I came of age during the AIDS crisis and everyone I knew was a caregiver, even if they needed help themselves. The difficulty of the caregiving role, and the emotional turmoil, anxiety and fear that came with it, changed my life and the way I looked at the toll that caregiving can bring. Helping someone actually grow from these experiences rather than get ‘traumatized’ has been a focus of my work ever since.

Paul StraussChief Information Officer

Paul serves as the chief technology officer of Carallel, where he oversees all technical aspects of Carallel’s digital products and services as well as day-to-day operations and maintenance.

Paul has decades of experience leading application development and design projects for high-profile enterprises, with particular interest in content management, digital asset management, application integration and subscription billing systems. He has held leadership roles with Playboy Enterprises, Digital Work and Platinum Technologies.

Paul earned a Bachelor of Fine Arts degree from Tulane University in New Orleans.

Caregiving is one of the most challenging aspects of life. If there’s even a small way that my experience can improve the quality of life for caregivers and their loved ones, that can be very rewarding.

Ankur JainChief Technology Officer

Jena MoschellaDirector, Product and Service Delivery

Matt earned his BA in Psychology from Denison University. Ever a fan of skiing, he lives in New Hampshire with his wife and three daughters. 

Caregiving has been such an isolating experience. I wish I’d had more resources and help early on. So I've made it my life's work to help as many fellow caregivers as I can.

Perry MimmsProgram Manager and Care Advocate

I know as a family caregiver how hard it can be bearing witness to those you love and value declining over time. I like being there for people when they need it.

Every person is likely to experience being a family caregiver, needing a family caregiver, or both at some point in their lives. No matter what the situation, it’s an isolating and overwhelming experience. That is why I am dedicated to doing my part in improving the experience and making it a tiny bit easier for those involved.

I am a caregiver for my mom and have experienced up close the extreme difficulty of trying to fill a role that I have no training to do and no one to turn to for help.  It is at times an unsettling and frightening position to be in.  Carallel's mission and impact immediately resonated with me because I am living the challenge of being a caregiver myself.

I know firsthand how difficult and stressful caregiving can be, particularly if you live far away. You have to make decisions that you are ill-equipped to make and the internet is full of conflicting information. I want to ensure caregivers are confident in their decisions and the care they provide.

With almost 20 years of industry experience and an approach centered around person-empowerment, she works closely with individuals, health systems, Accountable Care Organizations (ACOs), payers, manufacturers, technology and community partners to promote equitable high-quality care.

Created to Thrive allows her true mission, coaching, and transformation experience to shine through her advisory, products, and services.

As a caregiver of my two Latino, Spanish-speaking only parents, I've struggled to understand our collective needs, and even more challenged identifying and navigating available resources that really connects with their culture and lifestyle. Caregiver support is critical to any patient engagement strategy. We are the conduit to organizing and coordinating healthcare services for our loved ones. Equally important is recognizing the costs, burnout and stress caregivers carry each day as we try to maintain a normal lives. This is especially the case with underserved communities, where way too often, individuals are supporting their own young families while engaged in the health of older parents, often without the same access to health services and growth opportunities as other groups.

Roy advises Carallel on commercialization strategy and our quality-focused programs.

He is part of Avalere’s Commercialization and Regulatory Strategies team as a senior advisor. He is a medical oncologist who has been in practice for more than 20 years.

Caregiving for my mother, who has dementia, has been a bewildering experience. At Carallel, we are building a modern, nationwide, real- time coaching service to help caregivers like me manage the hard work of stabilizing their loved ones. Without support, these experiences can become the tipping points for medical, employment, financial, and social downward spirals for patients and their families.

Leigh Ann RugglesGrowth Advisor

Leigh Ann Ruggles is an executive healthcare leader with expertise driving business growth and market share for digital health companies to increase company value. She has a strong background across the entire client lifecycle, from revenue acquisition to retaining and growing market share, with deep expertise in all facets of Go to Market functions. Leigh Ann is known for her ability to build high performing teams as well as her strong relationships within the healthcare market, with the ability to partner with prospects and clients to understand market needs, build and shape solutions, and create new revenue streams.

Most recently, Leigh Ann served as Chief Commercial Officer for GuideWell Venture Group, the diversified business arm of GuideWell / Florida Blue, where she was hired to oversee growth and clients across a portfolio of companies. In this role, she founded and built high performing sales, marketing and client success teams and created a strategy to maximize the Venture Group portfolio by replacing unprofitable business with business in more attractive high margin company products.  During her time there, she doubled the valuation of one company, leading to a successful exit, while pivoting the product and market approach of a second company to address the fast-growing market for value-based care.

Prior to GuideWell, Leigh Ann served as Chief Commercial Officer for Onlife Health where she was responsible for the entire client lifecycle, holding P&L responsibility for acquiring, implementing, retaining and growing clients and market share.  During her tenure, she pivoted the product strategy from a commoditized offering to higher value products to drive company growth and value.  Under her leadership, the company doubled the number of clients and increased annual revenue by 60%, ultimately selling the company for more than double its original valuation, without taking on external capital.
