    Hear From Our Patients

    I learned many very helpful exercises from the excellent Therapists at Munger. They are a people who care alot about their patients. I highly reccomend Munger for all you aches and pains.
    Munger is the absolute best for hands on care in a private setting. Jim Achatz is the back expert in SE Michigan. He has the experience and know how to get you feeling better and fast.
    Linda is an absolute Angel! She will go way above and beyond to get you feeling better and takes her job to heart. She spends the time with you to make sure you are feeling right and have incredible progress. I’ve tried several others in the area and no one compares to the personalized care you get at Munger! Do yourself a favor and give them a try. You won’t be disappointed!
    After a strenuous year I came back for a “tune-up”! Annie and Jim worked steadily to get me back walking in a much better shape. Thank you for your patience as I recuperated.
    The staff at Munger are friendly, helpful and very professional. I worked mostly with Erica, and she was excellent. I learned so much from her and I am doing much better. I would highly recommend them to anyone in need of PT. They are a wonderful group of people.
    It was a wonderful experience. My knee has improved immensely. Linda and Ann were wonderful. I would highly recommend this therapy practice. Definitely 5 stars. 😊⭐️⭐️⭐️⭐️⭐️
    Wouldn’t trust anyone but Mungers Physical Therapy ! Very knowledgeable , professional, caring staff. Lisa greets you with a smile . Jim treats you as if you’re his only patient. Taking time to really listen to you and implementing a program that is effective. They make you feel like family.
    The whole team at Munger physical Therapy were fantastic! Professional, knowledgeable, kind & caring. Would recommend 💯%
    The staff at Munger Physical Therapy are wonderful! They are experienced, knowledgeable, caring and supportive. They take a valid interest in their patients. And make you feel comfortable during treatment. I've received PT care from Munger for years as well as my family members. I would highly recommend them if you are in need of physical therapy.
    They are all so friendly and are committed to helping you through the pain. I would recommend them to anyone needing PT!
    ⭐️⭐️⭐️⭐️⭐️ Dr. Ashatz is absolutely incredible! He treated my son Ashton’s foot sprain with so much care and expertise. From the moment we walked in, he was warm, personable, and made Ashton feel completely at ease—he even had him laughing through the whole visit! That level of compassion and bedside manner is rare these days. Dr. Munger went above and beyond, and we left feeling grateful and confident Ashton was in the best hands possible. I would recommend him to every single person I know and shout his name from the rooftops—this is the doctor you want caring for your family!
    The staff was very friendly, accommodating, and knowledgeable! They helped improve my pain level and gave me tools to help any future pain with my problems. I’m very grateful and appreciative for the staff and their hard work!
    Physical Therapy with Jim and other therapists at Munger Physical Therapy is the best I’ve ever experienced. I’m 82 and have many sessions of PT through the years I particularly liked their focus on the spine. At each session, they would re- evaluate one’s needs. I also appreciated the hands on therapy at each session. They are fantastic. My needs have been met and I highly recommend this group. You will be happy you choose them.
    This is definitely the place you want to go for physical therapy. Jim Achatz is highly skilled at his craft. While that is always the priority you look for, he also is a great listener, shows empathy for your injury, and also has a great sense of humor. His excellent work ethic and personality flow to the rest of the staff at this facility. If I didn’t have Jim working with me, Anne was there. She also is excellent with her treatment and makes you feel instantly very comfortable with her. She gives the best massage too! There is not anyone at this facility that doesn’t make you feel welcome whether it is Lisa at the reception desk or the interns that work with you on your exercises. I came to this facility 10 weeks ago not knowing if I was going to have full range of motion again with my shoulder. Today I left confident that I can do anything I want to do.
    I was a patient recently at Minger after having a hip replacement. This is the best physical therapy facility I have ever been to. Jim and his staff are very knowledgeable and friendly. I especially want to give a shout out to my favorite therapist, Linda. She was Awesome and really listened to my concerns and helped change my treatment to fit my individual situation so I received the most out of each session. She is a therapist who truly cares for her patients and I was very blessed to have her treating me. Thank you Jim and Linda for your care that has gotten me he where I am today. I can honestly say that without you two I would not have the opportunity to dance at my wedding next month. I will forever be grateful.

    Great place to go for physical therapy. Very professional and caring! So glad I found this place and I highly recommend it!
    Everyone at Munger PT in Clinton Twp is awesome! From ease of making appointments to the professional, thoughtful treatment plans, personable PTs and aides to follow up care , was so appreciated . I had PT on both knees after replacement surgeries. I am super pleased with my recovery results. I cannot recommend them highly enough.
    Jim Achatz is a miracle worker! My 13 year old daughter had a horrible knee injury resulting in months of physical therapy. Jim was the only one that could get through to her. He not only helped her recover but helped her mentally deal with her injury and recovery. She's back to running and high jumping and has an exercise plan to help her.
    What a team!! Let me start with the first person you see, Lisa. She was so welcoming. Her big smile made me feel so comfortable! Even when she was telling me how much I owe I felt like I was having a discussion with a friend. What a wonderful person to have welcoming new and returning clients.
    Next, was Wyatt. What an amazing young man! He always had a smile and great conversation. So much so I didn't realize how hard he was making me work. He is such an asset to this company!
    While i didn’t have Anne as a therapist, she was also very friendly. She always had a “hi Shannon” for me. I would hear her clients talk about how amazing she is.
    Julie!!! She was recommended to me from my homecare PT, and now I know why. I could have gone to a closer location but I am so glad I didn’t. Julie is absolutely amazing! She made me feel special! She worked me so hard, but I always felt it was because she cared. I wanted to do the work and make her proud, she is that good! I had some setbacks and she never stopped encouraging me. She never stopped believing in me. She worked me hard and then she would have a conversation with me about not being so hard on myself. She was my therapist in more ways than one. I feel absolutely blessed that I was able to work with her, and I cannot begin to tell you all how lucky you are to have her!
    This is such an amazing team of individuals! I actually feel sad that I won’t be seeing them every week!
    Sincerely, Shannon Spezia
    I had a complete knee replacement, and did my P.T. there, I would highly recommend them, from Jim, Julie, Anne, Wyatt, and lisa who runs the front .....great group, and a
    very caring and nice atmosphere......
    Munger PT helped me overcome a herniated disc on two separate occasions. Jim is thoughtful in his treatment, listening to his patients and tailoring the treatment plan to align with patient goals. Both times, he has helped me return to an active lifestyle that otherwise I may have lost. Lisa, at the desk, is always a cheerful face and very helpful as well. I’m extremely grateful for their services.
