received clear, informative communications and their program is professionally-run. Most importantly, our son is very happy at Nana's. We 100% recommend Nana's Day Care to anyone looking for child care! read more

We cannot recommend Nana's Day Care enough! Our 2 year old son has thrived in Nana and Athos' care over the past year. They are both incredibly caring, professional and create a safe and fun environment for the children. Nana is incredibly communicative with the parents and her schedule is flexible for working parents. We also loved that Nana provides healthy meals and snacks for the kids. Our son runs to their door every morning and has made so many friends! It's been so much fun to watch him develop and learn so many new things with Nana. We're going to miss Nana's so much as our son transitions to pre-school. read more

We love Nana's Day Care and we can't recommend it enough. Rosanna and Athos have a warm and loving energy and after just a few days our baby was waving goodbye to us at drop off. They very respectfully followed our baby's schedule and way of doing things which we really appreciate. Their home is now a warming familiar place for our baby. read more

Our experience with Nana was wonderful, we knew our daughter was well cared for each day. From the beginning it was clear she knew and loved kids, she was able to pick up on our daughters queues quickly to help her feel comfortable in the transition and get the support she needed. You can tell she takes great care of the children's environment and I never worried as there was clear and frequent communication. Would highly recommend for any family! read more

I could not say enough wonderful things about Nana and Athos! They are the most caring people and I could not imagine trusting anyone more with our infant daughter. As first time parents, their proactive communication about her day gave us so much peace of mind. And, seeing the smile on our daughter's face when she was there made it clear that she loved spending her day there - a priceless gift for a working mom! read more

My son has been at Nana's daycare since he was 5 months old. He loves it there and gets so excited to go each day. Rosana and Athos are so caring and conscientious. I honestly trust them more than anyone else. You can tell they truly adore these kids and are always looking out for what's best for them. Their daycare rooms are super clean and organized and are full of toys and activities. Nana is great at communicating with parents about their child (especially in the early infant stages when parents are neurotic about every burp and poop!) We love them so so much. read more

Our daughter Alix went to Nana's day care for two years and she absolutely loved it! We are a French family coming from Paris, and Alix never heard any english before. She was like fish to water at Nana's! Every day she came back talking about Nana and Athos. A real connection happened with Nana and Athos with our whole family. We trust them as much as possible (with our daughter actually!) and never regretted it. I strongly recommend Nana's day care for your children. read more

Nana and Athos are wonderful people, and run a wonderful day care. Our daughter went there for a year, before we enrolled her in pre school. Their home is clean and they treated our daughter as if she was their own. I cannot say enough great things about them. read more

5 stars! affordable, flexible, convenient and a full staff of kind and knowledgeable care givers! Nana's goes above and beyond to make everyone feel like family. I couldn't ask for anything more in a daycare. read more

Our daughter went to Nana's day care for 2.5 years and it was fantastic experience. Our daughter loved going to Nana's, as Nana and Athos, create an amazing environment for children to grow. As parents, we always felt so comfortable leaving our daughter with them, they are warm and kind, but also highly organized and clean. We are truly appreciative of the loving care they gave our daughter, and recommend them to anyone looking for daycare. read more

My brothers daughter went to Nana's. We were very excited to be able to send our son there as well while we were living in Marin. He loved it - from when he was just 6 months old! We cant imagine how there could ever be another daycare as good. Rosana and Athos are amazing. They really should get 6 stars. read more

Our daughter was in the care of Nana and Athos from the time she was 4 months old until she was 2 1/2. The care she got with the Oliveras was wonderful. The rooms the kids played in and the outdoor areas were always clean, organized and cheerful. All of the equipment used and toys offered were well cared for and clean. For the first year we got a daily report of her sleeping, eating and bathroom habits, which was very comforting for a working parent. When she was able to eat solid food, our daughter also received well rounded, healthy meals. Everything about Nana's Day Care was top notch. We were so pleased to have had the opportunity to share our child's first 2 years and growth with Nana & Athos. I would highly recommend their program! read more

Nana's Daycare is amazing! All of our three boys loved going to Nana and Athos. They have a great program, a great indoor and outdoor space, amazing food, super clean and most important - so much love for the kids! Daycare does not get any better than this!! read more

