What Our Clients Say About Us
My wife and I have been clients of Mark for over a decade. He truly cares about our finances and is very good at explaining all of our options. We sleep well at night knowing that Mark has planned our retirement with a great amount of expertise, detail and thoughtfulness.
Jesse & Brandi
Working with Mark Hupe has been a wise and beneficial choice as well as a great pleasure and learning experience. I began working with Mark in 2007. I had been managing the finances for my wife and I but decided that professional help was needed to determine the right course to increase and protect our assets as we looked towards retirement. His knowledge, care and concern has guided us to an investment plan that provides protection of assets as well as providing tax-free income in our retirement years. Mark is a man of integrity and trust, and his direction and planning has given us many years of peace from financial worry. We would highly recommend Mark to anyone in search of a financial planner and advisor.
Tommy & Susan
I would recommend to anyone seeking sound retirement financial planning advice to work with Mark Hupe. Mark and I have been working together since I moved to Colorado 26 years ago. I was many years from my planned retirement age at that time, and Mark had the foresight and expertise to set up a plan that has served me well since my retirement over 2 years ago.
Mark has always treated me more as a friend than a client, being both forthcoming when I needed him to be as well as compassionate in time of stress. We have weathered two significant financial crises in our time working together and I have faired better than most during those times.
Mark’s style very much suited my needs. When things were going well, he would reach out occasionally to make sure we were still on the same page. However, when circumstances changed or new opportunities arose, he was quick to reach out and put these situations into perspective and offer me options to best move forward.
I have benefited greatly from Mark’s expertise in navigating the complex nature of retirement finances and the tax burdens therein. I am eternally grateful for the relationship that we have and would recommend anyone with concerns about their retirement income work with Mark.
