About Vista Living

Management Team with Unmatched Depth, Breadth and Experience

Vista Living offers a level of leadership and support that is exceptionally rare in residential assisted living. Few, if any, homes can match the depth and breadth of our management team. Our leadership structure includes:

This strong leadership presence translates directly into a higher level of care, responsiveness, and customer service for both residents and their families.

In addition, many members of our leadership team have served in their roles for years. That continuity allows them to develop deep healthcare knowledge, maintain consistent leadership practices, and build meaningful long-term relationships with residents, families, and staff. The result is a well-established operational structure, smoother day-to-day management, and a culture grounded in trust, accountability, and compassion.

Our leadership team also helps foster a positive, mission-driven environment where professionalism and resident-centered care are the standard. This stability at the top contributes to stability throughout the organization, including a dependable and committed caregiver team.

We are proud to offer caregivers not only competitive pay, but in many cases room and board as well, with private bedrooms and bathrooms in our homes. This creates a uniquely attractive work environment and helps us retain quality caregivers who are deeply invested in the residents they serve.

That combination of leadership strength, staff stability, and personal commitment is one of the many reasons families choose Vista Living.

“At Vista Living, we’ve built a leadership team unlike any other in residential assisted living, a team with extraordinary depth, experience, commitment, and heart. With full-time professionals leading every key area of our operations, we deliver an exceptional level of care, responsiveness, compassion, and service that families can truly feel. Our unwavering commitment and strong, stable leadership, together with our dedicated caregivers, create a foundation of trust and genuine compassion that defines the Vista Living experience.”

Brett’s Story

2010: Grammy and Brett’s kids at her 100th Birthday!!

“My introduction to senior living came when my 96 year old Grandmother “Grammy” (hope I get her genes) moved into a large senior living community across the country from her many family members and friends. The move ended up being a poor decision and experience for her. The community advertised a Four Seasons experience and did not deliver anything even close to this promise. The senior living community ended up being too sterile and impersonal. The culture was bureaucratic and authoritative. The staff had little or no time for individual needs and took away what she enjoyed without any explanation. We felt like our concerns for her were being ignored. Our Grammy would have had a much better experience in a more personalized and friendly environment that would have given her much more peace, joy and love through her last days. This experience really stuck with me.

After Grammy passed (at the incredible age of 103!), I began learning more and more about assisted living until deciding to pivot my career towards creating better living environments for seniors. I used my background investing in housing and creating teams to help launch Vista Living with some of the very best professionals in senior living. Fortunately, I found that in Kyle and Vista Living was born. The sense of truly discovering and nurturing the needs and lifestyle desires of our residents is at the core of all we do at Vista Living.

I feel very fortunate to have joined forces with our entire Vista Living team. They all have such big hearts, engaging personalities, decades of experience, knowledge, motivation and passion for providing great care.

Before we opened Vista Living in Phoenix, Kyle and I spent two years researching the best partners, services, locations and assisted living design. The research included visiting over 50 assisted living communities in three different states. We took notes on what worked and what did not in each place, and most importantly what the manager and caregivers do to create the right care environment. We also built relationships with dozens of leading senior living experts for every aspect – care, services, architecture/design, etc. Every single detail of the community and the business were carefully planned, designed and implemented with compassion. I feel privileged to offer a better model for senior living.”

Kyle’s Story

Kyle and his dad

“I used to get this ‘old man’ feeling knowing that things will never stay the same. That one day, I would miss very much what I have today. I reminded myself of that when my dad went deeper into dementia. I had this fleeting opportunity to show him my gratitude and fulfill part of my life’s obligation to make sure he is comfortable and around people who like him. As I continued to work in the senior living industry, people would still remind me about his smile. When I see pictures of my dad I am reminded of his friends in the senior home and the workers with big hearts who looked after them. I hope we can continue this magic with Vista Living and make every moment count.”

Brett Weisel

CEO, Co-Founder

Brett Weisel co-founded Vista Living in 2015 and provides leadership, strategic direction and management to the Vista Living team. He brings over 30 years of experience to a business with tremendous social impact. Brett takes pride in his dedication, work ethic, knowledge, vision, expertise and attention to detail. He believes the most influential businesses are built on excellence and Vista Living is committed to this mission. Brett is driven by integrity, quality of service and focus on creating the best residential assisted living model.

Previously, Brett was a partner at two investment banking firms for 17 years and was the founder and general partner of a single-family home focused fund for eight years.  Brett learned how to build great teams from these careers and the details essential for creating well-run companies.

Brett started Vista Living because it was clear that boutique residential assisted living was a great opportunity to provide a better end-of-life experience for our seniors when done well. Having witnessed a less than perfect end-of-life experience for his grandmother, Brett envisioned a better model.

Founding Vista Living has allowed him to follow his entrepreneurial spirit and pursue a passion for creating exceptional homes with open floor plans that bring great people together in a joyful, social and connected community.

Brett enjoys skiing, tennis, reading, hiking and bringing friends together. He is a graduate of the University of California, Berkeley, and he and his wife, are proud parents of three young adults.

Working full-time with seniors is Dean’s passion, as it genuinely brings him a sense of true fulfillment. Since he was raised by his grandmother, great-aunt, and great-uncle, he naturally learned ingrained love, respect, and appreciation for seniors. As Dean says, “Providing unparalleled services in exceptional home environments is a professional dream come true.” Also, “there is no greater honor than to care for those who once cared for us!”

Kyle Oura

Co-Founder

Kyle co-leads quality control for Vista Living.  He brings nearly 10 years of senior care experience to the helm. Kyle is a CPA and self-proclaimed “numbers guy” who realized in his early 20’s that he loved working with seniors after his dad suffered a stroke and developed dementia. Kyle was the primary caregiver for his father and his experience caused him to change directions and seek out opportunities in senior living.  Soon, he landed at AgeSong, a leading edge assisted living company where Kyle worked in both finance and operations. He even moved his dad into the community – a full-circle life experience for him.

Kyle dreamed of starting a senior care company based on his personal and professional experiences. He wanted to offer happiness as a standard to seniors in need of care and his dream came true when Vista Living opened its doors.  

Kyle has endless energy. He has worked at leading companies such as Deloitte, Prudential, and Greystar investing in $10 billion projects and served as a Board Member of Kimochi, a not-for-profit senior center in Hawaii.

We love his story and his experience, attention to detail, and passion for creating fun environments for seniors. Kyle spends most of his free time adventuring with his young children and incorporating a love for elders in their hearts.