My second daughter just graduated from Nana's Day Care after two wonderful years in the loving care of Nana and Athos! Having now sent both of my children to Nana's I would of course highly recommend this Day Care to anyone considering day care for their child. I don't think my daughter ever cried once going and I was totally comfortable knowing she was in their care. Also never having to pack lunch was a real plus! Nana and Athos provided so much fun and love to our family and we will miss seeing them on a daily basis! read more

Our family had a great experience with Nana's. Their family works as a team with a lot of kindness and fun. They are also our neighbors and we always enjoy walking by and seeing the day care as a happy place in our neighborhood. Parents, you will get a very clear contract about prices, vacations, and rules around sickness. Nana's errs on the side of caution when it comes to illness and they are very prompt about reporting anything contagious that is going around. I never once felt that they weren't keeping up their end of the bargain and my kids were always happy and healthy there. It's a great environment and we're so grateful for Nana and her whole family. read more

Nana's Day Care has been the most wonderful place for our son to learn to socialize, while being extremely well taken care of, in a nice, clean and safe environment, with tons of toys, structured activities, and a fantastic playground. Nana and Athos are truly amazing and have been like second parents for our son. He has loved going there, and my husband and I have always been so impressed to see how calm, well-behaved, joyful and happy all kids there were, whenever we dropped off our son or picked him up. That, to us, says a lot about how Nana and Athos are taking care of the kids. They are the nicest people, and we immediately felt comfortable leaving our son with them. Nana and Athos are also highly responsible to ensure that the group of kids stays healthy. Our son has developed so much since his first day at Nana's Day Care (the day he started walking on his own!), and we will remain eternally grateful to Nana and Athos for taking such great care of him. Thank you Nana and Athos! read more

My son went to Nana's for 3 years (since he was 3 months old) and I can't rave enough about the positive experience we had. Nana and Athos are wonderful people and I felt comfortable knowing my son was happy and healthy in their care. They were great communicating about food, nap and bathroom schedules while he was a baby. And helped with potty training and teaching as he got older. My son still talks about going to Nana's and we continue to keep in touch with the family. read more

When you can't care for your little ones yourself, you can only hope to find a second set of loving parents like Nana and Athos. Both my daughters went to Nana's for about 2 years each and I cannot speak highly enough of the care and attention they received. Their space is organized and clean with a beautiful play area outside, but most importantly I always knew they were SAFE. Nana makes that a top priority and for a busy working parent that peace of mind is golden. It's an absolute bonus that they are the kindest, most loving people who became part of our lives and my daughters still talk about "Nana's" to this day! read more

Nana and Athos are the best!! Kind, caring, sincere. Our little boy went to Nana's for a year and a half and we always felt that he was in good hands. We recommend them highly!! read more

Our 10 month old son has been going to Nana's since he was 3 months old and we love it! Nana and Athos are so loving and caring and you can tell they really enjoy taking care of all the little ones and watching them grow. Every morning at drop off our son gets so happy when he sees that we are at "school" and every evening we pick up a happy boy and are given a run down of how his day was. We couldn't ask for better care and would recommend them to anyone looking for daycare. read more

This family child care is an excellent infant toddler program. Nana and Athos are very nurturing and thoughtful, paying detailed attention to the children. The environment is warm, friendly, organized and fun. Our daughter attended the program from 1 year to a little over 3 years of age, and we always felt she was in such good, caring hands. read more

We sent our daughter to Nana's starting when she was 4 months. Nana and Athos provide the most loving and nurturing care that a parent could ask for. I never worried about our daughter or her care there, such a relief to feel so comfortable with your child's caretaker. Would definitely recommend! read more

We had a wonderful experience with Nana's Daycare; Nana and Athos are like family to us. The daycare is conveniently located - just a short walk from Tam Valley School and across the street from Kay Park. The environment is extremely loving, clean and well organized. It's great for infants through preschool age. The children enjoy music, indoor/outdoor play, arts/crafts, and plenty of fun and age-appropriate toys. We recommend Nana's Daycare very highly! read more

We sent our son to Nana's when he was 4 months old until he was 2.5 and his sister also joined Nana's when she was 4 months old. Nana and Athos are very loving and caring and we were very happy with the care they provided for our kids, we trust them wholeheartedly. Nana provided excellent communication about everything - from relaying how their day went to helpful tips on napping/sleeping/eating. The hours from 8am-5pm can make it a little tricky for full time working parents, but we made it work because there really wasn't any other daycare that I came across that made me feel as comfortable as Nana's. read more
