Insurance made simple, in the language you speak.
For more than two decades, families across California have trusted CISA to guide them through Medicare and beyond — with patient, personal help from licensed agents who speak your language and put your needs first.
A local agency that treats you like family.
Common Insurance Services Agency was built on a simple idea: everyone deserves to understand their coverage, in their own language, without pressure. Medicare and health insurance can feel confusing and overwhelming — especially when the plans keep changing every year. That’s where we come in.
Our licensed agents sit down with you, explain your options in plain terms, compare plans from many top carriers, and help you choose what truly fits your life and budget. We’re independent, so our only job is finding what’s right for you — and our help is always free.
Coverage for every stage of life
One trusted team, many options. We represent a wide range of plans and help you find the one that fits — then we’re here all year if anything changes.
Medicare
Medicare Advantage (Part C), Prescription Drug plans (Part D), and Medicare Supplement — explained clearly so you can choose with confidence.
Covered California
Health coverage and subsidies for individuals and families under 65. We’ll check what you qualify for and handle the paperwork.
Life Insurance
Life insurance with living benefits — protection for the people who matter most, plus value you can use while you’re living.
Retirement & Annuity
Annuities, IRAs, and 401(k) rollovers designed for income that lasts. Plan today for a comfortable, worry-free retirement.

Common questions
How much does it cost to work with CISA?
Nothing. Our guidance is completely free to you. We’re paid by the insurance carriers when you enroll, so you get expert help at no cost and with no obligation.
Do you speak my language?
Very likely, yes. Our agents speak Vietnamese, Mandarin, Cantonese, Korean, Khmer, Spanish, and English. Just let us know your preferred language when you reach out.
When can I change my Medicare plan?
The Annual Enrollment Period runs October 15 to December 7 each year — the main window to switch. There are also special periods for certain life events. We’ll help you understand which applies to you.
I’m turning 65 soon. When should I start?
About three months before your 65th birthday is the ideal time to begin. Reach out anytime and we’ll map out your timeline so you never miss an important deadline.
