“I shopped around a bit for a broker, and was referred to John by a coworker. He was by far the most personable, professional, and proactive broker that I interacted with. He promised me that he was doing everything he could to protect my family’s money and get us into a house that we love, and he did. The bottom line is he got us our desired results, he offered great advice, and he earned my trust and confidence. I would recommend his services to anyone looking for a knowledgeable and passionate mortgage broker.”

“John went above and beyond for us…we were trying to figure out if we wanted to refinance and do some work to our house or move into something else. He put together a great refinance package with our strict requirements, while knowing we could ultimately go a completely different direction without applying any pressure. Would totally recommend John and his team to any of my friends. Thanks John!”

“Have been working with John (Capitis Financial) for a couple months now; he is very patient and understands our needs as first time home buyers. John has been amazing and answers all our questions, I think we have found our long time broker. He has the clients best interest in mind which is very refreshing. A++”

“John is an extremely talented and hard-working individual. He works tirelessly for his clients, to not only make sure they find the right financial solution, but to help them understand the financing process along the way. His personable and relatable demeanor, as well as his work ethic, put John well above the average mortgage broker. If you are looking for financing, I definitely recommend John at Capitis Financial.”

“Working with John is always great and this time was no exception. When my clients relocated from Orange County, they were referred to John for their loan. John did not disappoint. In a fast paced market, John got the clients pre-approved quickly and was always available via telephone or email whenever I needed something from him pertaining to their loan. John is not only great to work with professionally, but he is also one of the nicest and most genuine people you will meet. I look forward to many more transactions with John in the future.”
