Eating healthy in the Bay Area shouldn’t be your second job.

The Bay Area runs on long workdays, and the drive down the peninsula or over the bridge takes what is left of the evening. Staying sharp here takes energy, focus and good health, and that starts with what you eat. Yet clean food is hard to find. Most of what is sold is full of additives, hidden sugar and industrial seed oils, behind labels that say otherwise. A personal chef in the Bay Area who cooks clean, organic food in your kitchen is the simplest way around it.

Your day starts early and ends late, and the commute takes the rest. Meal planning, shopping, cooking and cleaning are the first things to go, and your fridge stays full of good intentions instead of food.

You want fresh, healthy food that fits your diet. You just don’t want your evenings organized around making it.

Full time or part time Bay Area private chef services

We make healthy eating in the Bay Area effortless with our BioChef services.

Biospan offers three private chef Bay Area services. A part-time BioChef is your meal prep chef at home one to three days a week, a full time private chef runs your kitchen five to six days a week, and personalized nutrition support can be added to either. Start with how often you want a chef and how deeply nutrition should be integrated. We can help you decide.

  • Bay Area meal prep chef, for your dietary requirements

    Your BioChef visits one to three times a week and keeps your fridge stocked with labeled meals.

    Most meal prep companies in the Bay Area deliver the same containers every week. Your Bay Area meal prep service starts with your dietary requirements instead: your BioChef cooks in your kitchen, serves something hot on the day and leaves up to 16 portioned meals for the days ahead, and your weekly menu rotates so you never eat the same five meals.

  • Full time private chef at home in the Bay Area

    A chef in your kitchen five to six days a week.

    For fresh daily meals, dinner parties and food for your family and guests, a full time private chef at home cooks breakfast, lunch and dinner, supports the wider household and can travel with you.

  • Personal chef and nutritionist support

    We support your existing program or build you a personalized nutrition plan.

    Bring a plan from your nutritionist, doctor or coach and your BioChef cooks to it. Or ask Biospan for blood work and a personalized nutrition program built around your goals, with Cellular Performance, our partner.

These are starting points, not fixed packages. Your final package is shaped around your needs.Prefer to talk? +1 929 249 5444 · info@biospan.ioFind My BioChef

Bay Area personal chef and nutritionist support

Every menu starts with your nutrition.

BioCheffing was built so you never have to second-guess what you are eating again. Your menus are designed around your goals and requirements before any cooking begins. You do not need a formal program: start with clean, personalized food, bring an existing plan, or ask our nutrition team for deeper support.

Explore Personalised Nutrition

Fat loss, lean muscle, energy, sleep and longevity can all shape your menu. Your BioChef cooks for the goal, with macros and calories portioned when you want them, and the food you enjoy done clean.

Allergies, intolerances, exclusions and household needs are captured before menus are planned. If you follow a specific diet, keto, paleo, low-FODMAP, autoimmune or low-histamine, or a recovery protocol alongside your medical team, your BioChef cooks it as written.

A program is optional. We can work with the program and trainer you already have, or build one around your goals with Cellular Performance, our partner, and refine it as your results come in.

Organic private chef groceries in the Bay Area

Your chef shops for clean organic groceries.

Your menu is only as good as the ingredients that go into it. An organic private chef service starts with the shopping: in the Bay Area your BioChef sources organic produce, pasture-raised, 100% grass-fed meat and wild-caught fish to Biospan’s organic food standards, from suppliers such as Berkeley Bowl, Good Eggs and Marin Sun Farms, alongside California farmers’ markets and regenerative farms. Groceries are at cost. We make nothing on them.

Read our ingredient standards

Organic, seasonal and local wherever it is available. Your private chef shops for every ingredient personally, from your preferred Bay Area suppliers or our vetted suppliers (BETA).

Your chef cooks with whole foods and single-food natural ingredients: pasture-raised meat, wild-caught fish, organic vegetables. Your menus follow Biospan’s food standards, whichever private chef service you choose.

Your meals are cooked without industrial seed oils and refined sugar, with nothing ultra-processed. We cook with healthy fats to your program, or default to olive oil, ghee and tallow.

How an in-home cooking service in the Bay Area works

Your BioChef cooks your food in your own kitchen.

Hire a chef to cook at home and this is what your week looks like. Your BioChef is your personal cook and chef for hire in the Bay Area. Your BioChef plans your menus, shops for your groceries, cooks in your kitchen and leaves it clean, with in-home meal prep for the days ahead.

Your tastes, dietary requirements, schedule and required meals are turned into a practical menu for your household. Your chef reviews the plan and sources the organic groceries before cooking begins.

Depending on your service, your BioChef can prepare meals for later in glass containers, cook and serve something hot, make food for different household members or handle a full day of meals.

Prepared food is portioned, labelled and dated in your fridge. Your kitchen is left clean, and your next menu adapts to your feedback, travel, guests or changing goals.

What changes when the food is handled properly.

  • Steven Bartlett

    There’s a high chance of skipping meals or not eating things that are good for my nutrition if it’s not super quick and accessible.

    I have a chef that comes to my house once a week and he makes my meals for the next three days, and he comes back three days later and makes the next three. That’s been really important to me.

Private chef Bay Area questions, answered

What Bay Area households ask before they start

The practical details, answered before you inquire.

A private chef in the Bay Area with Biospan starts from $3,349 a month, all in before sales tax, with groceries billed separately at cost. That covers one chef visit a week in your own kitchen: a hot meal on the day and up to 16 portioned meals for the days ahead. Most clients start within 5 to 10 working days. BioCheffing is personalised nutrition with clean, organic ingredients, made by private chefs trained in nutrition.

Finding a Bay Area private chef through Biospan means the search is done for you. If you want to hire a personal chef to cook at home one day a week, or a full time private chef, tell us your requirements on Find My BioChef and we match you with a background-checked Biospan chef, in 5 to 10 working days on average. You trial your chef for one visit, you sign your contract directly with your chef, and your service starts with a complimentary nutrition call.

We replace your chef. Your personal chef match is built on your requirements and household fit, and if it is not right we find you another private chef in the Bay Area.

Yes. You trial your chef for one visit. For a full time private chef you can run unlimited chef trials, each paid at the chef’s agreed day rate.

Yes. Bring a plan from your nutritionist, doctor or coach and your BioChef cooks to it as written, with macros and calories portioned to your targets when you want them. We receive updates directly, so your personalized menus change as your plan changes.

Our private chefs cover the Bay Area, from San Mateo County and Santa Clara County to Alameda, Contra Costa, Marin, Napa and Sonoma, and we consider nearby areas on request. We cover San Francisco itself as well. Tell us your ZIP code on Find My BioChef and we confirm the search area before you commit.

Yes, and it is included rather than an extra. A chef visit is a full cooking session: your BioChef can serve something hot on the day and prepare portioned, labeled meals in glass containers for the days ahead. On one visit a week that is up to 16 servings on Clean Food, or up to 12 on the program packages, so meal prep is part of your package rather than something you add on.

Yes, with one week’s notice. When you travel, we can also match you with a BioChef at your destination who already knows your menus and requirements.

No. Your organic groceries are billed separately, groceries at cost, on your own card. Your private chef shops organic, pasture-raised and wild-caught, and we make nothing on your groceries.
