About Me

Let's Make Your Dream Come True

Being in the mortgage industry had never crossed my mind when picking a career.  Real Estate – yes, mortgage, not so much but only because I knew nothing about it.  Like most people, when thinking about getting a loan for a house, I thought, “I’ll just go to the bank or jump online for a loan.”  Now that I am a Mortgage Loan Officer, advising first time home buyers and veteran homeowners, all I can say is I was wrong about my previous statement.  I am proud to be an advocate in this industry and to educate all of my clients about the ins and outs of home loans and mortgage.


The passion I have for assisting those seeking a mortgage for their first home or their fourth home is undeniably honest.  There is an abundance of information and resources out there for those looking to purchase or refinance their home but the real question is, can you trust that information?  Do you know the person on the other side of the screen looking at all your private data – finances, social security, previous address, and work history?  As an independent mortgage broker, being able to talk to my clients and understanding who they are and their goals is the biggest difference.  You are not just an application or a figure when it comes to working with me.


When not walking through the home loan process with my clients, I am a mother of two adventurous little ladies, a wife, and an avid crocheter – my home is never without a new a decorative throw, my kids never without a new hat or scarf!  The community in San Ramon is a big part of who I am as well.  Being part of the PTA and volunteering at the schools is important to me as a community member and a mother.  My family and I also love going to the Farmers Market at City Center to support local small businesses and enjoy all the festivities San Ramon has to offer.


We are a local family-owned business that works with everyday people to get home loans. We advocate for our clients to help them succeed and grow. We value being a trusted source of advice and knowledge. We believe homeownership can dramatically change one’s financial life for the better- so our clients can focus on things that matter. 

We offer one-to-one counseling, support, and top-notch customer service. If you are calling or emailing us, you’ll be talking directly to an experienced loan officer. No automated operators or customer service representatives giving you the run around here. And if we are meeting you in person, we’d love to meet you in a local coffee shop or a local brewery (after all, the West Coast does these two things best!)

As Mortgage Brokers, we are able to shop many different lenders on the market (rather than being tied to one bank) ensuring our customers have the most choices and best options. Our favorite part about about what we do is often surprising our customers with options regarding their financing that they didn’t even know they had. 

Here is a sample of the type of loan programs we offer: 30yr mortgage, 20yr mortgage, 15yr mortgage, 10yr mortgage, 1yr ARMS, 3yr ARMS, 5yr ARMS, 10yr ARMS, Conventional, Jumbo, Piggyback, FHA, VA, USDA, Reverse, Cash-Out Refinances, Renovation and Construction loans. Whether your situation calls for Full Documents, limited Documents, Non-Owner Occupied (Investor), or Multi-Family, we’ve got you covered!
