About me
I was born and raised right here in Montgomery, Alabama—and, for many years, I have taken great pride in helping families in my hometown navigate the home buying process with confidence and peace of mind.
As a local mortgage lender, I combine the strengths of building trust, networking, and educating. I strive to build deep, meaningful relationships that span past the closing table, and stay visible and engaged to serve as a reliable resource for clients and partners alike.
But at the core, I’m more than a loan officer—I’m your trusted local advisor. I’m here to guide you through the process, break things down clearly, and make sure you feel educated and confident every step of the way. Whether it’s your first home or your fifth, I’ll be in your corner, keeping it simple, steady, and focused on what’s best for you.
I bring that same mindset home with me. As a husband and proud dad to two little girls, I take family seriously—and I promise to take care of yours like I do mine.

Alex is always wonderful to work with every.single.time. I know my clients are in good hands and he looks out for their interest. I always appreciate updates and the communication we have regarding the client and where we are on the file. Secondly, I appreciate him attending the closing. To me it shows our client just how much they are appreciated plus just in case anything needs correcting or if questions arise. I feel it makes us more of a team concept and we always put the client's needs above everything else. Great job Alex! Here's to many more in 2025!

Alex and Kelli were wonderful to work with, they both had such patience with me and all my questions. Extremely professional and knowledgeable in every regard. Both were easily accessible anytime I called with a question. The entire process was one I was a bit leery of , yet they made what I saw as daunting task an easy procedure. Every step of the way they explained the process and what to expect. I was very impressed with the online format as it kept me constantly up to date as to where we were in acquiring my loan- step by step.
