Marvel Coleman

Owner & Crisis Stabilizer

As a life-long resident of Milwaukee I have made a commitment to improve the lives of those in my community. Quality of care is very important when providing services for children and young adults. The future lies with them so having a solid team of professionals to help as they plan their future is essential. I divide my time between working with the kids and working with our team to ensure they are the best they can be.

Michael Beal

Crisis Stabilizer

I’ve been working with kids for a few years by teaching karate. Through my own training I’ve had to work a lot on patience and discipline, and I’m able to demonstrate these skills when helping with others. My main approach to working with youth is to not only just help them with whatever they’re going through, but to really work with them on being able to think about what they want for the future, and realizing the steps towards that goal.

Yusef Gray

Lead Crisis Stabilizer

I am a person who believes that our youth of today are also our future doctors, teachers, sports coaches, and entrepreneurs. I enjoy listening to youth as they talk about their dreams as it also gives me the opportunity speak and give them the instructions and tools needed to build their dream into a reality. We as individuals, regardless of age, all have days of dealing with frustration, stress, and even depression. However, how we deal with it is important. As a crisis stabilizer I provide to our youth and families ways to deal with these situations as they may arise, to avoid, decrease, or eliminate crisis reactions.

David Guetzkow


I enjoy working with youth. I encourage families to expand their comfort zones by trying new things and testing new ways of doing things in a controlled and safe setting. I am always open to advice and trying things the way families want it done.

Keisha Harris

Crisis Stabilizer

I’m a believer of positive change, and my beliefs are the reason why I advocate and provide positive role modeling skills, build support and gain the trust of the youth that I come in contact with. As a crisis stabilizer I provide and share ideas on ways to better deal with crisis situations without added frustration.

Veronica Smith

Crisis Stabilizer

I am a vibrant person who is fairly new to this career, however, I’m very experienced in making a difference in others’ lives. Interacting with youth has always been a passion for me. It pleases me to make a difference in one’s life by communicating (words of encouragement), listening (to hear what makes another feel the way he/she does), and just spending time with one (everyone wants to feel special and one-on-one attention gives that). My goal as a crisis stabilizer/ mentor is to give my client(s) the keys to unlock a future of success.

John Sumlin

Crisis Stabilizer

My name is John Sumlin, as a youth growing up in the City of Milwaukee and as the oldest of five children, I looked outside of my family for a “mentor” figure. I recognized the value in that type of a relationship and therefore, sought out a career where I could provide that type of support to our youth.
