Administrative Team

Solid Landings seeks to employ the brightest in the industry. Our Executive team members possess the experience and innovative knowledge necessary to provide their teams with the guidance, skills, and training tools they need to successfully communicate and treat clients. They are well versed in some of the most effective, innovative, and promising treatments and therapies. Many of our staff members have also personally dealt with addictions, and understand the importance of respect, empathy, understanding, and compassion for anyone trying to get on the path to recovery.

Steve Fennelly, Co–Founder, CEO

Steve co-founded Solid Landings Behavioral Health following his own recovery from drug addiction. He credits his personal insights and understanding of the life of an addict for his passion and goal for Solid Landings, which is to provide all its clients with a calm, supportive, family environment to allow them to focus on their recovery.
Steve holds a B.S. in Accounting and Finance from Albertus Magnus College in New Haven, Conn., and has extensive business experience. Steve managed his first successful construction company, Fennelly Construction, while finishing his degree in 2000. In 2004, he started A Plus C Quality Construction, at a time when addiction was taking ahold of his life. He moved to Southern California to try to turn his life around, leading to his founding of Solid Landings with partners, Mark Shandrow and Elizabeth Perry.
From a small sober living home, Solid Landings has become a nationally recognized facility known for its outstanding care, excellent services, and exceptional support for its clients.
Steve’s philosophy is to offer personalized care and concern for his clients. He believes that families are part of the healing process, and seeks to involve family members in the treatment of their loved ones. He insists on creating peaceful, family-like living arrangements where clients can focus on themselves and their recovery. Although there have been plenty of opportunities to grow Solid Landings in size, Steve has made a conscious decision to grow smartly, in order to provide personal support for clients.
He remains an active sponsor for people attending Alcoholics Anonymous meetings. He has also mentored a number of business owners to build businesses that promote a personal connection with their clients.

Gerik Degner, CFA, President

Gerik joined Solid Landings in early 2016 and brings with him nearly 20 years of refined experience in corporate finance. Most notable is Gerik’s recent work as co-founder and partner of Alpine Pacific Capital – a middle-market private equity investment firm that focuses on a wide variety of industry verticals including healthcare.
“I am eager to work with a company that is so deeply committed to helping those men and women who struggle with addiction,” Gerik says. “This company has established itself as one of the best in the industry, and I am excited to make it even better in the days, months and years to come.” Gerik was raised in Colorado and graduated with a B.A. in psychology from the University of Colorado. He is a Chartered Financial Analyst (CFA) charter holder, a member of the CFA Institute and is chairman of the Orange County chapter of Gen Next, an exclusive organization of executives dedicated to learning about and becoming engaged with the most pressing challenges facing future generations. In addition to portfolio company boards, he also serves on the board of directors for the Orange County chapter of the Association for Corporate Growth.

Elizabeth Perry, Co–Founder and Chief Cultural Officer

Elizabeth has an extensive background in the marketing industry and her experience and skills in the areas of sales and advertising have been key in undoing fears and misconceptions about drug and alcohol treatment and getting more people to learn more about Solid Landings. A stint as a bartender, which ironically exacerbated a developing alcohol problem, gave Elizabeth a unique insight into the mind of a person who is addicted to substance use, and which led her to work with partners to form Solid Landings.

Mark Shandrow, Co-Founder and Chief Revenue Officer

Mark’s enthusiasm and dedication to reaching positive outcomes for our clients has helped build Solid Landings as a center of excellence for the treatment of substance abuse. Mark’s background in both the private and non-profit sectors informs his initiatives to build business relationships and allow Solid Landings to grow and reach out to more people.
Mark holds a B.A. in Economics from the University of New Hampshire, and has wide experience leading several non-profit organizations and businesses. He was actively involved in Bikestation, an alternative transportation consulting service that oversaw millions of dollars from local, state, and federal agencies for bicycle and pedestrian transportation. In 2005, he received his California real estate license, and soon opened Shandrow Group, a boutique real estate brokerage whose business includes managing and selling assets for large financial institutions such as Bank of America, JP Morgan Chase, HUD, and Fannie Mae.

Tanisha Porreca, Chief Operating Officer - COO

Tanisha’s role is making sure that operations at Solid Landings are smooth and efficient and that all the clients’ needs are addressed and met. Tanisha’s background and passion is in helping those who are in need. She previously worked in the criminal justice system in the pretrial release department. She also worked in the non-profit sector, helping the hungry and poor.
