Dr. Rob Ashby, MD, FASAM, DABAM, DABPM – Medical Director

Rob Ashby, MD is certified in Addiction Medicine by the ABPM and a fellow of the American Society of Addiction Medicine. He is certified by the American Board of Pain Management. He has extensive experience in treating addiction including outpatient, residential and detoxification programs and has used buprenorphine (Suboxone®) since it was first available 15 years ago. Only a few treatment centers have medical directors certified in addiction medicine.

Dr. Ashby has been very successful managing people with both pain and addiction disorders. It is impossible to successfully treat this difficult problem without addressing both issues at the same time.

Dr. Ashby believes in the disease model of addiction and that people with addictive disorders deserve to be treated with dignity and respect, but also need to be held accountable for their actions.

Lisa Waknin – CEO

CEO of Silver Sands Recovery, Lisa’s founding principal is to provide a superior foundation for Long Term Sobriety. As the parent of an addict, Lisa knows firsthand the devastation addiction has on all concerned. She works side by side families, helping them bring bottom up to the addict thereby getting them into treatment. Her many years of trying to help her own daughter (sober over two years) has led Lisa to immerse herself in the field of recovery. Teaming up with medical and clinical experts and adding in her own true experiences from running a successful $60M company to being the parent of an addict has given this program a unique perspective. Parents from clients are quoted, “Finally I have someone I can speak with that knows what I went through and knows what these kids need. She’s a voice of reason, has compassion and cares.” Lisa always makes herself available to families in need.

Brian McEnroe aka Bird – VP

If asked how Brian McEnroe got his nickname his answer is quite simply this, “I was as yellow as Big Bird when I got sober eight years ago.” Standing at 6’4″, Bird is the real deal. He knows how to get these kids sober and on a routine to stay that way. Partnering with Lisa, Bird brought his love of sports to Silver Sands Recovery and created a Sports Division that helps our clients just as much as the therapy does. Finding a healthy outlet with team sports such as basketball, baseball, volleyball, brings to the table another dimension in recovery that is needed just as much as any other aspect. Bird knows it takes massive action to get results. Meetings, therapy, clinical care, medical care, sports, work, sober fun, they are all important because when you leave here you need to know to put your sobriety first and to do everything it takes to make you stay that way.

Erik Ish – Program Director

Erik holds a Bachelor of Arts from San Francisco State University and a Masters of Clinical Counseling from Northern Arizona University. He is a Licensed Associate Councilor (LAC) as well as Nationally Certified Counseling (NCC) with nearly 10 years experience working with people in recovery from addiction. Erik sees addiction as the naturally occurring byproduct of life stressors for many.
